I got a used set of 27.5+ wheels and tires that I've been running on my hardtail. The tires are WTB Ranger 27.5x3.0 tires. They are light, roll well, and provide decent traction, except on roots. I'd like something grippier, but I think something like a Minion DHF/DHR2 would be way overkill. I was thinking of a set of 2.8 Rekons, and wondering if these would give some increased grip without adding much weight and rolling resistance. The rims are 44mm internal, so I think a 3.0 is ideal, but a 2.8 would probably work fine too. Any recommendations for 27.5+ 2.8 or 3.0 tire that would give good traction climbing on roots and rocks but still roll pretty well and isn't heavy?
