An Overview On RV Tires

There is nothing quite like the RV life. Getting away and exploring a new place is as easy as driving there, because just about everything you need is already in your vehicle. From taking the kids on a cross-country road trip during the summer holidays to going camping in a national park over a long weekend, RVs making traveling, exploring and wandering more fun.

Maintaining an RV properly is critical to ensuring the safety of your family and everyone else on the road. One of the most important elements to maintain are the RV’s tires. However, getting RV tires is not quite the same as getting car tires, as there are a lot of additional things you need to consider.

When looking for RV tires, the first element to research is the type of tires you will need. Special trailer (ST) tires are designed specifically for RVs. This means they can fully handle the additional weight of the vehicle because they have a stronger sidewall than regular car or truck tires. Light truck (LT) tires are made for class A, B and C rigs. If you have a larger or heavy-duty RV, it’s is likely that these kinds of tires won’t hold up to the job.

Another option is radial tires, which have steel belts at 90-degree angles. This makes the sidewalls of the tires significantly more durable and provides more efficient fuel economy. These kinds of tires are best for those who like to take long road trips or use their RV on a more frequent basis. While they can be costly, these tires have a long life.

Bias tires have nylon belts that run at 30- or 45-degree angles. This means that the sidewalls are strong and can handle heavy weight loads, more so than radial tires. However, they are less flexible, which also reduces their lifespan. These tires are ideal for very heavy RVs. Just keep in mind that they will need to be replaced every 12,000 miles.

Regardless of what kind of tire you get, be sure to consider the weight rating. The weight rating of the tires needs to be able to accommodate the weight of the RV and all of the cargo inside it. If not, the tires will wear out more quickly and will need to be replaced. Another risk of not getting the right weight rating is that the tires can blow out, which is especially dangerous while on the road.

The RV Tire Buying Guide

  • Not quite sure when you need to buy new tires? Aside from the obvious sign of having a flat or damaged tire, look for cracking along the sidewalls of the tire. This is a major sign that it is time for new tires. Keep in mind that if one of the tires is cracking, and the rest of the tires are the same age, it’s likely they will begin cracking soon, too.
  • If you bought a used RV, keep in mind that the tires may not be the same age as the RV. To find out the age of the tires, look for a four-digit DOT number on the tire’s sidewall. The last two digits are the year that tire was made, and the first two digits are the week of that year. For example, 2519 means that the tires were made in the 25th week of 2019. Most RV tires will need to be replaced every five years or so.
  • Be sure to check the tread wear in your tires every two to three months, or more frequently if you travel often. A good test is to use a penny and fit it into the tread. If the penny can stand up in the tread, then your tires are still good. If not, it means the tread is too worn out and you should change your tires.
  • When it comes to tire traction, it all depends on where you plan on traveling. For example, are you going to be driving on the highway or on back roads? Will you need to drive on long, straight roads or thin, curvy roads? Will you be facing inclement weather such as snow and ice? Understanding the answers to these questions will help you determine the type of tread you need for your RV tires.
  • If you have extra RV tires, it’s important to store them properly. RV tires should be kept in a dry and cool place indoors. Ensure they are not in direct sunlight or in air currents. Affordable tire covers are a great way to protect your tires while in storage and keep them safe them from bad weather, heat and cold.
