1. Size

Anyone considering purchasing an RV tire should consider the tire size that their vehicle requires. Recognizing the tire isn’t nearly as difficult as it appears. As you can see, the sidewall of a tire has a collection of letters and numbers that indicate the size of the tire.

It will have a tread pattern similar to LT225/75R16. The letter “LT” stands for light truck, and it is used to identify the type of LT tire. RV owners who possess a vehicle that falls into one of the categories should keep an eye out for tires with a combination that begins with the letters “LT.”

The letter “ST” will be used to indicate that the tires are for a trailer. Everything else is the same as it has always been.

Furthermore, the number “225” refers to the breadth of the tire measured from sidewall to sidewall in millimeters. This sample tire’s width is therefore 225 millimeters in width. This information will assist you in narrowing down the vast number of possibilities available to you in the RV tire marketplace.

Following the determination of the tire’s width, the “75” indicates the tire’s aspect ratio, which is the ratio of the height of the tire’s cross-section to the width of the tire. That is to say, the number 75 denotes a proportional relationship between the tire’s size and its width. The height would be around 168 millimeters in this instance.

Finally, the “R” indicates that the tire is radial, and the “16” means that the tire will fit a wheel with a 16-inch circumference. Overall, it isn’t all that difficult to understand. In addition, once you’ve determined the size you require, buying RV tires becomes much more straightforward.

2. Maximum weight and load rating

Maximum weight and load rating

Determine the amount of load capacity that your tires are capable of bearing. The RV and the belongings contained within it should be considered. Therefore, you should try to obtain a set of tires with an increased load capacity than the one you need.

For those interested in knowing what your tire’s load rating is, you can find it on the tire’s sidewall. You can tell how much weight you can carry by looking at your sidewall, which will say something like “Max load: 1150kg (2540 pounds)”. “2540 pounds” represents the maximum weight that the tire can support when fully inflated. As a result, if your RV has four tires, it should be able to support a maximum weight of 10160 pounds.

3. Type and class

Type and class of a tire

To find the best RV tires for class C or B, A, it is necessary to determine what class your RV belongs to. To reiterate, there are three types of recreational vehicles (RVs): class A, B, and class C (recreational vehicles). Also, keep in mind that some recreational vehicles (RVs) do not fall into any categories listed.

Those monstrous RVs that you’re used to seeing are class A recreational vehicles (RVs). These vehicles are equipped with all of the amenities you could desire, as well as the mileage of a Hummer. The type of vehicle we’re talking about is similar to a tour bus.

It is the most minor type of recreational vehicle currently available. They are referred to as campervans because of their van-like shape and the fact that they are equipped with amenities such as a small bathroom, utility room, and living space. The majority of full-time RVers do not use these types of RVs.

The standard camper you had in mind is a class C recreational vehicle. These are the RVs with an attached cab and an overhang over the cab, to put it another way. RVs in this category typically have similar facilities to a class A RV but are significantly less expensive.

Because of this, all of the class RVs require light truck radial tires rather than trailer tires, as previously stated in other sections of this document. To emphasize how critical this is to achieving peak performance while also maintaining safety, I’ll repeat it:

As a result, these classes do not cover RVs such as fifth-wheel trailers and travel trailers; to ensure everyone’s safety, STs or trailer tires are required. And if you own one of these recreational vehicles, you should think about whether biased tires are an acceptable alternative for you to consider.

4. Sidewall strength

As a result, read reviews, discussion forums, websites, and other resources to form an informed opinion about each tire you consider purchasing. Take care not to make a hasty decision because buying a low-quality tire might put you in a potentially dangerous situation.

5. Place

 Do you prefer back roads or motorways for your RV trip? Will it snow or rain today? Things such as this should play a significant role in deciding which RV tires to buy. Bias tires, for example, should become a more viable alternative if you frequently travel on back roads.

They won’t blow out as rapidly as a radial tire because of their thick sidewall. On the other hand, Radial tires should be your only choice for a vacation that consists primarily of highways.

Similarly, if you plan on driving during a severe winter storm, you should consider snow tires to prepare your RV adequately. If this is the case, it is always good to inquire about them with your local technician.

6. The kind of tire you have

Now, there isn’t a certain tire type designated as an RV tire because RVs come in various forms and sizes, including campervans, motorhomes, campers, and other recreational vehicles. The term “RV” has become so broad that manufacturers have categorized RVs into three categories: class A, class B, and class C. This is because the term “RV” has become so broad.

Differences between Sailun s637 and Goodyear g614

Differences between sailun s637 and Goodyear g614

Sailun S637 tires are pretty competitive with Goodyear G614, according to anecdotal accounts on this forum and others, and often at a considerably lower price. However, there is a significant distinction. Goodyear offers a Damage Policy for the G614 and a few other tires. If your RV is damaged due to a G614 failure, Goodyear will cover the costs of repairs.

In 2014, a four-year-old G614 with 40,000 kilometers on the clock blew out its tread, inflicting body damage. Goodyear covered the cost of roadside supply and installation of a substitute tire, as well as around $2,200 in RV bodywork.

Sailun or any other tire company that I’m aware of does not pay for body damage repair. It’s also odd to spend $550 for roadside repair and installation on a tire that’s four years old and has 40,000 miles on it. It’s important to note that this is a Goodyear policy, not a warranty. That means they can change their policy at any time. Regardless, Sailun produces a solid tire at a reasonable price.

As you might guess, a motorhome requires tires that prioritize traction over all else because it may need to make abrupt turns. Consequently, you must understand the types of RVs you own; otherwise, you will be unable to determine which type of tire you require.

No matter how you intend to use your RV, you’ll require a tire with a durable, tough sidewall to get the job done. As a result, you must conduct the necessary research on each tire you consider.
