i will be using a 4th gen offset wheel with a 2 inch spacer and the wheels are 18x 9.5...very doable?

 

i have a 295 35 18 on a 9.5" wheel and thats pushin it.. i think you would have no chance gettin a 315 on that wheel

 

what series is the 315 you want? ie, 315/40/R18?

 

yeah. 315 is def pushing it. If you do the math 315/35/17 wants to be on an 11" wide rim. I stuffed 335s on an 11" wide rim, just cuz i had the tires. I need to get some 315s. Just get what fits right. You will be happier in the end.

This all comes from experience. And believe me I am OBSESSED with w-i-d-e tires.

 

if i get a 11 inch wide rim what kind of back spacing do i need for it to fit in the rear and wht size spacers.and what tire do you recomend its a manual trans mission.with a 496 big block.around 500-600hp. And from time to time a 200shot.

 

tires depend on what you wanna do with the car. Drag, auto X, street. Any kind of wet driving? or even sorta coldish?

Go to tirerack.com they have some good reviews of tires and recomendations.

I just got some 4th gen offset rims and used 2" spacers.

(ZR-1s)

 

the tires will be for drag racing at the track and then for cruising the tires are m/t street legal tires.also the zr1 rims are 11inches wide and a 2inch spacer and then im good it wont buldge out goofy looking?

 

look through my site for a lot of pics and u can judge for yourself

 

i'd go with a 315/35/zr18


acording to a site i was on a while back 9.5 is the smalled you can go for a 315
