Factors to consider when selecting trailer tires

How much weight you are hauling

Remember to consider not only the weight of your load, but also the actual weight of the trailer. Divide the total loaded weight by the # of trailer tires. Once your calculation is complete, you should look for tires that exceed the maximum weight of this number. Trailer tires are rated for a maximum amount of weight that can be transported at maximum air pressure. For example, if your maximum load is 4,000 lbs (including the weight of the trailer) and your trailer only has two trailer tires, the tire needed must exceed 2,000 lbs of load carrying capacity per tire in order to be sufficient.

The load rating of your trailer tires.

Most trailer tire sizes come in several load ranges including LRB (4 ply rated), LRC (6 ply rated), LRD (8 ply rated), LRE (10 ply rated), and LRF (12 ply rated). The heavier Load Ranges will offer greater load carrying capacity, but will offer a stiffer ride and most certainly a steeper price tag.

Trailer tire wheel load capacity

Make sure that the wheel (rim) used with your trailer tires has an equal or greater load carrying capacity to the tire. Selecting a wheel based on price is not always a good choice. Selecting a wheel that offers greater load capacity than the tire is a much safer choice!

Why do trailer tires fail?

The last thing most people want to hassle with during a vacation is a blown out trailer tire. Unfortunately, this is exactly what many could have in store for them as they pull their boat, camper, or other trailer.

In many cases it is due to overloading the trailer or under inflating the trailer tires. Heat is the culprit that ultimately causes trailer tires to fail. You can prevent heat build-up by ensuring that the trailer tires are inflated to the maximum air pressure designated on the sidewall of the trailer tire, and by not exceeding the weight limits the tire was made to withstand before hooking on and traveling at high speeds.
Other culprits
Check the sidewalls for dry rot - this looks like numerous cracks on the sidewalls (see photo). We hear from customers each day that tell us that the tread looked new, but the trailer tire still blew-out. Don't rate the quality of your trailer tires by the appearance of the tread, but instead by giving a full inspection of the sidewalls and tread. If you think your tires look suspicious, don't risk it! Trailer tire failure can result in damage to your trailer, loss of vehicle control, and can even injure you and other motorists. It is essential to check over your trailer tires before hooking on and traveling at high speeds.
