I've been running this tubeless 2.3 on the rear for about 7 months. I put about 25-30 miles a week of pretty brutal technical trail and they'll last about 4 months for the rear- durable and tough. I like it for all conditions on the rear. If wet and slick, drop the pressure to about 20 psi and grip it. I try not to ride in peanut butter mud, but otherwise this tread seems to clean itself pretty good as well. I run something with lugs up front..tubeless bulldog or ignitor. I wouldnt trust the tight tread to grip in hard turns up front.
At 1/3 of retail you cant beat em-5 stars!!
