Am expecting 330 xi w/performance and 162 wheels to be delivered in early February. I want to dump the run flats as they are HEAVY! I am considering the Dunlop Direzza DZ 101, but cannot find much info on them. I'm also looking at Pirelli P Zero Nero and Toyo Proxes T1R. Tire weight is a major consideration. I would appreciate any info or opinions re: the Dunlop tires.......Thanks.
