WheelchairDriver

hello everyone. On Monday, I am purchasing my 5 year anniversary wheelchair. The quantum rival rearwheel power wheelchair. I want to add different color/tread tires than what comes with it. I cannot find anywhere the tire sizes, only the rims; 14" x 3" rearwheel and Castor is 6 inches. I've never bought tires for a wheelchair before I always Kept the ones that came on it for the last 6 years. I don't want to change anything on the wheelchair just want tires that will fit on the rims, hoping I can find different rims that are the same size, and slide right on like the stock wheelchair would have. Can anyone help me with this? Thank you, I really appreciate it!

I've never bought tires for a wheelchair before I always Kept the ones that came on it for the last 6 years

Rear tyres for a powerchair are almost universally 14 inch. And the correct terminology varies. But 300 x 8, 3.00 x 8, 14 - 300 - 8, and all sorts of variations are used. Same with casters.

The important info is this for drive wheels:

Rim = 8 inches diameter.
Tyre is 300 or 3.00 (THREE INCHES) wide, and fits an 8 inch rim.

As for wheels, people normally change these for reasons of fitting either wider, tubeless, different profile, etc. Why are you wanting to change them? There's no point if you are fitting NON tubeless, stock sized foam, air filled, tyres? You will find it hard to find plug and play "alternative" wheel rims in any case.

Munky,
You have not filled in your signature or location so we have no idea sources to suggest. In the USA, I'd look at MonsterScooterParts.com I got good service from MSP on a pair of SLA batteries for my Pride Wrangler. If you or your caregivers are handy, I'd suggest Ebay. The key is in knowing what you are looking for as it's far cheaper if you can source from a non-medical outlet.

I've never bought tires for a wheelchair before I always Kept the ones that came on it for the last 6 years.

This is amazing to me.
I get through at LEAST four and usually 5 sets of bigger 10 inch caster tyres a year, totally worn away to the canvas and in danger of failing.
And stock grey 14 inch powerchair tyres were worn to the same level after about 5 to 8 months depending on type.

How on earth do you get 6 years? Are you a full time user (all day)? Do you just stay at home all day?

Same with batteries. I used to throw away a set of 70Ah batteries every 8 to 10 months. Because range, and or Torque (power), just fell away to the point where it stopped me doing what I do...
Recent fast charging, better chargers, multiple daily top ups, has extended this to around 3 years though now. The only way batteries can last longer is if you barely discharge them.

And motors. Swapped around every 18 months to 2 years (4 pole) and the original (early) 2 pole ones were replaced about every 9 months when they were completely worn out.

I had problems last year in the summer when I was outside. There was no tread on those stock tires so they cannot grab to the grass or whatever and I spend a lot of time in the summer in my yard because it is a fairly large yard. I used a center Drive last time and now switching to rearwheel because I tried it and that helps me a lot to get through things. I was going to do air filled, but I was told about how fast they go flat. So I am going with pneumatic tires. I want it to look just like stock size, just more grip and tread on the tires, so I don't get stuck again

I live in Duluth, Minnesota. So 8 of the months are way too cold for me to go outside so I am usually hibernating in my bed. During those months. But in the summer. I am out as much as I can. C4, C5 spinal cord injury paralyzed from shoulders down. And I've gone through a few batteries, that's about it. I don't go in my chair all day long in the summer, just a couple hours until my neck is killing me.

I know the rims are 14" x 3" and the caster wheels are 6". I just really want to know what size tires go on them. Not too small where it's mostly rim and not too large where there is no room between the tire and the fender or whatever. I'm hoping to find the color black with some good tread instead of the flat wheels looking like they have tread when they really don't. Kind of knobby tires, oil like all season you get for your cars. LOL.

is that better, signature and whatnot?

Yes always nice to know peoples location.

very true!

14" is NOT the rim diameter. That is the outside diameter of the tire. The rim is 8" diameter with a 3" tire, so 8" + (2 X 3") = 14". As John already said, the tires are listed in various ways: 300 x 8, 3.00 x 8 or 14 - 300 - 8 and probably some others. One dealer's web site shows an example as: 14"x3" (3.00-8) Foam-Filled Mobility Tire.
Ciao,
Lenny

No. The rims on the drive wheels are anything between 1.75 and 2.25 wide, and 8 inches in diameter depending on chair. And the CORRECT sized tyre is a 14 inch (incorrect description used by powerchair manufacturers) x 3. The actual size you look for or 300 x 8 or 3.00 x 8.

