I respectfully disagree Leo. Commercial trailer tires are speed rated, just like a passenger car tire. If properly maintained, a commercial trailer tire is good for well over 100,000 miles. A 16 ply trailer tire, which is all that is used in heavy haul and specialized applications, can last even longer. And that is carrying loads in excess of 40,000 lbs on a daily basis. Air pressure is key, especially in the hot summer months. Very rarely do I ever change a trailer tire because it is worn out. Usually it's due to a blowout which I can almost always trace to a foreign object or a tire defect.Almost no rubber is used in modern tire making. Mostly petroleum based synthetics. Commercial trailer tires are not designed to go Passenger car mileage. They are designed to carry a load and not at high speeds. Different application. Like comparing a diesel engine to a gasoline engine.
You can exercise and stay out of the sun, watch what you eat, keep lean and you will still die when you get old. You can stretch it out a little but you can't last forever.
