Long-distance towing puts real stress on your setup, and this combo is built to handle it. The Karrier ST205/75R15 radial tire carries a 6-ply rating and 1,820-lb maximum load at 50 psi, matched to a steel wheel rated for the same capacity. With its M speed rating of 81 mph and DOT compliance, it’s ready for steady highway miles in heat or rain without breaking a sweat.
Moisture, salt, and road grime can wreck an unprotected wheel fast. This 15" x 6" conventional steel wheel uses an e-coat primer topped with a corrosion-resistant black powder coat finish that keeps rust away and looks sharp season after season. It’s a solid match for anyone who wants reliability and a clean finish that stays that way.
The radial design makes this tire run cool and track straight. With cords set at a 90-degree angle to the direction of travel, it resists heat buildup and rolling resistance better than bias designs. Double steel belts and full nylon plies give it long life, while the computer-generated tread pattern provides solid traction in wet or dry conditions.
Getting alignment right means better handling and even wear. This tire-and-wheel setup uses a +0.5 mm positive offset to position the wheel closer to the frame for proper load balance. The 5 on 4-1/2 bolt pattern and 2.62" pilot diameter make it easy to match standard hubs, while the conventional style pairs perfectly with optional baby moon wheel caps for a classic look.
No extra steps needed—this tire arrives mounted and ready to install. Every assembly meets Department of Transportation specifications, so you can bolt it up and get back on the road knowing your setup is safe, consistent, and built to perform under real towing conditions.
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"

Great service
great company to deal with.
Awesome, balanced, packed well and ready to mount. Ive gone thousands of miles with no issues
Seem to be of very good quality. Wheels are made in USA.
Was very pleased with my purchase from etrailer.com. The website was easy to use, I was able to find exactly what I needed and my order was shipped in a timely manor.
Got my spare tire and rim in, works great. And all the other little stuff worked great to, as always.
I decide to replace the tires that are thirty years old so I chose etrailer. I bought one with free shipping to make sure it fit. With all the info they give, I new it would. UPS dropped it off by my trailer. Good fit. Turned around and ordered the other three.
Super fast shipping. Excellent product. Had the wheels and tires mounted and up and running in no time.
Looks great on a 57 trailer
I bought these rims and tires to go on my 1961 Serro Scotty Sportsman camper that I am restoring. I also purchased the moon hubcaps to give it a true retro look.
A perfect replacement for the rusted rims and weather checked tires now on it. Thanks etrailer!
Look great, fast shipping at a great pr ice!
This wheel/tire combo is exactly what my vintage trailer rebuild needed!
This is less about the product and more about the warehouse that picks the order. I ordered two 15x6 with 5 on 4.5 bolt pattern, I got one with 5 on 4.5 and one with 6 on 5 with a 3.5 pilot hole. It's pretty obvious the two were not the same.
Super fast shipping, they look great on Petunia, our 1959 canned ham Shasta, all came in two days, FREE, air in the tires, no worries and the half moon hubcaps look great. I am sure the tires will be fine as well. Great shopping experience.
No problems to report so far. These arrived in good condition in less than 3 days. The tires are slightly wider (sidewall, below tread) than some others I've tried & the center hole on the wheel is slightly smaller. Clearance on my old Hadco Engineering # 3114 hubs was tight, but the wheels went all the way on. A test drive on a variety of roads, up to highway speeds, was uneventful.
I bought these wheels along with the baby moon hubcaps. First off, they look amazing on my trailer. Secondly, they perform very well. My trailer rides so much smoother now that I have radial tires on it. I'm surprised that I can tell the difference, but I really can. I'm super happy with this purchase!
Shipping was fast. Price is very reasonable. My baby moons fit perfectly. All this enhanced the old Shasta camper I am restoring. These tires will likely last the lifetime of this camper. I am excited to get it on the road. Only issue, which is minor, is that a white sticker was slapped on the tire and was very difficult to remove. If it had been placed on the inside wall of the tire I would not have minded it so much. Other than that I am very pleased. Thanks.