That said you will be hard pushed to find off road style tyres in that size. As you have found out.
But... A 350 (3.50) x 8 tyre WILL fit, and these are available in off road style. But:

a) they are oversized for the rim. So will be pulled in at the bead slightly, but still work OK. And:
b) they are 1/4 inch taller (no prob) and go inboard and outboard by 1/4 too. See if you have enough clearance. If not remove wheel and add spacers (washers) and replace. For these search for 350 x 8 or 3.50 x 8 like here: http://www.shirebikes.co.uk/collections/tyres-tubes

Specifically here: http://www.shirebikes.co.uk/collections ... obbly-tyre
And if you want wheels (will not fit straight on but can easily be made to fit) http://www.shirebikes.co.uk/collections/wheels

And this allows greater tyre options too.

As for casters you do NOT want off road style casters. A caster is not meant to grip. It goes wherever its pushed. An off road style tread pattern hinders this and messes up the steering...

And I have to add, if width isn't an issue, pride offer some wider (very slightly) tyres and smaller diameter rims, 400 (or 4 inches) wide as a stock stupidly expensive part. But in grey.

Or you could fit some of these tyres http://www.wheelchairdriver.com/images- ... hair-7.jpg
On these rims: http://www.wheelchairdriver.com/images- ... /hegar.jpg

And get a better ride, with bigger sidewalls and lower pressures, true off road ability and grip on sand etc and high floatation so they don't sink or get stuck. And tubeless at the same time so punctures become extremely rare, and at the same time look cool!

This is actually very easy to do. Negatives are that on THAT chair it will add 6 inches to the width. Width is no problem on my own chairs, because I build them very narrow to allow for the fatter tyres. But if a 6 inch gain is acceptable then fit these you will not look back. Better in every way. These are 14 in diameter. But on a wide rim, which is only 6 inches diameter.

I absolutely love those!! Both tires and rims! The initial problems I see is that it's in the UK, I don't know about shipping if you can even do that and how many pounds? For money equals a US dollar?? And how do you get it to fit your lug style? Sorry, I am very new to the wheelchair accessory things and have just settled for what they gave me. But I don't want that anymore

wow, I've got so much to learn! I want to buy these right away, but it looks like I won't be able to because of my knowledge, or lack thereof. I thought it was going to be similar to cars, which would have been easy but I guess not

I would love that, but I don't want to sacrifice any measurements to how wide the chair is. My current chair cannot get through a lot of doors, but this new one should have no problems, which will help out a lot.

The problem then is that you are limited in tyres as there are very few made in 300 x 8 that are the same width as yours. The 350 by 8 will fit, on your wheels, and are available with an off road style. http://www.shirebikes.co.uk/collections ... obbly-tyre But its all style because they are still skinny, so sink in mud, sand etc.

And these will add 1 inch to your chairs width.

I would not mind getting a little bit of a larger rim. As long as it doesn't change any of the measurements of the chair; height, width, length, etc. also, I don't want to rims to take all focus for many other part from the chair, to a point, of course. Like the monkey rims or whatever they are would be on some, but the solid steel huge rims where that is mostly what you see/focus on the chair, I don't really care for. I plan on putting other things; colored lighting, decals, painting rims, etc. you know what I mean with all of that?

I would not mind getting a little bit of a larger rim. As long as it doesn't change any of the measurements of the chair;

But that's the point. A chairs width is determined by the width of its batteries, plus width of motors plus width of wheels/tyre combination. Its just maths. Its the thing that determines minimum width.

To keep the width down to 25.x inches on THIS chair http://www.wheelchairdriver.com/images- ... r-1200.jpg required a radical redesign, with the whole centre section narrowed, motors moved inboard by 3 inches each side, and the batteries turned around 90 degrees so they are longways.

So since pride (or anyone else) have not figured this out yet, you cant fit wider rims, or wider rubber without making your chair too wide. The only way they managed this was to fit small batteries in the "EDGE" chair, and managed to lose just 1.4 inches... The smaller batteries are only possible with both loss of range and/or slower chair (lower gearing.)

So...

If you want to fit the 350 off road style tyres to new or your existing rims you will make the chair 1 inch wider. If you want to fit the 145/70 or 6.00 sized all terrain tyres that I use, your chair will end up some 6 inches too wide.

