I don't want too much tramlining/road wander. In fact, I hate that. Additionally, since I run rather high tire pressures, going to a tire that has a -slightly- smaller diameter should help offset the size increasing effects of high pressures.
As for my tires... Well... I rarely drive more than 10-15 over the limit, however, I like to accelerate into corners.
I also usually drive with DSC off. (I learned to drive on a '94 325i 5spd SP, and damned if I need pansy DSC!
) All of these combined factors result in impressive levels of tire wear. The other problem is that the Contis have so little traction that I'm constantly sliding through on/off ramps on the highways and such.
Quite simply, I drive in a rather aggressive manner if, and ONLY if there is space for it, i.e an empty road. I don't do anything in traffic.
I'm looking forward to hitting the wear bars.
