I'm sure this has been asked several times before so sorry for that already, but I don't really have the time to search now because I'm on vacation here in the US.
Anyways, I'm thinking of buying new Rallye Wheels and redline radials for my Camaro while here in CA. I'm going to upgrade one size up from original 14 to 15inch, but I'm not sure whether to go with 6 or 7" wide wheels. What would you recommend and what BS should I go with these wheels?
Tires for 15 in wheel:
My car has 235/60/15 on the front and 255/70/15 on the back, which is what the guy who owned it before me had on it. I just bought the same size to replace the front tires, and when the backs wear out, I'll put a smaller size on there. It makes the car ride a little higher in the back with the bigger tires on there, if you like that look.
I would base the wheel width on the tires you are buying or would intend to use in the future.
I normally go with the 7" as I most often use a 70% or lower ratio tire.
Coker Tire sells a line of 15" Radial Redlines that have a good selection of sizes.
I've used the 215/60R-15 and it looked nice on a mostly 'stockish' Camaro convertible. The rims were 15X7 ralleys, chrome finish.
I've also put a set of the 225/70R-15 on a big-block conversion that built as a driver - they looked good and performed well. When it came time to replace I went down a size or two (don't remember exactly as the tires were just out from Coker) on the fronts and it gave the car a subtle rake and got the front down just a bit.
Summit Racing sells Coker tires (and the rims) and could possibly arrange shipping for you ...
