Fitting solid front tires.

[terry2]

Hi all.

I'm sick of getting punchers as I use the roads 90% of the time.

So I bought some solid front tires. I took apart the rim, which comes in 2 parts.
Now this is where I have the problem. The rims fit very well.
But there is a gape of about 1/2 inch, so the screws don't fit to pull the 2 part rims together.

Is it ok to use 2 G-clamps to squeeze the rims together so I can get the bolts in?

Thanks

[terry2]

Looks like it posted twice! sorry

[greybeard]

Either clamps, or better, a couple of longer bolts to bring the halves together. Then fit the proper bolts in the empty holes, tighten down and remove the long bolts. Replace them with the correct bolts. Some diluted washing up liquid on the rims will help.

there are differnet infill widths if you have one that is too fat you will bust your rim if you try and tighten it.

puma 40 should be a 48mm total width iirc but you can get 38mm and 58mm versions

It's 62 mm inside measurement. So to big? Grrrrrrrr

Will have a look on ebay....again.

Thanks for the info Rover

Nothing on ebay...****

[terry2]

I have emailed 6 people telling them I need 48 MM infil width.
Lets see.

Sorry. yes castors.

So the 62 mm ones are still to big or take a chance?

Terry, why not put some OXO Tyre sealant in your castors? The only problem with solids is you're likely to get castor shake when going fast, so be aware of that.

Thanks Steve
I use tires with tubes. And the last puncher was caused by a some metal that made a gash in the side wall of the tire

If I find the right size solid tire I will post the link here.

It will steer worse and eat more battery. And ride harder. Wear out faster.

Dam and blast.
The dual track roads by me have a cycle path which I use all the time.
It's when I reach a part of Birmingham that the roads are dirty with glass\metal.

Just bought some tires\tubes off ebay. They will do till I sort something else out.

Been trying to find new rims for both back and front. But no luck as yet.

[Burgerman]

Define new rims.

These? viewtopic.php?f=2&t=7455&start=600#p122818
Shirley, eBay, monkeybike suppliers, etc. 3.5j x 8. But you will need to make adapters to fit them.
Front? Many options. But all pretty much the same. And will need you to adapt/fit spacers etc.

I really love those back rims.

What is the size of them and did Shirley get them for you? 3.00 X 8 ?

[Burgerman]

3.5j x 8 rims.
120/70-8 tyre.

Thank you.

Can you tell me where you got your rims from please.

[Burgerman]

Yes. Mine came from shirley as price was right. I ordered 4.

Also on ebay, and on monkeybike sites etc.

I am going to get another salsa with lift, tilt, 4 pole, 120A, recline, power centre footplate, lights, advanced colour joystick and single post arms, wide arm tops (P shaped jay ones, etc etc. before they stop selling them, so need the other 2 for that one. One chair no good, you need a matching set. Both in non available custom black with 210Ah lithium...

I've got sealant in my tubeless, luckily I work for a bike distributor that distributes it. Difficult bit was calculating how much, had to pass that to our designer/engineer team. They came up with 350-400ml I don't know how that compares to anyone else using sealant in a 120/70 x 8 tubeless?

[terry2]

BM are these the same as yours?

[Burgerman]

No those are 2 pressed halfs. No use for tubeless tyres. You need cast machined tubeless rims. As per my pic. And you need the 3.5 wide ones as the thinner ones are much harder to fit and do not look right.

Though not the same, exactly

I had a solid tyre come off plastic rims
I separated the the the two halves of the caster wheel, only to find I couldn't fit the tyre back without force
I cut some ply 3/4 around the tyre and used it as a solid base to pull the tyre back into place

Then used longer set screws to pull the rims together, then replaced with the original shorter set screws

you may well have to use longer bolts to pull them in then replace one by one but should not really be more than a 10mm gap to pull, the forces are quite high and having a rim split is not fun. more than the 10mm gap and you have the incorrect size infill in my experience

Thanks again.

I don't think I want to risk breaking the rims.
I will keep looking on ebay to find some rims\tires off a Puma 40.

I have used "Slime" in fill tube sealant in tubed tyres, though I did find I would have to carry spare shrader valve cores. 8 oz bottle for the 18" powertryke tyres. Use 4 oz for a caster tyre and "Slime" tape on the inside of the tyre.

I looked in there for the exact specification of the tyre used on the caster, then in Sunrise's other specification sheets. Found nothing about the tyre PR/Ply rating. Found some replacement pneumatics for the PUMA 40 but they didn't show ply rating. So I ordered a pair, I can always use spare caster wheels, they arrived today.
They're a 2 PR, the bearings are crap and don't bed properly in the wheels. So I contacted the supplier and then went and bought a pair of 4 ply tyres from mobilitypitstop. Couldn't find a higher rating except from Mack GMBH but then I need to order at least 8 tyres (as they're for their river mountain ride)
