its a great looking tire in person - feels great - its heavy duty thats for sure - rubber is nice - just too bad its just a bit too big i am afraid -

so now whats my next choice - stick with 300-8 - if i can find something or look for 110/90 like BM - is that wider than the stock 300-8 ?

i cant over do it with my stock rims - i was willing to do this 350-8 if it clears my lockdowns -

do you have a link to your tire shirley ?

just curious the specs - i believe this one said 15 inch over all - i feel its closer to 16 inch

3.50 + 8 rim + 3.50 = 15 diameter nominal.
3.00 + 8 rim + 3.00 = 14 diameter nominal.

With tyres nominal means approximate...

110 x 80 is 110 wide (4.25 inches) and 80% as tall. So its 4.25 wide, and only 3.4 inches tall. So a little lower than yours, but a lot wider. And it needs a 3.25 to 3.5 wide rim. Once fitted they dont look big, the old tyre looks small...

When I see 3.00 x 8 tyres they look like toy ones fitted to old lady chairs.

This is 110/80 - 8 download/file.php?id=6147&mode=view
And... download/file.php?id=6144&mode=view
It looks like it should! The grey tyre looks lost!

A 3.50 x 8 is too tall and thin... Esp on a narrow stock rim.
A 110/80 or 120/70 - 8 tyre is lower but wider... Chair sits better tyre works better. But you need wider rims.
But I give up!

i get it for the most part - but i dont have wider rims to work with right now - so i have to work with the rims i have - stock rims - all this time i am getting the feedback that a 3.50 - 8 would work just a bit wider - 1/2 taller -
now it turns out the tire i have here - seems to be more than that - i want to try to confirm this before i return it -

i got the screws out - which was easy after i sprayed it for a few secs - the screws had locktite on them also - but now cant get the rim apart from the foam tire - thats harder than the screws - will take to bike shop today to get them off the rim - then i can mount new tire on rim just to check - with no tube or air etc, - just want to see if i can some how make this tire work - or else i have to return and stick with a 300-8 for now

my understanding was a 350-8 tire should be the same more or less just a 1/4 wider on each side of the tire - which if fine if that were true with the tire i have here - and i like it now -

for now - on the stock rims - any other tires i can use that would fit other than the one i found is this one -

https://smile.amazon.com/dp/B009D2WVSU/ ... IVIJOZZC37

once i get this all done with this chair - then i can move on and see how to get a hub for my chair motor - i wish they sold them on the sunrise site - i would just buy one - send to shirley and have him make it for me

i have to get this resolved for now first -

my 3.50- 8 tire i have here looks much more than 15 inchs - its closer to 16 inches - i feel 15 would have been fine - without fender - but seems more than 15 - this is why i want to put it on the rim first and then side by side again to see if theres a way it will work -

its a long shot but i have to see first before i return it -

You will find your mobility foam tyre is undersized... And less than 14.
And your new tyre a fraction oversized.

Once fitted the difference is small. 1/2 wider and 1/2 taller (top AND bottom!)

1/2 inch taller shouldnt be a problem with fender removed - it dosnt seem as if it will work - looks much taller than just 1/2 inch - i wont be able to actually mount the tire rim on the chair -

i will attempt to just put the tire on the rim - and then place it near the original tire on the chair etc , to see if its doable at least by eye - the lockdowns is the main concern and it may hold me back from making use of this tire -

but will see first - it may just be able to just make it - MAYBE -

i cant find the specs for this tire now - i though i did before and said 15 inches overall

Its 1/2 taller at the top. And the bottom. That lifts your chair. But you have it sitting on the floor... So now its an INCH taller!

You forget theres an axle and a middle.

yes i realize that - the chair will sit taller once the tire is mounted and will be 1/2 taller all around - it still looks as if its 16 inch overall the tire - another thing - would the chair ride the same - sitting a little higher in the rear ?

i will put the larger front casters also at the same time - the same ones i am using now on the 222 chair - will remove those suspension forks etc, and install fixed forks with the 280/250 tire

i would hate to return them if they can be made to work - but if i mount them etc, i may loose the ability to return - and i need more time - i need to be sure because i will have tire liners made for the tire - in order to do that - they need the tire and make it for that specific tire - in this case i need to be sure what ever tire i use needs to work -

then i can ship the tire to have the liners made and then i can finally get it all installed - its a process which takes some time - i hope to get it all sorted out by July the latest - if i get going and can confirm if this tire fits or have to get a different one -

Put a tape measure around the tyre, divide by 3.14 to find real diameter. Let us know.

would the chair ride the same - sitting a little higher in the rear ?


