Goodyear Endurance ST205/75R14 tires
My 2018 Forest River Wildwood X-Lite 254RLXL travel trailer with a GVWR (maximum legal total weight) of 7,668 pounds rides on four Goodyear Endurance ST205/75R14 tires (Load Range D, Max Load 2,040 pounds each, 2,040*4=8,160 pounds), Speed Rating L = 75 mph, Max Cold Pressure 65 psi) with TPMS sensors mounted on each of her four road-tire metal valve stems. In the Fall of 2018 she completed a 2,000+ mile tour of New England and Southern Canada with no problems. In retrospect, perhaps I should have jumped up from Load Range D to Load Range E, but the Load Range D tires are in theory more than adequate for my trailer's GVWR. From what I understand of the Goodyear spec sheet, to get Goodyear Endurance Load Range E tires, I would have had to jump up to ST225/75R15 which would have meant five new wheels (going from 14" to 15") in addition to the cost of the five tires. So far, I'm quite happy with what I have.
