When you’re pulling serious weight over long distances, this tire-and-wheel combo is built to take it. The Westlake ST225/75R15 radial tire carries a Load Range E rating with a 10-ply construction and a maximum load of 2,830 lbs at 80 psi. Its L-speed rating means it’s good for 75 mph, giving you confidence on the highway whether you’re hauling cross-country or heading out for the weekend.
Rust doesn’t get a foothold here. The 15" x 6" modular steel wheel starts with an e-coat primer and finishes with a silver powder coat to resist corrosion from rain, road salt, and moisture. It meets SAE J1204 standards and is rated for 2,850 lbs—strong enough for tough jobs in any climate.
The Westlake radial design uses double steel belts, double polyester plies, and nylon tread overlays that help prevent separation and heat buildup. That means smoother tracking at highway speeds, less rolling resistance, and longer tread life than bias tires. It’s engineered to stay cool under load so you can tow with confidence mile after mile.
Skip the tire shop stop. This setup comes pre-mounted and ready to install so you can bolt it on and go. It’s already aired up to proper pressure and balanced by matching the heavy spot on the wheel to the light spot on the tire for stable towing right away.
You get backing that goes beyond basic coverage—a 1-year No Excuses Guarantee that replaces the tire if it’s damaged in the first year, plus a 5-year tire warranty, a 1-year wheel warranty, and complimentary roadside assistance for 2 years available 24/7 in the U.S., Canada, or Puerto Rico.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Ratings & Reviews
Great quality, timely shipping/delivery. Only thing that would make this purchase better, the tire/rim packages being balanced. I had to go to discount tire and have them balanced. I know that sounds petty but you wanted an honest opinion.
Excellent purchase my spare wheel and tire showed up in two days as always it is great dealing with etrailer with excellent service and fast shipping thanks
everything is as ordered and look great only problem is tires are going on an old trailer and now I will have to paint it to match the new tires and rims such is life
Tires & wheels look & fit great . Best of all was the great service . I was not pushed for time on receiving my order, but they arrived in 2 days. GREAT SERVICE. If only my post office could be that good.
Ashley in customer service is Awesome she done everything for me that I asked about. Great job and Thank you. As far as the tire and wheel they look very nice, I don't have them installed yet but I'm sure they will be awesome. Good people seem to work there. The tracking was different than I have ever experienced from UPS but the tires made it here so I'm not complaining. Great job to every one involved.Thank you and I will use you all again.
Easy website to order from, placed my order for a new tire and wheel and it arrived 2 days later in a box with carrying handles! Installed it and took out the camper that same day. Great product and service!
I recently purchased a spare tire and tire carrier from etrailer. I had the bracket and the tire mounted in 5 minutes. I am very impressed. I will definitely order from etrailer again.
Tire/wheel arrived on time in a nice sturdy box. Much better than the loose tires I have received from other retailers.
This wheel tire combo appears to be an exact match for the ones that came on my Hawke dump trailer, right down the green valve stem caps.
This should allow me to rotate this one in with the tires already on the trailer.
Tire came in a box just for tire size. Heavy duty box with holes for shippers to easily handle and not just tgrow around. This was tire and wheel so not light.
Packaging was great.
Tire was direct replacement for other spare on my 5th Wheel. I plan to travel with two spares.
Bought 3 of these tires for our boat trailer. Trailer is kept in the garage. Less than a year later while coming back from the lake the tire came apart on the road. We were lucky no one was seriously hurt or any major damage to our boat. Totally destroyed the fender on the trailer. When I contacted the company about the warranty at first I was told they would ship me a new one and they would cover shipping the bad one back. I got a phone call later that evening telling me I would have to pay for shipping it back and they might consider replacing it. Learned our lesson, won’t buy from this company again.
I recently purchased a bucket lift and had to pick it up on the other side of the state. I was looking for a spare tire as a precautionary measure. Several merchants claimed to have the tire and rim and when I tried to purchase them, found that they didn't have 6 hole rims. If I would have placed the order from e-trailer when I knew that I was purchasing the lift, I would have had a great spare tire and rim instead of sweating a 200+ mile ride with no spare.
Very good product! Top of the line for a very reasonable price. The best service from Roger, when I received an email that my original choice was on back order, Roger offered a better product that was in stock. He shipped it out the same day. Will order from him again.

Still have not used it. Spare
It was bought for a spare. Haven't had to use it and it is still holding air, so 5 star rating. etrailer has always been a really good company to deal with. have bought several different trailer tires through them and have always been satisfied.
The boat trailer that I recently purchased came with one bad tire and no spare so before I hit the road for some summer fun I bought two of these tires and rims so I would have an extra for a spare. I mounted the tires and hit the road. They are heavy duty and have a great ride, would recommend to family and friends, great product.
I installed Westlake tires on my 21ft toy hauler last spring and they have been great! I had Power King tires on it before and it seemed like I had a blow out every other trip. ~2,000 miles on them so far and look forward to another worry free season. Shipping was fast with no issues.
Used as a replacement on my dumpbox trailer. Matched the other tires on the trailer. Resilient against nails and easy to repair when one does make it through. Warranty through this company is also great, they replaced the blowout for free and paid for the mounting services, kept it as a spare.
Customer service is the best! We had questions and they were answered with someone knowing what they were doing. I recommend Etrailer we will be purchasing from them again soon!

Its been a year since we purchased the tires. They are doing great! It seems like they will last longer than the original ones. Thanks!!
Great tire exactly what I was looking for at a great price was actually shipped and delivered same day as projected unlike other websites that take up to 2-3 weeks all around pleased with the experience
Not impressed. Always inflated and never overloaded but started separating while it was on the spare holder.

I would have you reach out to the manufacturer about this. The tire has a five year warranty so time wise, you are still within that timeline. I have already sent you an email with their contact information.
Product was exactly what was shown. It matched what i have on my trailer and was what i wanted as i travel twice a year to bring my daughter to college. I wanted the same tire and rim so all tires wear and travel the same as it is 1000 miles each way. The tires get a lot of long distance use.

The trailer is coming out of storage from the winter. I have 4000 miles on them so far so good.Getting ready soon to travel again to get my daughter. Hopefully the trip will be uneventful and all will be good in the world when i travel. Great tires and rims will definitely buy more when i need them.
Tire and Wheel look good on the new hub conversion. Went from a old 4 bolt Dayton hub to a new 6 bolt hub. Conversion was super easy! Takes a lot of stress off me going down the road!
Wheels and tires arrived in great shape, they seem like well constructed units, but I suppose time will tell, right now they are 5 star...
Excellent wheels, they serve as a good replacements for 70’s model Airstreams wheels.
My only complaint is that I received 3/4 of my order, and I’m responding to the email that states my order was delivered. short a wheel. Please help
Tires and rims are great. Price is right on and delivery on target.
Yea..... It's just a dump trailer... but there is no greater relief than to have a great tire that will not be smoking on the highway when it goes flat from Roofing nails!

From the looks of the tire, the tread delaminated from the tire, which happens when the tire is low on air pressure combined with highway driving heating the temperature on the inside of the tire. You will want to make sure the tire has a PSI of 80 before heading out.
