i was thinking about running the ROH black ice RT rims on my firebird formula, they make a 17x9 that i plan on running up fron with 275 bf goodrich g-force kdw tires. they also make a 18x10 that i want to run 315 or 345 on the back, does anyone know if they will fit on the rims or under the cars wheel wells?

thanks for the help in advance.

18 by 10 should be fine for a 315 tire.18 by 11 will be better.

 

will the 18x10 with 315 fit under the rear wheel wells? and what about up front with 17x9 275.

thanks again

17X9 with 275/40's will fit fine up front. i dont know about the 18's with 315's in the back though.

 

thanks for the help

 

As long as you get a tire with the same height I don't see why it wouldn't fit. So just make sure that the overall height is the same as a 275-40-17...it will probably be around a 315-30-18 or so, but as long as it is the same it should fit without a problem

 

You may have to roll the edges of the wheel well to prevent rubbing the tire over bumps.
