Tires

[wheelie207]

Those tires on your home built chairs. I am wondering where you found them as I am looking for those for my chair.
I live in Phoenix Arizona and there are these things that fall off the trees and they seem to have a sharp thorn on them and they can punture tires and cause flats.

Do you mean the reinforced puncture proof tubeless ones called K-Shield? As on here?

That would be a Sweet Gum tree.

Yes burgerman, those ones.
Unless you have tires to recommend besides the k-shield.
I have a F5 front wheel drive permobil and just want to keep from having flats from the small thorny things from trees. Don’t know what they are called.

Its not as easy as just fitting tyres. They need different much wider smaller diameter rims, and the chair will end up 6 inches wider than now unless you completely redesign it and move the motors 3 inches inboard each side. The chair was designed around them.

I fitted TUBELESS stronger build road tyres to my Salsa chair. It now uses 120/70-8 tyres but again that too needs a wider rim. And it made a 24.5 inch stock chair 27 inches wide. So its sort of in between. Wider than stock, but ok for my doors/van. And tubeless tyres are far less likely to deflate even if punctured. They sort of self seal, compared to a tube that rips or expands around the hole. And the tyre seal really does work 100% of the time on tubeless tyres.

RIM very cheap in china, needs an adapter making however. Its not plug and play.

120/70 TYRES (TIRES?) -- (different make shown)

STOCK chair 3.00 X 8 FLIMSY TUBE TYPE TYRES

120/70 TUBELESS DRUG DEALER TYRES! MUCH STRONGER CONSTRUCTION, AND TUBE FREE SO SEALER ACTUALLY WORKS.
BUT CHAIR 3 INCHES WIDER. Was 24.4 and now 27.25.

Then theres these...
130/60-10, also need rims. But these are larger overall diameter by an inch and still wider over the ones above. So need careful consideration needed.

The chair is narrowed so motors are more inboard, to make overall width well under 25 inches. Also strong, tubeless construction. So punctures very unlikely. And all but impossible with sealer installed.
