Status: Researching summer tire options in anticipation of an early spring. This year, I'm going to get a pair of new 20x9" front wheels to match the 20x10" rear pair I bought last year that are currently sitting in my closet and wearing some very sticky yet very cold-weather-unfriendly Toyo Proxes R888s.
Now while there's a lot to like about the R888, it's treadwear 100, meaning only about 10-15k miles before tread is gone, and the tread pattern makes it very noisy for a daily driver. So I'm trying to find something a bit more streetable without sacrificing too much performance.
One annoying challenge is that tire companies will sell sizes that fit the front 9" wheel with the proper tire height, but won't fit the rear 10" , or vice-versa. That rules out interesting contenders like the Nitto NT05 and the Hankook Ventus RS-3.
Helpfully, a few of the major tire companies are coming out with their next generations of performance tires this year. Continental introduced the ExtremeContact Sport which has matching front and rear sizes, and there's always the gold-standard Michelin Pilot Super Sport. Toyo is also now offering the R888R, which is supposedly much less noisy (to meet new legal standards). So while there are a few dead ends, there's also a decent amount of choice.
Ultimately, I need to call up the tire shop that sold me the R888s, as they'll probably have some other suggestions. The owner there is always a pleasure to work with - in his own words, "This is the stuff I live for. If only I could sell tires to muscle car guys all day instead of (sobbing) Toyota Camrys."
Also, who had the bright idea of putting NT05R drag radials on all four corners of the Hellcat Demon? The first rainstorm on the highway is going to put that thing sideways.
