Over 300,000 TT and 5vers sold each year for the last three years, or more than 3 million tires. What percentage do you see on the road side, and of them how many were punctures, underinflation, or other road hazards.
I have never seen the hard numbers on the failure rate of P, LT or ST tires; just a lot of rhetoric.
I have also never seen a tire company advertising in the RV or Trailer magazines that you should replace those dreaded ST tire with their superior LT tires. It seems they would rather loose sales.
Maybe I am not looking in the right magazines.
