These have a heavier steel. We drove accross glass at CRA at Vernon about 1,000 times, and never had one flat. Then we put these on, and got 2 on the first. Also the trailer tires were ripped apart on it. That shows a ton for these M310. Also, this is under a different class. These are commercial, not recreational. These tires are HEAVY. 2 times the wheel.
