Westlake Radials

This radial ply tire from Westlake is constructed with double steel belts and double polyester cords for increased durability. A protective later of nylon is wrapped around the steel belts to help prevent tread separation.

Unlike standard trailer tire tread, this deep, rugged tread channels water away so that the tire makes better contact with the road. This greatly improves traction during wet, snowy, or icy conditions. Because of this, the tire is specifically designed for off-roading on uneven terrain such as mud, sand, and grass, although it performs well on highways and other paved roads as well.

Radial Tires vs. Bias Tires

Radial tire vs bias tire graphic

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.

Excellent service and tracking ability for delivery

Great off-road trailer tire at a great price!


Excellent tires and service. They have been durable and reliable over the year we've had them.


The electronic order was smooth and the delivery was expedient and I would do business with E Trailer again.


I ordered my trailer tires online on a Sunday. Eight days later the tires arrived via UPS exactly what I ordered. I'm very happy with the service!

  • How To Determine If Load Rating of Westlake ST235/75R15 WST54FR Is High Enough For Trailer
    Yes. To figure out if a tire is able to support the weight of your trailer you need to take the max load rating of the tire and multiple it by the number of tires on your trailer. Since your Geo Pro G16BH has a GVWR of 3961lbs and has two tires, and the Westlake ST235/75R15 Radial Off-Road Trailer Tire - Load Range D # WST54FR has a load rating of 2,910-lb at 65 PSI they will be more than capable as the combined weight capacity will be 5820lbs. Another option that will fit your trailer...

  • What is the Weight Capacity of the Westlake ST235/75R15

  • Is There a Minimum Clearance From Trailer Frame or Wall Needed on Trailer Tires
    There is not a minimum or maximum width but you're generally going to want at least 1". Because the tires don't turn, you're not really restricted and may be able to get away with slightly less, but generally 1" is going to allow for sufficient tire flexion. With that said, in comparing an ST205/75D15 like the # AM10245 to an ST235/75R15 like the # WST54FR, there is a 1.2" width difference and also a 1.8" height difference; you're not only adding a wider tire, but also one that is taller...

  • Recommended R-Pod Tire Replacement for ST235/75r15 Tires with Load Range C
    I have a solution for you, but we won't have a tire that is ST235/75r15 that isn't an off-road type tire like the # WST54FR. With that said, you could go down to an ST225/75r15 tire like the # LHWL304 and only lose about .2" of total ground clearance. These tires have a Load Range E with a maximum capacity of 2,830 lbs at 80 psi and a speed rating of L- which means they're safe up to 75mph. This would be the best solution available and would be a good alternative to your current off-road...

  • Recommended Upgrade to 235/75r15 Load Range C Tires on 2021 Geo Pro
    The only ST235/75r15 tire we have available is the Westlake ST235/75R15 Radial Off-Road Trailer Tire - Load Range D # WST54FR which has a load range D and capacity of 2,910-lbs. These are a really nice, aggressive looking tire that we see used a lot on off-road style trailers like the Geo Pro, and they're going to give you a little bit beefier tire compared to your load range C tires. With that said, there is not a load range E tire available in this size, but you could go down to the...

  • Replacement Wheel And Tire Options For 15" Trailer Tires
    In order to determine if 235/70R15 tires would fit your trailer, you will need to take a few measurements for clearance. A 235/70R15 tire typically measures 28" tall and 9.3" wide. The closest tire size we have is 235/75R15 Westlake # WST54FR, which measures about 28.9" tall and 9.3" wide. You can find the wheel/tire combo here: Westlake ST235/75R15 Off-Road Trailer Tire w 15" White Spoke Wheel - 6 on 5-1/2 # WST94FR. The wheel lug pattern is 6 on 5-1/2".

  • Can The Westlake WST54FR Be Run At A Lower PSI
    Running the Westlake ST235/75R15 Radial Off-Road Trailer Tire - Load Range D # WST54FR at a lower psi than it is rated to can soften the ride a little. However, doing so can and will also cause the tire to wear unevenly, so it is not recommended. Comparing these to your current tires will depend on said tires. The # WST54FR will be a Load Range E, or 2,910 pounds at 65 psi, so they are pretty heavy duty. Radial tires are designed for more comfortable highway use than a bias ply tire,...

