Anyone ever run this tire? i picked up a set of 20" iforged variants, and tire selection is pretty limited. First choice would be michelin pilot super sports but the 345/30/20 is on national backorder. They have toyo proxes T1R in a 345/25/20 with very mixed reviews. Car has 600whp and 1st gear is tough to get traction on my 345/30/19 MPSS. Are the T1r any good? trash? etc