Almost, better/worse? Who knows.

In half hour will post a pic of the rims you need from shirley cheap! And a 120/70 tyre thats 3.3 inches tall sidewall, so 3.3 + 8 + 3.3 = 14.6 or just a 1/4 inch bigger top and bottom. And about 1.5 inches wider.

Ok thanks - but being wider - would that fit also ? wont touch inside motor or frame etc, how much wider will the chair be ?

But i still need adapter hub for the rims :(

dont have that kind of tape measure - it wont be accurate with the one i have - i can try

i get 35 all around the tire - and i measure 15 inches tall now - :|

THIS is an 8 inch rim. Its a true tubeless safe strong rim, so can use a tubeless tyre. You will be able to add a tubeless sealer and a strong motorcycle road tyre. Chances of a puncture are somewhere between zero and extremely unlikely!!!

It is 3.5J meaning its the correct width for these tyres:

Duro tubeless, 110/80 or 120/70.
The 120/70 is just 14.5 diameter. And is wider, so looks better, and rides better, and grips better. And wears slower, and is less likely to sink on grass. This is 1.5 inches wider than your 3.00 tyre. It will make your chair 3 inches wider.

The 110/80 tyre is 88mm sidewall (so a little bigger but still less diameter than your 3.5 tyre is very slightly. It will make your chair 2 inches wider. (One each side).

Neither will hit anything as you just add washers if the wheel is too close to the motor.

110

Stupidly cheap from china, and shirley (thanks) or ebay at 3x the price. I bought 4... 92MM PCD, BUT EASY TO DRILL ANY! CLICK!

those look great - cool etc, - but 3 inches wider - too wide for my chair - its already 25.5 width and i feel it going from the 222 chair at 24 inch width to this chair - i feel its a bigger chair -
dont think it will look good that wide - - one inch maybe not too bad -

trying to remove those foam tires from the rim - wasnt happening - i got it done at the bike shop today - and of course it got scuffed up a bit in the process

wasnt easy to remove i was told - - so now i have the tires off the rim - i measure it to be about 2 1/4 inch wide rim -

i think the best bet maybe for me for right now with these rims is to just get the 300-8 tire i found - and return the ones i have here -

the 300-8 tire says its 14.5 inches tall - which is still taller than my stock tire - i measured it at about 13 inches - not 14 x 3 as they all advertise them to be -

i measures the stock tire rim before it was removed all around - it shows 31 inches - with the new tires it showed 35 inches - big difference there -

will take some pics when i get a chance of the rims etc,

maybe the best size rim is a 2.5 for me tubeless - with a tire that is not taller than 15 inches overall -

when you talk about easy to drill etc, - that is not something i can do - and dont know anyone who would - so in my case - i need a setup that is as close to plug and play as it can be - meaning

the Rim maybe i have to stick with 2.5 inch - and use 110/80 tire - if its 14 to 14.5 inches maybe its the best choice tubeless is fine - great - i just need someone to mount without scuffing up the rims -

need a real Car tire changing place - - but first and most important i need a hub to get an adapter made for any new rims - dont think i have this done by this summer -

i like to just get a tire on my stock rims for this summer and work on the real setup hopefully for next summer -

its already 25.5 width


So thats with 3.00.
The 110 tyres are 4.25 wide. So 1.25 inches wider each side. Your chair would be 28 total. Same as an X5.

that sounds too wide for me i think - 28 inches - i think chair will look funny also maybe - this is stressing me out now -

a few more pictures - one has the Old Tire on top and you can see the new tire on the bottom

one near the chair again - but i forgot - since its not on the chair - its not correct either - i cant continue unless i decide what to do with this tire now -

Fit them. You stress too much! Stop fussing and worrying and get them fitted!

The fatter tyres, LOOK huge the day you fit them. Its all a matter of what you have become accustomed to looking at. Worn out undersized mobility tyres... After a few days its the opposite. Every other chair with tiny mobility tyres looks like an institutionalized cut price old peoples push chair. Bigger tyres are just better.

Better for range, better for ride, better for rolling resistance, better for looks, better as they are constructed for non mobility use! More floatation. And LOOK better. And stronger. Better for everything.