THESE rims are not steel. But aluminium, I simply polished it, are very lightweight, take tubeless tyres, and are cheap and available in many sizes and widths!

And they look way better than a bunch of paint or fancy trim... If you saw these in real life you would want a set! In fact the whole chair is a chunk of super neat way cooler than stock engineering!

The wheels are actually aircraft nose wheels, or race kart wheels see here http://www.hegar4.com/zc150/index.php?m ... x&cPath=98

I would like the chair to not get any more wider. If it does, it will only fit in handicapped doors in my area. And it will definitely not fit in the tattoo shop, which I have been waiting to be able to get in there. I don't really want to have to do a lot of cosmetic changes. If I don't have to. See, my caregiver who would be helping with this.... Well, with the parts he can.... Is your stereotypical huge nerd that always plays games. He knows nothing about all this and there is no way I can direct him and help out since I do not have any usage of my arms. This is why would prefer them to slide right on. Of course I know I have to have a shop mount the tires on the rims, but that's not a problem whatsoever. What size are those rims in that picture? The tires look great and would help me but might be too large, especially when I go places such as Dr. offices, since for some odd reason those offices are small. I like the knobby tires previously posted on this thread topic. But you are right, they do look pretty skinny. I would just love to have a chart or something like that. That would tell me exactly what they would look like on my chair or something like that. I don't mind adding an inch or 2 to go width, but I don't really want to go any much more than that. Also, I could handle an inch or 2 for height, but no more than that, or I will be hitting my head on a lot of things.

I hope I am not sounding like a broken record and becoming annoying. This is all new to me on finding the perfect tire and rim to purchase. And due to being on disability, if I purchase something, it better work out great, you know what I mean? I do appreciate everyone's help. I am learning some and finding sites I never found. I still have a lot to learn. Which sucks since I get my chair in 2 weeks and it's almost summer, when I am in my chair the most.

also, I would prefer different rims than what it comes with. Not so much like what you have chosen here, but something cool and interesting. Kind of like the "tuner cars" LOL. But I cannot sacrifice 6 inches on how wide it will be. One or 2 absolutely tops!

in the picture you gave of the chair on the wheelchair Van ramp..... I like that to a point. A little too big and wide but not by much.and I would love better tread to go through gravel and dirt like I always do and just around the yard or the beach, which is nothing but little rocks and other things. Lots of other places with different type of land.

If you are a car nut as I was, wheel size, weight, and width is what looks cool. Fat tyres look cool. Not the style, that's secondary. Hairdresserish in fact! But you will not find a selection of different wheels to choose from anyway other than used on other powerchairs as very little uses these sizes. And they all look crappy because they are too skinny...

So you will not find anything. If you do it will not bolt straight on. Some engineering or adaptation will be required.

The reason people change wheels is because they want a lower profile, larger diameter, wider rubber, bigger sidewall, runflat tyres, more offset, less weight, bigger brakes, etc. Many reasons. But seldom just to have the same size with a different style - unless maybe boy racers - and they don't know why they are doing it....

EG I wanted Runflat tyres, less body roll, less sidewall flex and a more planted feel on my van. Vans are not renowned for sharp handling and lots of "feel". So I lost the skinny 16 inch rims, with 225/65 tyres and fitted some 18s. These were better but not enough, so swapped them for some 8.5 wide rims, 19 in diameter, with Runflat tyres and that were 245 wide and much lower 50 percent profile. Why did I choose this wheel? Because it was the right size, correct offset, correct PCD, correct width, correct diameter, and very very cheap!

I didn't choose a wheel, then find a tyre. I choose a tyre of the largest width that didn't quite hit anything, that was the profile and diameter I wanted, and then found a wheel that allowed me to use it.

A little too big and wide but not by much

Its much shorter than your rival. By some TEN inches!
Its 25.3 inches wide. So the same width as the Rival to the mm...
It seat can be much lower too.

It works with full sized batteries, and more power than yours, on beaches, snow, sand, and it wheelies like mad. Also greater ground clearance. And much better build quality. And instead of a 75Amp controller it has either a 100Amp one (more torque)

The NEW one is exactly the same, but even shorter! And has 3x the speed, 3x the range, and can be charged much faster, and its 45v lithium battery is half the weight and holds 3x the energy! And a 45 volt system and a 150Amp one. The big manufacturers are not trying.

