You didn't state your intentions, so I will answer what I think you want.
If your intent is cosmetic (looks) then limit the tire tread width to about wheel width (7").
For track usage, the wheel/tire combo will always work best when the wheel is slightly wider than the tire (giving the sidewall more support).
For track, first get the stickiest tire compound (a soft slick, for instance) and one with a short sidewall relative to the tread width. This will give better turn-in. The idea is to develop traction with the tire compound, rather than tire footprint, IF you are limited by tire width.
Hope this helps.

C1 or C2? Rim diameter and backspacing?
If you're asking 15" on a disc brake C2, you'll have trouble fitting that tire in without trimming fender lips regardless of backspacing. 235-60s fit with a 4" backspacing if you tie the parking brake cable to the side of the trailing arm. Expect any of them to rub the frame and sway bar at full lock in the front.
There are some good links in the FAQ post.

C2 car...in the C2 parts for sale section I was thinking of buying the AR rims/tires that are for sale. They are 15"x7" rims and 215's. I would eventually put on larger tires 245's) but not sure if I would be able too. Looks unlikely now that I think about it. Normal street driving..no racing.

Since tires are the single most important factor in suspension tuning, if you find a tire with a clear advantage, I'd tune the suspension to capitalize on the tire. I have run 255-50x15 Hoosier street TDs on 7" rims with fantastic results.

I'm running 235s on 7" rims, American TTIIs. That's as wide a tire as I would want to put on a 7" rim, and about as wide a tire as would fit under the body without flares. A 245 should be on an 8" rim.

I agree with this quote. Since you (again) didn't state your usage, I will (again) mention that the tire compound is MUCH more important than the size!!!
I WILL ELABORATE..... Hoosier 225-60X15 will be a MUCH better tire for you (IF) you drive less than a few (3000 or 4000) miles per year.... in the DRY!!!, than ANY size of street tire!

I meant to mention that the selection was for competition only. I see I missed that point in the post. I'd never run that set up on the street...
