Installed the 7.5"x16" Hartge's w/Contiextreme 225-55 fr. and 245-50 rr. I had questioned the board for opinions on staggering the tires on uniform width wheels and seeing no really good reason not to, I did. No regrets, you can see the stagger and I like it a lot. Would have preferred the 8.5's in the rear but they are NLA (as are the 7.5's now). I had OEM 15" black and chrome baskets and Yoko AVS db2's which were on the car when I bought it and were worn out when I replaced them. I had extreme wear on the outer 2" of the fronts from the high caster BMW dials in and aggressive driving. The new wheels look very good to me, not much "bling" with the painted finish and no shiny lip but a nice subtle aggressive look. The Hartge center-caps add a nice touch and identify the wheels as something a little unique. I weighed the wheels at about 19 lb's and will check the baskets after I strip the tires off to compare.
The conti's were my second choice after the new P-zero Nero M&S but after waiting 3 months on backorder status I gave up. The conti's look O.K. but not great, sidewalls are a little busy and the tread looks a little like a tractor tire but that is the trade off for wet weather traction. The ride quality is improved and the straight ahead tracking is much better probably due to the wear on the Yoko's. The tires just "feel" much better. I have not tackled the twisties yet and need to snap some pics for opinions from the board but will do both soon and post a follow-up.
