There may not be a dimes worth of difference between all the aforementioned tires--or maybe there is. Seems like application would dictate the best tire selection, eg, not sure a standard truck tire will satisfy an RV application. The average tire age for a long-haul trucker is probably measured in months not years. Accordingly, a trucker is looking for an economical, high mileage, tough wearing tire, while an RVer is looking for good ride, good handling and UV-resistance[age-out not wear-out]. Can you get both in a single tire at an "economical" price--perhaps?
