Excellent tire.

I put this tire on the front 2 days before heading to Moab for 1 week. FYI I have been MTB since 1995 and tried many tires from old school 1.95 to 3.0. I ride Moab every year. This tire was excellent. Great cornering and traction on everything from Porcupine, Mag 7 and yes even slickrock. Rocks, drops, sand you name it. I have one ride here back in the Pacific NW and so far I love the tire. I look forward to getting the back tire.

GoodYear Newton tire
by Jon
Portland, OR

Tire roasted with 2 weeks of use as rear tire. So very poor longevity. Volume good, traction not great due to fast wearing and sidewalls thin/flimsy for �Enduro� casing tire. Also tore as well I believe with at least 28psi rear. Tire ran on +50 lb ebike, so not ebike rated I would say. Got tire heavily discounted, so not terrible loss, but I don't believe I ever had a tire wear so fast before. Back to Schwalbes and all good again