Getting back on track, if I were you I would take a look at the wheels pride offer. They do some 1 inch wider, off road (ish) style tyres that are 1 inch wider each side. They wont help a lot off road or on sand etc but they are better than stock 3 inch tyres. That will add 2 inches to your chairs width.

So making it 25.25 + 2 = 27.26 wide.

This is amazing to me.
I get through at LEAST four and usually 5 sets of bigger 10 inch caster tyres a year, totally worn away to the canvas and in danger of failing.
And stock grey 14 inch powerchair tyres were worn to the same level after about 5 to 8 months depending on type.

How on earth do you get 6 years? Are you a full time user (all day)? Do you just stay at home all day?

Same with batteries. I used to throw away a set of 70Ah batteries every 8 to 10 months. Because range, and or Torque (power), just fell away to the point where it stopped me doing what I do...
Recent fast charging, better chargers, multiple daily top ups, has extended this to around 3 years though now. The only way batteries can last longer is if you barely discharge them.

And motors. Swapped around every 18 months to 2 years (4 pole) and the original (early) 2 pole ones were replaced about every 9 months when they were completely worn out.

I am still running the same solid rehab tires that came on my Jazzy when I got it around 2.5 years ago - Far as I know they were what came on the chair many years back - though I was told it had very little use before I got it. The center tread is getting thin, but still quite passible. I spend a lot of time in the chair and do a lot of miles in the Asylum which has a fairly rough concrete floor, and which I try to spin a bit on turns... I also have gotten stuck many times and done a lot of spinning as a result... I haven't noticed the tires turning a serious yellow or crumbling the way you say grey tires do... (I'd consider swapping the tires but I'm hoping to get the Redman finished soon and am trying not to put any money into this chair that I can avoid...

Current batteries are about a year and a half old, and still sort of work, but they are getting tired...

I've swapped out the motors and controller / pod, but that was because of my "swimming adventure" not because of any normal wear failure...

There was no tread on those stock tires so they cannot grab to the grass or whatever and I spend a lot of time in the summer in my yard because it is a fairly large yard. I used a center Drive last time and now switching to rearwheel because I tried it and that helps me a lot to get through things. I was going to do air filled, but I was told about how fast they go flat. So I am going with pneumatic tires. I want it to look just like stock size, just more grip and tread on the tires, so I don't get stuck again

I should point out that pneumatic tires ARE the same as air-filled ones... The WC industry uses split rims and tubed tires, which DO go flat quickly in the case of a puncture. However if you can find TUBELESS tires and compatible rims that you can make fit on your chair, there is much less of a problem with flats...

Barring a gross puncture of the sort that totally cuts the tire open, a typical small object will only give a slow leak - this is part of the nature of a tubless tire. If you use puncture sealing goo inside the tires the way that BM does, you are even less likely to have a problem.

The air filled tires will give you a much softer ride than the solids that the WC industry tries to stick people with.

A little too big and wide but not by much

Its much shorter than your rival. By some TEN inches!
Its 25.3 inches wide. So the same width as the Rival to the mm...
It seat can be much lower too.

It works with full sized batteries, and more power than yours, on beaches, snow, sand, and it wheelies like mad. Also greater ground clearance. And much better build quality. And instead of a 75Amp controller it has either a 100Amp one (more torque)

The NEW one is exactly the same, but even shorter! And has 3x the speed, 3x the range, and can be charged much faster, and its 45v lithium battery is half the weight and holds 3x the energy! And a 45 volt system and a 150Amp one. The big manufacturers are not trying.

I do not really have a choice in the wheelchair I get. Unless I pay for it myself. The physical therapist and wheelchair vendor get together and decide which is best for me. I only get to decide certain basic things such as rearwheel/center Drive/front wheel, color options, not much more. Otherwise, Medicare will not pay for it. They only pay for what is suggested by the physical therapist for medical benefits.

There was no tread on those stock tires so they cannot grab to the grass or whatever and I spend a lot of time in the summer in my yard because it is a fairly large yard. I used a center Drive last time and now switching to rearwheel because I tried it and that helps me a lot to get through things.

they told me those aren't air filled, GRRR! I think foam filled or something. I don't know. But I was originally going to switch to air filled and told them I don't want to anymore, so they said pneumatic, HMMM
