what is the largest street tire that i can put on the back of my car? stock ride height. i use mt et streets for the track getting ready to buy some new street tires wanting to put the tallest, fatest tire i can put on the back without rubbing. and probly a 165 r15 on the front. also what size backspace do i need for a 15x3.5 weld prostar?

 

anyone?

 

First...........WELCOME to the board.

You can put a 275 50 15 on the rear and maintain the stock height (they are 25.9" tall). They will fit a 7.5 - 9.5" wide rim.

For the 3.5" go with no bs or minimal.

 

I got 295/50x15 for my street tires, it keeps the car at a good height.

 

the only smallest backspace i can find is 1.75 ive heard that on the 4th gens you have to run spacers because they hit the calipers does that hold true to the thirdgens as well? i was also wondering what size rear wheel should i run and what backspace? i like the idea of the 295's do they rub anywhere?

 

15x10 rim with 5.5 backspacing, 295's are a tight fit, but no rubbing

 

anypics? did you have to roll the fenders? and its a 295/50/15?

 

Rolling the fenders would be a good idea with any tight fit tire, but it's not needed. I only have one pic recently but it's not of the rear tires it's just a general shot. My street tires are dunlop gt qualifiers, not the stickiest out there but I don't need to be spending a lot of money on sticky street tires, that's what slicks are for.

 

does anyone have prostars or draglites up front 15x3.5 and did you have to use a spacer or grind a the calipers?

 

on a thirdgen with factory brakes, you dont need spacers..

 

ok good what is the biggest tire you can fit with a 15x8 4.5 inch backspace?

 

275/60-15 its 28" tall

 

I have 8.5 inch wode convos, i have 295/50/15 and they work great, no rubbing, i do have rolled fenders. They ride a bit loose in the rear buy that is because it is not a short side wall, they are BS tires too, nothing special.

 

1.75 back space will fit fine with no spacers. I have them on the front of my car.

 

you can fit a 28 inch tall tire on with stock ride height? i thought it would rub.

 

i'm running 28.5's with stock rear springs.. it only rubs when i launch it hard..

 

My 275/60/R15's are 28" tall and fit fine on stock ride height without rubbing. On 2nd gen snowflake 15x8 wheels.
It needs the fenders rolled though, it slices the sidewall sometimes.

 

what is the backspace on yours?

 

on a forth gen i have seen that you can put on a 15x10 w/ a 5.5 inch backspace and fit a 325/50/15 with that work on a thirdgen or is it way to big?

 

Think it is a 4.5 BS.

 

i ordered my prostars monday they all came in one of the rears was damaged so summit is sending me another one. i bought 15x3.5s up front with 165/80/15 kumhos, and the rear i bought 15x8s with a 4.5 bs. as soon as i can get a set im getting 275/50/15 mickey thompson et street radials for the back. everyone around is out of them because of the world street nationals.
