315 on all four corners bastard

 

Do 315s fit on 10 in rims?

 

they will fit, but your contact patch may be hard to optimize (might round at the pressures you need to keep the sidewall hard).

 

I would not recommend mike , My 295's were perfect on a 10.5 . . . a now a little pinched on a 10" wide. I would put 315's on minimum 11" width to be optimal as your adding another 20mm's . You will end up pinching it down and bowing it up to the point where a 295 will have a better sidewall and overall contact area or youll have to run really low pressure to get it flatened out . . . in the end the 295 will feel tighter on a 10" wheel imo and save you some rotational mass .
