On my Hellcat I ran a Continental Extreme DW 245/45R20 on an 20X8.5 rim. That was the lightest tire in that size that would match the original tire height. You could run that tire on an 8" rim that will save a little more weight 71HB0080W38A They only make an extreme contact sport now which is essentially the same tire I think.Thank you, this is exactly the information I was looking for. Any suggestions on tires to go on the front?
On tire rack web site the specs are wrong. That tire is 28.7 tall and minimum rim width is 7.5 with a measuring rim of 8" Continental ExtremeContact Sport
For that 7.5" rim I would run any of these tires. Just look at the specs and choose the lightest tire you you like the price and look. It's slightly shorter at 28.4" but should not be an issue at all.
