This tire’s life in hours equates to 1 year and 18 days of use, but it was not running continuously. Impressively though, it was working around the clock approximately 47 hours a week over the last 193 weeks. This number, 9190.40, is over double a 4,000.00-hour life – which would be considered a good run. According to Bill, 4,000.00 hours are at the lower end of our brand’s average lifespan, and he’s seen quite a few over last 6,000.00 hours. Across the board, Stellana tires been seen to outlast the other tires in the market whether they last 4,000, 6,000 or 9,000+ hours.
