i have 18in rims with a 40mm offset for my 86 4 bolt rx7 what tire size would be the biggest size i can get on the back and front with and without spacers would like to get some 255's in the back if possible? help me out i need traction fast!

 

i am running 225/40 and 255/35 on 18x8s, 40 offset

I did run a small spacer in the front, I have a 5 bolt suspension with RB springs and KYB AGXs

I think I could have even went wider in the rear

 

going to test fit some tires tomorrow maybe 255/35 thinking if i go anything over 225 in the front i will need an over fender? anyone else have any info?

 

That size and nothing rubs at all? I wanna go 18's too but scared of the NYC strrets.

 

got 275/40/18's on it today in the rear and 225/40/18 with a 5mm spacer in the front looks real mean!!!
