ST tires have much stronger side walls than LT tires and are designed to hold up better under the twisting that happens to trailers while backing that the truck's tires will never experience. If LT tires were better for trailers, tire manufactures would not make ST tires at all.
Everyone is entitled to their opinion here; just not their own facts.
Facts are that ST's do not hold up as well as LT's do. If your TT weighs more then 10,000 LBS and you ever drive over 65 MPH then you have 4 bombs behind you waiting to go off. I'm ok with using ST's on my flat bed car trailer but you would never see them on a camper.
- All "ST" tires have a maximum speed rating of 65 mph.
- As heat builds up, the tire's structure starts to disintegrate and weaken.
- The load carrying capacity gradually decreases as the heat and stresses generated by higher speed increases.
- With all the chemicals used in ST's to prevent damage from weather they basically disintegrate the load capacity from the heat every mile you drive.
You can say whatever you want about Forest River or any other company, about how wonderful their quality is. Truth of the matter is that every RV company uses ST's because they are made in bad molds and are a lot cheaper to purchase and keep final cost down. Most brand new RV's come with tires that barely go over the MAX weight of your camper. Once you start throwing in all your supplies, extra tv's, pictures, clothes and everything else you need, YOU ARE MORE THEN LIKELY OVER WEIGHT!
All I can say is to go out there and do your homework before you decide what tire is best for you. It is a pretty pricey investment that you want to last and not damage your equipment or hurt your family in anyway.
