Schwalbe

These tires are mounted on an ICE Sprint Tour X recumbent trike. My first pair lasted a disappointing 4000km. due to my lack of experience with trike alignment. This new set has way surpassed those tires and I expect maybe 10000km +. They are on the heavy side, but for an e-trike, who cares? I need something that repels thorns, glass and whatever the roads in Japan throws at me. These tires pass with flying colors. I don't even bother carrying a patch kit anymore.

I've been running these tires (40mm) ever since they were introduced and have been very impressed with their performance and versatility. On tarmac, the unique center tread pattern is very fast and secure at high speeds. I often ride them on the road in late fall and early spring training rides.

On our "Cadillac" gravel in Chicago it is perfect for the crushed limestone trails. And even on more gnarly gravel, its side pattern provides enough grip to make those trails manageable (e.g., Driftless riding in NW Iowa, Unbound routes in Kansas).

I've found that the tires are quite sensitive to air pressure so you need to try different levels to dial in the perfect ride.

I didn't realize it, but I got 2,000 miles out of this tire all on the rear. If I rotated sooner I'd likely get more. Tire is supple and fast and does exactly what I want it to do here in Michigan. We don't have a lot of "chunk" so the gravel is smooth dirt with paved sections in between. Races are flat and fast and these provide enough confidence railing 90 degree corners. I run them on 19mm internal rims (despite what the industry tells me) and they pump up to 49mm. There isn't much road penalty as I've somehow taken some paved KOMs.

Picked up a a soft radial to use in PNW conditions. The radial design does what it promises - a very compliant tire but requires much more effort to get it off the ground compared to a standard casing. I still feel the side knobs need a redesign - they're a bit soft and highly siped and while they've not completely let go on me they don't inspire as much confidence as Maxxis or Continental tread patterns.