Fit them, they WILL fit, then tell us they look bad in a week. Your rims are too narrow, but they will fit. But be a bit squashed in towards the centre making them taller and narrower. At the very worst, you might have to add some washers behind the wheels bolts if the tyres touch anything on the chair inside.The tyres I use are huge compared to those you have!

i dont mind that they are big - i want that - well its not that simple to just mount them -

this was and still is my Plan -

1. Get the tires -
2. Get tire liner made for the tires i will be using -
3. Get all the items i need - Tire - Tire liner - tube and slime -
4. bring it all to the Bike shop to install everything
5. I get them home and just swap it out -

BUT it would be a huge waste of time and money to do this with a Tire i dont know for sure will fit at all -

and if it gets pinched and squeezed like you say - will be even taller -

it may look better if i tried with the 300-8 tire first ? i should have just ordered that one instead if i knew it was going to be this much trouble

https://www.amazon.com/dp/B009D2WVSU/re ... IVIJOZZC37

this one should fit the rim better ? and look nicer because of it - just wont be wider than what i have now - or maybe it will a bit -

i have a better chance at making this work i think ?

i cant do the work myself - so everything will have to be done for me - time money etc, - thats fine if i knew it will work and all i do is install it on the chair -
its worth it - but if i do all that and then it dosnt fit - i have to do it all over again and cant even return what i have - i have to think about that -

i may be able to return it now - but once i start mounting etc, - its a done deal - cant return then - - maybe i hang them on the wall to remind me :mrgreen:

Stop fussing!

Fit tyre. Fit wheel. If the tyre guard gets in the way file it under b1N. Or space it up...
If the tyre hits the chair or motor add a few washers. Done... You dont need a liner. Tyre is stronger than mobility rubbish. You can fit that tyre and tube in your hands. Easily! No force needed.

i worry about the tire since i ride very far with this chair - you dont think i need a liner to be safe ? i will add slime either way

dont think i can do this myself or my girls - i can try maybe - - what size washer do i need in case ? i like to have them here ready

the fender is going to have to come off for sure - that i know - more concerned about the lockdowns that i have the charge cable on - that dosnt move at all its welded

just remembered - i dont have a tube for them - i didnt get one just in case i didnt use this tire - - but if i am try it - i need to get a tube now - and forget the tire liners ?

maybe just get them done for the front caster wheels ?

Tire liners? But the road tyres are tough. Highly unlikely you need liners. Cause more problems than they are worth. Dont use slime its rubbish. Get some off road sealer it is far better and works fine on our slow equipment. Washers? Same size as your wheel bolts. To go behind the wheel in case you need to space it out by 3 or 4mm.

Ok i guess i will give it a shot - just ordered the tubes - its either going to work or i loose out on this set of tires and move on -

i never added the slime myself - to do so - remove the Pin of course - on a empty tube ? i would think and just let it flow in the valve ? when done remove and put the pin back - fill with Air ?

i hope my Air pump Electric has enough power to fill it with Air with the Slime in there - whats a good starting point 30 PSI ? for rear

Hey Shirley - Look what i found - would this be what you would need to make the adapter for a new tubeless rim ?

i never though of looking for it on the website - went to check for washers and noticed the wheel hub -

https://www.quickie-wheelchairs.com/rep ... -s636-s646

#5

i could buy just one of these and thats all you would need ?

went to look for washers and found the hub instead :)

OK then - i will order this Hub - i need just one to send you ? and then when you get a chance - look for some rims etc, - now i am not sure i want to go too wide - because the chair may look funny at 28 inches wide -

2.5 inch rim ? if there is a 3 inch maybe - but i see only 3.5 inch - when we get to that point - we have to figure it out and find a few - but it would be plug and play afterwards ? i would just take the new rim and bolt it on my chair -
nothing for me to drill or do - i wont be able to -

i will give the tires i have here a shot - take a gamble and see what comes of it - its either going to work - or i lose the bet and ebay them for half cost - i think i will send in my front tire to get a tire liner for that one at least - makes me feel better in my head :)

Thanks - curious to see how this will end up

Let me ask you this shirley - Would you be able to order this part for me there ? then i wont have to ship it to you - i can PM you my chairs serial number if thats needed - Let me know if not i will order it here then -

Just an though now that it may be possiable to do a tubeless rim tire combo once the hub is sorted out which i can get now for Shirley - i wonder if i should just Abort what i doing now with the current tires i have and just wait for the new rims tubeless set up - most likely wont be all sorted and ready till some time next year - :idea:

another decision now i have to make :|

Actually , I can access a 646 2-pole model here, and can take the hub away for a while , to accomplish your project ! .

However , I am not sure if it were the same as yours .

Could anyone confirm this ?
