Default ST vs. LT For Trailer Tires

So need a new set of shoes for the TT and am looking for opinions on which is the best route to go.


Size is 225-75-15 and am not too happy with the options in my area. Really can only fond 2 different tires. Goodride 10 ply load range E or Carlisle 10 ply load range E. Right now have a set of Goodyear Marathon which apart from being almost 15 year old and starting to get too many cracks for my liking and 1 that did crack and now leaks they have been great.


I've heard about people putting LT tires on trailers to increase options and brands. Is this something that would work and perform better then the ST tire or stick with a dedicated trailer tire.....Thoughts??

Check your provincial regulations first, here in Ontario you can only use designated trailer tires.

The ST tires have a sidewall that is made to take the hard short turning radius of a TT. The LT tires have a stiffer sidewall and may not be what you want. It won't hurt anything to switch to LT, but you may not like the way it can handle a short turning radius. I did a lot of research before i purchased a new set of ST tires. The concensus on an RV forum was Maxxis was the brand to choose. I had to get Discount Tire to order them as they are not a normal stock item. The had Carlisle and Goodyear. I heard that Goodyears are made in china, but can't verify that.

I went through the same thing a few years ago. My trailer has 225-75/15 as well. To go to LT, I was going to have to go to 235. They may have rubbed. My TT came with C rated tires. I upgraded to D. I bought Carlisle Radial Trail RH tires. I have used them 3 seasons and have no complaints.

I have been happy with the Maxxis 8008 ST tires, made in Thailand. Rated for 65 mph, but that is fast enough for me. Available in Load Ranges B,C,D. I went up one load range when I replaced the OEM trailer tires.




Goodyear Endurance ST tires are made in the USA and rated for 87 mph. Load Ranges D and E.



Goodyear Marathon ST tires are made in China.

Cool

Goodyear Endurance or the Maxxis 8008 are the ones I see recommended most often on the RV forums.

The internet is flooded with what is referred to as China bomb's at about 1/2 the price of domestic brands. [Many of which are also made in China, Thailand, Korea ETC.] I run them on all of my trailers and as general rule go up one load range from original tires never had one fail me yet in many thousands of miles.
I live and tow out of southern AZ not exactly tire friendly in the summer.

I suspect many of those internet China bomb blowing stories come from guys who never check their tire pressure.

I would think that the majority of blowouts on any tire are caused by this.

Either they are overinflated or underinflated and both of those conditions are dangerous.

You can add tires that are past their service life to that list of problems as well.
