Right now I have the ehline durables in 27.5 x 2.5. running them tubeless. I guess I didn't really ask a question. I was wondering if 3000 miles a season on a rear tire on mostly asphalt/roads was worth worrying about. I used to run Marathons on my mtn bike and would get like three seasons or more. But the also sucked on loose gravel. I'm planning on riding more gravel/trail this year but still a lot of asphalt trails/etc.
Not sure how narrow I can go. But the 27.5 seems to be limiting a bit. The ehline and bike were just great on gravel when I did gravel.
