100/90's on AF rims

[MickYork]

What's the thoughts on putting 100/90's on AF rims, would they be ok ?

I have.... No problems other than the 'usual' need to go to AF or find local tyre fitter you trust and who is prepared to faff about to fit them

Depending on tyre brand (rolling size) it may up your gearing slightly. But depending on setup etc it may not be a problem. That’s the only difference I’ve found using that size.
