Hey I have a set of 215/70R15 Blizaaks which are still 50% I am wondering if anyone has ever run a tire this big without rubbing.
Basically its 7.7% bigger so when my speedo reads 100km/h I am really doing 107.7km/h. Which since I know about and can caculate.
Heres the stock vrs new:
Stock 185/75r14
Side wall: 5.5"
Diameter: 24.9"
Circumfrance: 78.3"
Revs/mi: 809.0
New 215/70r15 (beretta gt wheels):
Side wall: 5.9"
Diameter: 26.9"
Circumfrance: 84.4"
Revs/mi: 751.0

The back should be fine. The front will rub when hitting bumps or turning into a parking lot etc etc. If you have them, slap them on and see what happens.

You also realize that the taller the tire the more you reduce your FDR.

Yeah they are temporary, I will be buying brand new tires when I get paid next. I have to drive everyday to work and I need to be safe. So costs dont matter but I am broke now so they will have to do.

Ok got them installed on the tires.... They fit on the back.... Not on the front.
They touch the struts. So they wont work at all.
I put them on the rear and drove around and I could hear them making noise, and I was like oh c**p I just wasted $70. But my lugs werent tight enough so after tightening them they work perfectly normal.
So I put my summer GT wheels on which have all season rubber and I left the rears on. I will probobly get 2 new rubbers put on my summer rims in a few weeks and keep the tires (leaking anyways) and then I will just wear down these old winter tires.

Why do you have all season tires as summer tires?
EDIT: Forgive me if I sound foolish, but if you have a 14 inch rim, which is 355.6 mm, and a tire with a sidewall of 70 mm, you have a total diameter of 495.6. As long as that total diameter doesn't change, you shouldn't have rubbing problems, right? For a 16 in (404 mm) rim the sidewall would have to be about 45 mm.
