Nitto makes some 20" DR's that would fix the issue, those tires would last as much as the best summer tire available in the dry, and you can drive them in the rain provided you're really careful. I drive my Toyo DR's daily. I got tired of getting screwed up at stoplights if you know what I mean

, I painted my stock 18"s in black, and had a set of 17" GTO wheels with the DR's already on, that I was using only for the track. I got tired of switching the rears , so i'm running the GTO wheels (which I also painted black) in the back with the DR's permanently, considering the Toyo 275/40/17 DR's are only $150 each, and wear seems on par with the Nittos, I can't really complaint about wearing them down, and traction in the street is just awesome.
