hey guys, I got a great deal on some wheels, and I want to know what the biggest tire i could use to have no rub (I know every car is different, but im looking to be safe)
The car isnt going to be daily driven so im not worried about a little rubbing, and the back seats will not be in the car so it will only have one passenger up front.
The wheels are cragar 5 star 341 series.
Backs are 15x8" with a 4.125" backspace, and the fronts are 15x6 with a 3.5" backspace
I want to fit the tallest tire I can in the back.
I know the backspace isnt the ideal one but I have to work with what I have.. thanks!
I've got the 275/60 - 15s on my 15/8 rear wheels with a 4.5 BS. You won't get away with any less BS than that as when you're high speeding it around a curve the tire will kiss the leaf spring and/or fenderwell.
You can get Gorilla wheel spacers from Summit to bring the wheel out just a bit.
for the front I went with 245/60/15s on a 15/7 wheel 4.5 BS as well. I know I could get away with 4.25 BS but would be tight. You've got 3.5 BS so you should put in a 3/4 inch spacer to bring it out. By the way, my tires rub the frame on tight turns so I have to try and remember to not fully turn the steering wheel. My front springs have a one inch drop...I don't really think it makes any difference.
For the rear I added teflon blocks onto the rubber axle bumper to keep the tires down. Also put in stiff KYB Gas-A-Just shocks and that realy helps so I've had practically no tire/fenderwell conflict. Lots of people remark that my wheels/tires setup are the tightest they've ever seen on the street.
