I just purchased a new Grand Designs Reflection 295RL and it came with West Lake Super ST225/75R15LRE which has a speed rating of "L" (75mph)
Just as a video about someone changing to Goodyear Endurance which has a higher speed rating of 85 and some side wall features other dont have. The WastLake tires made in China and the Goodyear made in USA. He only had 3,000 or so miles on the tires and was worried they wouldnt last. 3,000 miles, I do more than double that in a season. I had LT235/85R16E on my other 5er and would run them for 4 seasons or aprox 30,000 miles. So guess I will run the ST's on my new 5er for a year and then go to 16" LT's. Not a big fan of ST tires
