I've been using Metzeler tires since 1988, ME33 front and ME99 rear, and I am getting about 11-13,000 miles on the front, and 8-9,000 miles on the rear. The last rear tire, I tried an ME88 to see if I could get more life out it, as far as I can tell, maybe 1,000 miles more, so not much of an improvement. I noticed the Lazertec rear is a different tread design. Anybody have any experience with the Lazertec rear tire? I'm due a new rear tire on the R65 in about a 1,000 miles or so, the wear bars are close to being exposed.
