LT Tire vs ST Tire

I assumed I wanted ST Tires for my camper and some people are telling me to go with LT Tires. Now I'm confused, and guess I shouldn't assume.

It's hard to discern what it is you may have wanted from this discussion. You didn't provide tire sizes, your trailer's GAWR information or much of anything that would allow posters to provide you with usable feedback. Then after a few pages of information you say thanks and decide to do some pricing. On what?

There are numerous obstacles that must be surmounted to safely obtain replacement tires that do not match the vehicle's Original Equipment (OE) tires. Suitable clearances for the replacement tires to fit into the trailer's wheelwells. For multi axle trailers, sufficient clearances between the axles must be established for the replacement tire/rim fitments. Rim sizes, load capacities and air pressure requirements for the replacement tires must be adhered to.

Trailers under 10,000# GVWR can be fitted with Passenger tires. It's a consideration often overlooked. Light Truck tires are a popular replacement for Special Trailer tires, so are medium duty truck tires for the heavier trailers.

The key to replacing trailer tires is to follow industry standards for such replacements. It's called "plus sizing". There are numerous references found on the www that list in detail just how those type of replacements are made. I'll list one below. Only use the information that applies to your particular situation.

Bottom line: Read your trailer's owner's manual. Ask your trailer's manufacturer for recommendations. Work with a trusted tire retailer.
