i got a smokin deal on some 275/60r15 cooper cobra tires. will they work ok on my 15X7 rims? they are currently mounted on 15X8's.thanks -art

Just checked TireRack.... that size is approved for 7" to 9.5" rims (with 8" being the one used for measurements). So yeah, you'll be OK with 7".

GREAT, thanks

If memory serves, the cooper cobras are very wide 275's (no 2 companies make them the same width, even though it is supposed to be a standard measurement). You may find them to be a tic to wide. They'll 'balloon out' a bit and may make handeling a bit 'squirmy'.

vasquezmrysvll · 04-28-2011, 10:15 PM

interesting, anyone else?

Good memory, Andy. I looked it up on Cooper's site, and their approved rim width for that tire is 7.5" - 9.5".

That said, I bet you could still run that tire on a 7" rim with little to no issues.

the rims that came with the tires are 2 15X8 and 2 15X10 . im gonna break them down and mount them on my 15X7 set and go from there. may end up scrapping the aluminum rims that the tires came on. cant really see someone buying a mismatch set of rims?

Factory 90-93 454SS trucks came with 15x7 wheels and 275/60/15 tires right off the showroom floor. It's a good combination.
