We have a dual axle travel trailer with 13" wheels. On our last trip blew one of tires. I started doing some research and found that these are ST rated tires which I think means they are rated to 65 MPH.Now, I know, I should keep my speed down and just enjoy the trip, but I do occasionally find the need to speed up a bit. I do like to keep up with the flow of traffic. I'd like tires with a better speed rating.Now I did see an ST175/80R13 that says it has an "M" rating, which is 81MPH. But from what I've read ST means 65 MPH. I'm confused.Anyone have any insight?

The ST rating doesn't mean they must be limited to 65 and some better tires aren't.I'm not sure if they make your size but Goodyear makes the "Endurance" ST tire here in the USA and it is rated for 86 MPH max.So far, they are getting very good reviews and I have them on my new TT.

New gen ST tires like the Providers.......Carlisle new HD......and Goodyears new made in the USA Endurance carry a 75-81 mph speed rating. The Providers have been around since the '11 era and have a excellent track record in the larger sizes for commercial and rv trailers. Carlisle HD and Goodyear Endurance ST tires has been out for about a year. They seem popular but no track record yet. When Maxxis first came out they were popular however 3-4 years down the road and they also started having issues......so it takes time.

Like many others, I recently installed a set of Goodyear Endurance ST205/75 R14 on my own dual axle trailer - 8 ply, Load Range D tires manufactured in the US, to replace the crappy 6 ply, Load Range C off shore tires that came with the trailer, one of which recently self destructed.

Can you you use bigger rimed wheels on your RV i.e. 15". ? Would make a big difference.

"but I do occasionally find the need to speed up a bit. I do like to keep up with the flow of traffic."What you "need" and "like" may kill you and others. Your conduct is irresponsible.
