I have 1100 miles on the Rad Rover pulling a trailer weighing 100lbs total. I could have gotten 1500 miles on the rear Kenda tire and 2000 on the front Kenda tire, if not for a broken beer bottle. Most of my riding is road and some state, national park trails. Went with the Vee Tire Company, Chicane. 10 miles in it seems a good choice for the riding I do. The Rad Rover seems faster with these tires? Or maybe it was just not riding for a week while the new tires shipped. To be clear; it seems I can pedal it faster, top speed for each level of assist is the same, just easier to reach. Oh I added a horn and removed the bell, prostate seat, and a washing at 1,000 miles. Its been a great ride, n ot to mention I have lost about 30lbs since the Rad Rover arrived in July.
