Many reviews have commented about a lack of good wet conditions tires for plus bikes. Obviously for a lot of you British riders this is a huge drawback.
If you are plus-curious but wanted a decent ‘winter’ tire, look no further than the Surly Dirt Wizard 27.5+.
This is NOT the same tire as the 29+ or 26+ versions.
It has big knobs (center knobs are at least 5mm tall, side knobs over 9mm tall), widely spaced for mud shedding, soft compound and a super strong casing to run low pressures without squirming and to reduce tire bounce, all for maximum control in poor conditions. The spacing is much wider than it looks in the Surly photos. It reminds me of a cut down mud spike.
I don’t work for Surly, just wanted to let people know THERE are options, and the tire has been available for a while, not some vaporware. It seems like every plus review I’ve read lately laments the lack of decent, sticky, sticky tires.
