What is the expected tire mileage of 19.5″ Commercial tires?
Commercial-duty truck tires are much more durable than 16″ Light Truck (LT) tires. They run much cooler and use different rubber compounds and therefore last much longer. They are constructed the same way as a tractor-trailer tire and those trucks get considerable mileage out of their tires. With 19.5″ commercial tires, you can generally expect to get 2-4 times more mileage than you will get out of 16″s, and often much more. As with any tire, regular rotation, proper air pressure, and a properly aligned front and rear end are essential to getting the maximum wear out of the tires. Driving style, driving conditions, tread pattern, proper match mounting and balancing, engine enhancements, and the condition of your shock absorbers will all contribute greatly to the longevity of the tire.
