Arrow 15x7 rallys & tire sizes

Ok - I have read hundreds of posts and tried to do some thorough homework on this subject. This is specific to 15x7 rallys. Looks like the concenses is: 245-60 or 255-60 on the rear will fit under the fender and will NOT rub. 255 looks a little bit out of proportion to me but that's just one guy's opinion. As to the fronts; up to 225-60 does not rub on any car with stock height (decent springs). 235-60 does not rub on MOST cars but does on some. 245-60's rub but some say tolerable. To: you guys with actual experience with these set-ups - do you agree? Can you direct me to some pictures? I like to push my 68 in the corners so I'm thinking 225/60 up front and 245-60 in the rear. THANKS!

I was running 215/65/15 & 255/60/15. I'm sure 225 in front would've been fine, but I wouldn't have done 235. In the rear, some guys run em' 275 and claim no issues. Personally, I think 255 is perfect on 15's for the rear, and either 215, 225 or 235 for front (personal choice).

A lot of this depends on what you're looking for in the way of handling etc... If for handling, less bulge is better. I switched to 17"s a few months ago and have no regret, but this was also in conjunction with a larger plan; front & rear suspension changes.

Bottom line: Your choice above is perfectly sound!

Re: 15x7 rallys & tire sizes

I've got 255 60 15s on the rear, and 215 60 15s up front.
Aesthetically, If I were to change something (and if I were to continue to use 15s), I'd go with 225 60 15s up front.
(I should note, the car has never been driven on the street with these yet)

Re: 15x7 rallys & tire sizes

I have a 68 convertible SS with a 468 BB. The 15 x 7's have worked well for me. I have run 235/60 on the front and 255/60 on the rear for 12 years. The fronts rub when you turn extreme right or left against the frame. You just learn to take it easy when making hard turns.

The car looks good and handles very well.

Re: 15x7 rallys & tire sizes

My car has the hotchkis lowering kit on it.Before I lowered it I ran 235/60's all the way around...after lowering I had to change the fronts to 225/60's and I have zero rubbing issues. I always thought the 235's had a good proportion to the fender well opening without being to obnoxious...just my opinion. But I love the way my car sits and looks with the set up I have now.

Tim, got any pics? Not to hijack a post, but I'd like to see how that affects the stance.

Here's a pic of mine with 215/65/15 & 255/60/15 before I switched to 17"s:



And here's with the change to 17"s and dropped the rear 1.5" and the front 1":



Hope it helps.

I wish I did,
