Milk doesn’t last forever and neither do RV tires.​

If you think that you’d like a more ‘all-season’ tread design, for use during the winter, for example, talk to your dealer or tire service about this before buying tires.​ here

Try to avoid obstructions like potholes, logs, curbs, and rocks, as the persistent scraping and impact will wear the rubber down.

Before going any further let’s take a look at what the ST and LT tire designations actually mean. more

Here is some additional information taken from a Goodyear Tire & Rubber Company Product Service Bulletin, PSB #2011-13. more

If you do visit some of the RV forums, and/or research the topic on the internet you will quickly surmise much of the debate concerning ST vs. LT tires centers around some of the following issues and concerns: more

Then they are not designed to hold a lot of weight. Also, these tires are designed more for show than they are top perform on the road. With all of that said, there are RV users and towers who have had great experiences with their low profile tires . They claim they get better turning control. [links]

The brand name doesn’t really matter here. What matters is the rating. When you are using a light truck or SUV to pull your RV, you want tires that are rated LT or for light trucks.

Also, you should stay with the stock tire size that came with the vehicle when it was new. here

The smaller tire seems to be the better of the two. There are several reasons for this. First , the 20 inch tire, is further from the center of the wheel, making it harder for the engine to get going.

For LT or light truck PSI, it ranges anywhere between 35 and 80 psi depending on load capacity. There are also different psi ratings for cold and warm tires. Travel Trailer tires can be pressurized between 25 and 80 psi and those levels will depend on the weigh of the load you are carrying.

Not necessarily and the reason for this is that they do not have a lot of flexibility as other tires. Another reason is that there is little sidewall cushion available to absorb impacts. [links]

I disagree. As long as you do not overload the tires, they will work fine. The largest differences between car and trailer tires are: 1) modern car tires are radial while trailer tires are bias ply. 2) Tread pattern on trailer tires have much less traction. They are not meant to drive or steer, just follow. here

The load is not carried by the tire, the load is carried by the air within the tire. Most tire failures are caused by overheating. This can come from overheated wheel bearings, overheated brakes, or improper inflation. more

The passenger tires being radial as opposed to bias ply, I see as a bonus.

Heat Resistance
o The same construction factors that make radial tires more puncture resistant also make them more resistant to blowouts from heat. The steel cables of the radial tire will aid in heat dissipation allowing them to run cooler. The heavy rubber and textile cording of the bias ply tire will hold heat, and so they will run hotter under a load[/B]. For occasional use trailers that are run short distances, the lack of heat dissipation of the bias ply tire may not be a factor at all. Radial tires may be the better choice, however, for long distance, frequent use trailers that will see many highway miles on a regular basis.
