TransEagle ST Radial All Steel Premium Trailer Tire - ST225/75R15 121/117M F (12 Ply)

Another person mentioned these are like semi tires. That is no joke, they really are. Given that these tires each weigh a lot, if they are out of balance by even a small %, they will cause a lot of shimmying. That is why I paid the extra $5 each to have them balanced. I have done 70mph on the highway with an unloaded 6000lb gross dump trailer with zero vibration from these tires. I can load 2 yards of damp topsoil into the trailer and the sidewalls barely budge at all. The tires that came on the trailer would have been bulging a lot. They were under rated for the gross weight of the trailer with a rating of 2750lbs (or close to that) per tire IIRC. I have only had them for a few months and have hauled about a dozen loads with them. No issues so far. Worth the money.

Perfect tires for your boat trailer

These are the best tires money can buy. Skip those light duty tires and go for the best. Fuel economy of tow vehicle was improved. I put a set of these on my 24 enclosed trailer. Also on my car trailer. I would put these on any trailer I could. They are awesome!!!

My damaged tire took a nail on the outside edge which is not really supposed to be repaired, and so I bought this new one. This new replacement tire took too much weight to ideally balance it, but with added weight it got balanced. I'm not happy about that, but on my initial purchase of four, one was like this. We went through a lengthy replacement process that took three months. I didn't want to do that again. They're very heavy and stiff with more rubber in the side walls and tread than you might think. If you hit a pot hole your trailer springs have to take all the force because the tires don't flex at all. The trailer will shimmy if the pot hole or bump happens in a bend in the road. They are probably too stiff for our 25 foot arctic fox. They require 95 psi and as is the case with all trailer tires they absolutely have to be set at max pressure. Now I am concerned that my wheels might need to be replaced for heavier duty ones due to the very high PSI. I'm not sure if I made the right choice going from an E rated tire to thus F rated tire that acts like a G rated tire. It's probably overkill, but I've always been afraid of getting a blowout that might cause an accident. But, though a heavy tire can easilly still take a nail, I do feel safer with them.

Have had many trailers and have bought many sets of tires... These things are rock solid. The lip alone is 1 inch thick. 12 ply for a RV for the win. If you go to Goodyear endurance that are only 10 ply and you pass these up which are 12 ply, you are missing out.
