Trailer talk: Tires...ST vs LT?

Derick · Oct 18, 2018

So I have a flatbed 12k trailer that I use for misc stuff. It needs new tires. I think they are 235/85/16s. My Burb has some chinese rubber on it right now, which I actually dont mind. The trailer currently has LT tires on it but I always had heard that you are supposed to get ST tires on trailers. I was considering buying some name brand LT tires for the burb, and moving the chinese stuff which is in good condition to the trailer. What's the difference between ST and LT tires, and should I stick with LT tires?

The difference with ST tires is a thicker bead ring and thicker nylon plies, per avg tire size vs P or LT tires. The main thing ST try to accomplish, is not folding under the rim while turning/maneuvering. ST max load ratings are usually way high per given tire size as well.

LT's can work on trailers in the right conditions. Light loads, minimal maneuvering on asphalt and mostly cruising, etc. I would call ahead to tire shop you plan on using, an increasing number won't mount anything but ST's to trailer/trailer rims. My work doesn't.

Interesting...how is that criteria specified? I want to say, I THINK the tire and weight placard calls for LT tires.... Would that be denied at your shop?

We go by what the placard calls for, if there is, or if its gone there's a couple Goodyear/other guide books we have. We won't put Passenger tires on Super Duties/HDs, 2500/3500 cargo vans, etc. I really doubt the trailer placard calls for LT's, but anything is possible. I guess in that instance, we would.
