A lot of people have experienced blow-out problems with the ST tire but I don't know why. The tread is designed to scoot sideways more easily then regular tires for tandem application. I have known people to replace them with regular car tires on their camper, carry 45 lbs. pressure in them, and get along just fine.

Run the other way and don't look back. I have had 6 of those things blow on my 5th wheel Travel Trailer. Now have LT 700R115;s on it and have 4500 miles on the tires [3 years of use]and I keep them clean and shiny with Tire Covers installed and on Jacks off the ground same as I did for the ST tires.Extreme I know but it works for me. will never go back to ST series tires,Goodyear Marathon are no good.

"ST" tires are designed for trailer use and have load ratings the same as "P" or "LT" tires. However they do have a Speed rating of 60 MPH . If you are going to travel at a faster speed than 60 MPH you don't need to use "ST" tires . Go to "LT" tires never use "P" as the side walls are weaker and they will not hold up under a load . I use "ST" & stay below 60 MPH and have never had any problem with them in the 50 years I have used them .
