I went for a road trip shrotly after I switched from my Dunlop Wintersport M3's to my old PS2s with 5K miles on them. I rotated the PS2s front to back when I made the switch. The side-hop was <b>terrible</b> on the highway, even in sport. Much worse than ever. I just checked with a tire-gauge and have inner tread depth on the rears of 5/32 and 6/32 in the middle and 7/32 on the outside. Wear is even on the fronts. <p>Possible indication of improper toe-in alignment? When I got the bushing fix I asked the shop foreman to make sure they did the R specific toe-in, but I never saw the alignment spec sheet. Should I spring a hundred bucks for a new alignment just to be sure before my next road trip in a couple of weeks? At this rate I will chew threw the PS2s in 10K miles!
