It's almost time to replace my front tire. I have a Pirelli MT18 front on my bike and have about 3,500 mixed miles on it. I typically run about 22 psi and am too lazy to air down most of the time. About 1500 miles ago I got a flat and so the tire was reversed when re-installed. I'm sure that has helped with longevity. This tire is pretty good off road and really no complaints on the road either. It really bites into the dirt and is ok (not great) in sand. Anyway I'm thinking of either finishing the season with this one or just bite the bullet and replace it before Fall starts and the trails get full of leaves and mud. Hoping to get more miles from the next one (I ride/commute all year) but still be good off road. New England woods are dark and muddy and tight and I hate it when the front washes out. I have a new D606 for the rear. Any recommendations for the next front?
