Right now I use the A032Rs on my stock rims (for the racetrack only,) 205 front and 245 rear. I'm still at the stock ride height. The car's looser than I'd like on the track, so I'm about to buy a bigger front swaybar. In case the bar causes me to go from too much oversteer to an understeer condition, I might want to add some front grip with wider rubber, so can the OEM wheels take an A032R tire in the 225 size?

And for that matter, does anyone know if the A032R is available in a 255 or 265 size that will fit on the REAR stock wheels?

 

I dont see why not im running a 225 kumho victoracer in the front on stock wheels.

 

225 A032R fits fine on the stock front rim. With 225/245s on the stock suspension I'd describe the handling as "fun".

I wouldn't bother going any wider (or especially taller) than a 245/45 in the rear.

 

I've run A032's 225 in front, 245 in rear, stock wheels, Mugen sway bar (now unavailable?), stiffer springs (GC perches, 340 front, 380 rear), slightly lowered, stock shocks, X-brace.

Everything fits, nothing rubs, handling is pretty balanced.

Although I wouldn't do A032's again. If I want a longer wearing or streetable R-compound, the Toyo's seem to be the way to go.
