Hey Jazz,
I think you need to check this byself
I drive on 12" wheels 335/35 ZR18 but I drive Veilside arches.
285 are a good size normaly for 10" wheels but If you need to strech the tyres a little bit 285 will be fine on 12"
If the 295 doesn't scratch and the arches you will be fine
Bigger is better
You don't drive an underpowered car...
Cheers
Peter
