Wheel conversions: What front/rear wheels still readily available?

[oldktmdude]

Well, myself I´ve always used 120 with the apropiarte front FZR rim, but I know FJowners with 110s and I´ve tested some of these and everything go right

Its true that even the speed index is the same between 110 & 120s, the load index is 54 for 110s and 58 for 120, but 54 is safe enough

So I agree & disagree  

Funny you should mention about the FZR front wheel. They came from the factory with 130/60 VR17 tyres fitted. (3.5" wheel)
  Doesn't seem to be a hard and fast rule about tyre width/wheel width within reason. I have a 3.5" FZR wheel on my FJ and there
is no way I would ever fit a 130 tyre to it. Turn in would suffer too much.

Just curious, Do you (would you) use the AVON AM26 front on a 3" wide wheel on your FJ?

I do and have done for a few years. 120/70/17 Avon AM26 Roadrider bias ply on the standard 3inch front wheel and a 170/60/17 Michelin Pilot road 3 radial on a 4.5 inch rear wheel, so both tyres have a pinched look to them. I'm not the fastest rider by far in our group but I'm not the slowest either, and although I don't think I'll ever get rid of the chicken strips on the pinched profiles, I don't feel it has any adverse affects on the handling. No brown pucker moments so far from either mismatched tyres or pinched profiles.
