About to buy some more tires from you guys, but I'm not sure what size to go with...I replaced the front Super F1's with the 245\45R20 Hankook V12s, but can't find anything "wider" in the Hankook V-12 lineup that'll work in the rear....

What's the maximum size you'd recommend? And what tire would you recommend? I like the Invos, but I'm open to any suggestions, I just really want to be able to plant the power on my SRT-8, it's not supercharged but it just spins the F1's like crazy so I defiantly want a wider tire, but still fill up the rear wheel well right

If there IS a Hankook V-12 that can do that, then I'd much rather get that as I LOVE my front V-12s I do see these sizes but not sure what would look right...tire picking is very new to me
275/30R20XL 97Y SBL 275/35R20XL 102Y SBL 285/30R20XL 99Y SBL 295/25R20XL 95Y SBL

I figured going from a 255\45 to a 35-30 height wouldn't look right but I don't know anything about this lol, I know I've heard of ABS stuff like this "According to the SRT engineers, your ABS will remain satisfied as long as the diameters of the front and rear tires remain within 5% of each other, regardless of how tall or short they are..."

Which makes me think 275\40\20 is perfect, as the over-all diameter difference between the fronts and the 275\40\20 rears is the front is 20.68, and the rear is 20.66 and it still gives me .73 of an inch more tread than the stock 255/45/20's....what do you think?

Thank you for the additional information. Ideally, you would be best off running the Hankook Evo V12 on all 4 corners but as you have found the Evo V12 is not produced in a matching, wider rear size that is ideal for your Challenger. In this case I would first recommend running the same 245/45R20 size on the rear as well. Doing this will help keep your vehicle predictable in handling.

If you are set on running something wider in the rear, the Invo is produced in a 275/40R20. This size would match up with the front size you are running and it would be within the recommended tire width for your stock wheels. Unfortunately this tire is on back order right now with no ETA. I imagine Nitto will start building this tire in this size again soon but I don't have an ETA at this time. When you are ready to order please call us at 1.888.459.4080. Your salesman will be happy to call Nitto in an effort to get the most up-to-date ETA as possible.

The stock SRT-8 tire I have in the rear is 255\45R20 I believe...it's the Good Year F1's fronts are 245/45R20 stock, they are different, would the 275\40\20 offer a good bit better traction than a 255\45\R20?
