These tires are fantastic...I took off the off road tires and installed these. My son loves them...faster on the terrain he rides...mostly road with a mix of gravel...Delivery was quick and received on time.
These tires ride great on the street, very little resistance from the tread and at 60 psi you can get going on some hills. They are also better than you'd think in the dirt. I've had these tires on my bike for years, just ordered my second pair finally and that was only due to skidding all the time ,) They are even good in the rain... Get some now, they're the Best!
My kid rides a 24" mountain bike, and I had the hardest time trying to find a city tire to fit it. These Holy Rollers though do a pretty good job. They got his rolling resistance way down, but still give him plenty of bite for whatever trail riding he's likely to do.
