I had to go to 18s on the rear of mine to get a tall tire on it, but that was several years ago. I exhausted all of the options that 17s had to offer and couldn't get close to the 295/45/18 that I have back there now.

They are 28.5" tall....a tall tire, to compare, the 235/55/17's mentioned in this thread are 26.75". Also the beloved 275/60/15 is 28" tall.

You won't get everyone to like larger wheels, but you can sure get a lot of them to appreciate the attempt if it's executed well. Tall tires are required to help keep a relative wheel to sidewall height ratio.

For some reference Cuda-Challenger has a very large "wheel thread" that has lots of different configurations.
