Mounting tyres

[jetjr]

Ive got 6ply Trelleborgs, and when following up on a vibration issue discovered they dont seem to run true, one in particular.

 

Stub is OK as is hub/bearing piece - runs perfectly

 

just seems tyre is mounted poorly or out of round a few mm

 

Possibly wheel is bent, but doesnt explain out of round problem

 

anyone had the same problem?

 

What is the proper method of mounting onto split rims?

Couple of mm won't make any difference as the tyre distorts as it rotates on the rim (the bottom bit, on the ground).

 

I think most owners have their rims machined slightly (on the inside) to make the tyres go on the rim a bit easier. Make sure you inflate the tube slightly/lightly to make sure you don't pinch it between the rims at assembly.

 

The vibration issue will be wheel balance - most auto tyre places can't balance them as they are too small to fit on the machine. Try your local go-kart club (they balance their tyres on the kart). (or get onto the brakes after lift off as most of us do (won't stop the front wheel though))

Are we talking about the old gold coloured rims or the new solid grey ones?
