When you’re running long hauls or carrying a full load, this setup is made to hold steady. The Karrier S-Trail radial tire has a ply rating of 10 and carries up to 1,520 lbs at 80 psi, paired with a durable aluminum wheel rated for the same 1,520 lbs. It’s speed rated M for 81 mph and meets DOT specs, so it’s ready for highway use without worry about heat or load stress.
Corrosion doesn’t get a foothold here. The 12" diameter x 4" wide aluminum AM02 wheel is lightweight, strong, and fully rustproof. Its split-spoke design features a machined face and a clear-coat finish on both sides that stands up to scuffs, scratches, and road grime. Even in wet or humid conditions, it keeps its clean, sharp look season after season.
The Karrier S-Trail radial uses double steel belts and full nylon plies for stability and long tread life. A computer-generated tread design with premium rubber compound provides solid traction in wet or dry conditions and helps the tire run cooler on extended trips. That combination gives the steady tracking and sure grip you’d expect from a well-built radial tire.
Peace of mind is built in. If this tire is damaged in any way within the first 12 months, it’s replaced at no charge under the 1-year worry-free guarantee. The wheel itself carries a 2-year limited warranty, so the whole assembly is backed for real-world use mile after mile.
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"

Exactly what I needed. Shipped super fast. Great follow up from Etrailer.
Nice price, fast shipping easy checkout they look awesome, glad I ordered from you.
They certainly look great. Hope road performance is as good
I was blown away by this tire & wheel combo, An amazing price for an alloy wheel with a quality, load range E, 81 mph tire. And the tire is made in Taiwan, NOT China! The shipping box was heavy duty and perfect for shipping a pair of wheels. The entire customer service experience could not have been better. From acknowledging receipt of the order to keeping me updated, the folks at etrailer were fantastic. I had considered another online retailer whose price was $15 cheaper per wheel (for a galv wheel and cheaper tire). But they wanted to charge $60.00 shipping. The bottom line is that I spent $30 less overall for much higher quality wheels and tires. Thank you etrailer!
Looks great in the box, havent put them on yet.
Need to order another for a spare, it was to ugly.
Wheels and tires were well priced, packaged and shipped to me super fast. I’m very pleased. Would highly recommend.
Exactly as described, fast shipping, great communication very nice to deal with...
Look great. Easy install. Couldn't be happier. Thank you Brandon. Good price point.
Fit our popup camper perfect
Fantastic upgrade from what I had. Definitely happy with purchase. Put them on my jetski trailer.
Spare tire. Looks like it will work.
Awesome quality wheels, 1k miles so far and they ran great, like new! I wish they didn't use such good glue on the sticker, or put the sticker on the tread instead of the sidewall, small gripe, but it is unsightly as I haven't put the effort into cleaning them yet.
Wheels & Tires arrived very quickly. Packaged in heavy cardboard box everything looks good. Mounted them on the boat trailer. Just waiting for nice weather to use them. I’ve bought from ETrailer in the passed and they’ve always been great on prices and delivery.
No problems at all. It did come in a day later than promised, but I'm not sure how they were going to get it to me that fast anyway. Still super fast delivery without issues.
They look great out of the box. Now all I need is snow to head north with the trailer.
Replaced 2 year old tires. Perfect fit and made the trailer ride so much smoother. It was a VERY noticeable improvement and now I can travel at highway speed. Great look too!
Great looking rims and tires, arrived quickly and all ready to mount.
Delivery was fast and free! The tires and wheels look great
Great product ar a fair price and lightening fast free shipping. Ordered on a Wednesday morning, tires and wheels here Thursday afternoon.
Right out of the box, mark me impressed. These really made my Sea-Doo trailer look finished. They are not much more than the steel spoke wheels with the same tires.
Quality look and feel. Replaced 4.80x12 bias with 145 R12’s. Glad I did and they look great on the jet ski trailer.
Super easy to work with etrailer and find the right tire for our tow dolly. Great communication and updates throughout.
Perfect fit! Look great! Made my boat trailer look and ride so much better. Highly recommended for the price!

That's a sweet boat you got, Samuel! Now you're ready to get on the water and enjoy the sun!
Wheels look great on my trailer. I placed the order over the phone. The lady was super helpful sending me links to the pictures and choosing the right tire size and model. I think this is a great upgrade to my trailer.

Those look fantastic, Alex! I installed aluminum wheels on my PWC trailer several years back, and it makes a huge difference!!