  • Checking For Larger 15" Tires When Lifting a Torsion Axle With 205/75-15 Tires
    Currently our tallest 15" tires are going to be the Westlake ST235/75R15 Radial Off-Road Trailer Tire # WST54FR. These tires are 1.8" taller and 1.2" wider than your current 205/75-15" tires. With you adding a lift like the Torflex Lift Kit # K71-707-01 you should have plenty of vertical clearance but you should still still check the fender clearance as well as side wall clearance since the tires will be wider. The sidewalls I like to have at least 1" of clearance and 3" of vertical...

  • Recommended ST205/75/15 Tires For 2021 Lance 1685 Travel Trailer Being Towed On Rough Gravel Roads
    We have exactly what you are looking for. For your 2021 Lance 1685 Travel Trailer that you will be driving on rough terrain I recommend replacing your ST205/75R15 Goodyear Endurance Tires with the Taskmaster ST205/75D15 Bias Trailer Tire - Load Range C # TTWSF20515C. These tires are bias play which is better for off-road use due to the the direction of the plys that makes it more flexible and increases traction on rough terrain.

  • Can ST235/75R15 Tire be Used on Same Rim as ST205/75R15
    It depends on the tire; for example the Westlake ST235/75R15 Radial Off-Road Trailer Tire # WST54FR fits a 15" x 6" rim. So if that's the size of rim you currently have, you can use this tire. Otherwise, you may want to go with a ST225/75R15 tire like the Karrier ST225/75R15 Radial Trailer Tire # AM10256. This tire can fit 15" x 6", 15" x 6-1/2", and 15" x 7" rims so there are more rim size options that may align with what you have. Also keep in mind these add more than an inch in diameter...

  • Westlake 235/75-15 Tire on 5 on 4-1/2 Inch Bolt Pattern
    I'm unable to find a Westlake CR875, even on their website so I'm unable to determine what exact wheel that is. Since we only offer that ST235/75-15 tire mounted on a 6-on 5-1/2 inch wheel, you'd need to purchase the wheels and tires separately and have them mounted locally as we don't have the equipment to do so here. We sell the tire individually as part # WST54FR. and we offer the following 15 x 6 wheels with a 5-on 4-1/2 inch wheel bolt pattern: -# LHSO320B -# LH44FR -# 274-000031 -#...

    The Dexstar Conventional Steel Wheel with Offset - 15" x 6" Rim - 5 on 4-1/2 - Black # AM20504 which is slightly wider than the Dexstar Conventional Steel Wheel with Offset - 15" x 5" Rim - 5 on 4-1/2 - Black # AM20404 is the widest wheel we carry in that diameter with the Conventional wheel design and offset.

  • Recommendation For a Larger Tire After Doing an Axle Flip
    Flipping an axle can cause there to be a pretty large gap between the wheel and fender, so you can definitely go larger with your tires. That being said, the 5 bolt patterns will only go up to a 15 inch wheel. The Kenda Karrier ST225/75R15 Radial Tire with 15" White Spoke Wheel # AM32545 will have a diameter of 28.4 inches. This will also use a 5 on 4 1/2 bolt pattern. This looks like the bolt pattern you have, but it should be verified before getting too far ahead of ourselves. When...

  • Can Trailer With Existing 205/75-15 Tires Increase Tire Size to 235/75-15
    It'll depend on how much fender/frame clearance you currently have. Going with a larger tire such as the ST235/75-15 # WST54FR tire would increase the tire diameter by about 2 inches and the width by about an inch. This will move the top of the tire about 1 inch closer to the inside top of the fender or wheel well and about 1/2 inch closer to the trailer frame to the inside. With the trailer loaded up as you'd typically have it, you want to see 4 inches of clearance above the tire...

  • Can 5 Year Old Trailer Tires that Were Covered and Look Good be Used
    With trailer tires they say that they need to be replaced between 4 and 6 years of age due to them breaking down over time. Since yours were covered mostly and there are no visible signs of failure I would easily think you'd be able to get the max year range of 6 from what you have. I'd just keep an eye on them. In your tire size of 235/80R16 we have the great # WST54FR for if you were to need a replacement.
