Does anybody use a 305/30ZR20 (or 305/30R20) size R-Compound tire with a tread wear (UTQG) rating between 75 and 150 (and a symmetrical tread pattern) on the rear of their Slingshot? If so, I will buy you lunch to give me the make and model of that tire, along with your driving impression of that rear tire setup. Thank you. Thank you. Thank you.
