Who Should Buy Trailer Tires

  • Trailer owners. Quality trailer tires are essential for those who tow and haul in any capacity. It doesn’t matter whether you own a boat, RV, or flatbed trailer – a good set of trailer tires are a must.

Who Should Not Buy Trailer Tires

  • Other vehicle owners. As there are key differences between regular tires and trailer tires, it’s downright dangerous to use a trailer tire on your car. These specialty tires should only be used with trailers and not on cars or other vehicles.

Research Tips (from an Expert)

Tires, be they for trailers or cars, are not a one-size-fits-all type of purchase. Each trailer has specific requirements based on total weight, weight distribution, speed it can be safely towed, and so on. You’ll need to keep all these factors and more in mind as you shop for the correct trailer tires for your application. As you begin your research, you’ll want to consider all the following:

  1. Check the tire type. You can quickly work out the type of tire by the first letter in the identifying code: P means passenger car, LT means light truck, and ST indicates special trailer. Trailer tires will start with ST, such as ST 225/75R15.
  2. Verify the tire width. Next, you’ll need to ensure the correct width. The number listed after the tire type indicated is the width of the tire in millimeters. If the code is ST 225/75R15, the width of the tire is 225 mm.
  3. Verify the tire height. When dissecting the tire sizing code, check the middle number between the slashes, which represents tire sidewall height as a fraction of the width. In our example, ST225/75R15, the height of the tire is 75% of its width of 225 mm.
  4. Verify the wheel diameter. The last number in the sequence is the diameter of the wheel in inches. In our example, ST225/75R15, the wheel is 15 inches in diameter.
  5. Consider the construction. Radial tires have rubber-coated steel cables running perpendicular across the tire and are better for long distance travel; they also feature lower rolling resistance, improved cooling, and a longer tread life compared to bias-ply tires. Alternatively, diagonal bias tires use layers of nylon textile cords crisscrossing at 30° angles, and are better for shorter distances or off-pavement situations. Diagonal bias tires have a shorter tread life than radial tires, and are indicated by the letter D in the tire code.
  6. Check the load rating. All trailer tires will have a maximum recommended load. Be sure to follow the manufacturer’s recommendations to ensure the gross weight capacity of the trailer is evenly distributed across tires that can handle such weight.
  7. Check the speed rating. If you plan on running your trailer tires down the highway, you’ll want to choose a tire with a higher speed rating. Newer trailer tires indicate their speed rating with a letter on the sidewall, with M for 81 mph, L for 75 mph, and J for 62 mph. Note that most trailer tires typically encourage drivers to cap their cruise control at around 65 mph to mitigate any chance of premature tire failure.

How Much Do They Cost?

Between $50 and $100

For most trailer tires, you can expect to pay between $50-$100 and still get a quality product. A major component of price is tire construction – whether or not the tire is constructed radially or diagonal bias can have a significant effect on price, as will the load and speed rating. The size of a trailer tire is also something to keep in mind when analyzing prices. Oh, and was a rim included? If so, you’re certain to pay more than a comparable tire sans rim. The best and priciest trailer tires will cost you upwards of $200.

Frequently Asked Questions

Are bias ply tires better for trailers?

Diagonal bias, or bias-ply tires, use layers of nylon textile cords crisscrossing at 30° angles. They are better for trailers navigating short distances or off-pavement situations. Diagonal bias tires have a shorter tread life than radial tires and are indicated by the letter D in the tire code. It is not recommended to mix and match trailer tires types.

How long do trailer tires last?

Trailer tires should last about five or six years before requiring replacement. But keep in mind that, if you’re like most trailer owners, you’ll be lucky to see 30,000 miles on a trailer tire before needing replacements. This is largely due to the age part of the equation, not the tread wear.

How do you know what size trailer tires to buy?

You can work out what size trailer tires to buy by looking at the sidewall of the tire that you are replacing. As discussed above, the identifying code will detail what you need to know in order to purchase the right size tire. You can also check the manufacturer’s recommendations for your particular trailer.

Do trailer tires have to be balanced?

Unlike passenger tires, trailer tires do not need to be balanced, as they are not gripping through turns in the same way as a vehicle’s tires need to. When it comes to trailer tires, steering and cornering are less of a concern. That said, there are still significant benefits to balancing your trailer tires. We recommend taking a look at the article linked at the beginning of this paragraph to better understand the pros and cons of balancing your trailer tires.
