...So you folks that are running LT's on a trailer, did the tire store mount them or did you take all five wheels in and have the mount them? Also when you get in a wreck and the investigating agency sees non trailer tires,,,how will you explain that?? I guess no harm no foul,, as long as nothing goes wrong,, but in my state (CA) I can not find a tire store to put LT tires on an ST trailer?? I had to listen to the owner tell me that if I got in a wreck,, CHP and a good lawyer could find them guilty of mounting Light Truck Tires on a Trailer! Hell yeah I would buy twelve ply tires for my trailer,, but I couldn't explain why in a court of law, other than some bloggers suggested it?? Hard fact is,, tires are well under five years old and are failed.. Maxxis or not.. Only good thing is, I caught it before it cost me a bundle.. Take it for what its worth!!
LT tires are designed to be a steer, drive, or trailing tire. They function the same, if not better, than an ST tire on a trailer. Over the years there's been people who've contacted tire manufacturers over LT tires on trailers and posted manufacturer's responses on the forums. I can't remember one of those responses that said that they forbid their LT tires from being installed on a trailer. The manufacturers never went as far as to outright recommend LTs, but they had no problem with the tires being installed on a trailer. There's even been real life tire engineers on the forums that have commented on it and they do not have a problem with the tires being put on a trailer. They're not inferior tires for the purpose.
While ST tires are for trailering only, there's no requirement that trailers must use them (at least that I'm aware of). The only requirement that I could think of is that the trailer has to be equipped with tires that can adequately support the weight of the trailer. I know for a fact that Discount Tire will gladly dismount an ST and mount a LT on a TT or a 5th wheel.
The legal scenarios get tossed around here often for everything, but we never see them come to pass in the real world. There's tons of trailers running LTs and have for decades. Boat, landscape, cargo, flatbeds, fivers, TTs, you name it. I have yet to hear of a case where someone has been charged, criminally or civilly, for having LT tires on a trailer that has been involved in an accident. Now having bald tires or tires with an inferior capacity is a different story. When we do hear about someone being charged as the result of an accident, it's normally things like missing safety chains, breakaway not working, failure to control speed, etc.
