Cost per hour is the only number that matters
Two identical tires on the same machine can differ by thousands of hours depending on pressure, load, haul road condition, speed and how quickly damage is caught. That spread is wider than the difference between most tires on the market.
Which is why a program beats a purchase. The levers that move cost per hour are inspection, pressure discipline, repairing what is repairable and retreading sound casings. Changing which tire you buy moves it least.
