I'd like to fit 18x10s with 275s all the way around. OE Wheels has cobra r's that are 18x10 with a 42mm offset. Just wanted to make sure this will fit before I buy. I remember seeing a couple guys with either 18x10s or 20x10s all the way around but don't remember who and what the offset was.

 

Boy, I know the S197 runs a 9.5" wheel all the way around on the Cobra, but will get crowded up front to run a 10" wheel. Hear told, it has been done and off-set is critical to avoid rubbing up front (not quite soo much in the rear)

Shelby Mustang GT500 wheels

These are +50mm off-set 9.5" wheel, so I would NOT go +42mm on a 10" wheel and expect it to fit well, as I just don't think so. Your proposed 10" wheel is going to be a bit over 1/2" closer to the fender and tire would be nearly 1/4" in addition to this! The GT500 runs a 255 up front, so would be a bit "thin" on the wheel so really helps with clearance.

Bottom line, I would not go with that wheel unless OE Wheels GUARANTEES fitment of that tire/wheel combo both front/rear on your ride.

What Jazzer said. We can't guaranatee the 18x10 in the front.

Whatever you decide to do, make sure you send us pics when you get them on so we can put it on our website.
