Features to know about

Built for Long Trips and Steady Highway Pulling: Load Range D with 81-mph Speed Rating

This tire-and-wheel assembly is made for real road miles. The Karrier S-Trail radial tire is Load Range D with an 8-ply rating and a maximum load of 1,220 lbs at 65 psi. It’s matched to a 12" x 4" aluminum wheel rated for 1,520 lbs, so both parts are built to handle steady highway speeds up to 81 mph (speed rating M). The setup meets DOT specifications for confidence when the miles stack up.

Corrosion Resistance that Lasts: Lightweight Aluminum AM02 Wheel

Moisture and road grime don’t stand a chance here. The gunmetal AM02 series aluminum wheel is rustproof and protected with a clear coat on both sides. That finish keeps it looking sharp while warding off scuffs, scratches, and corrosion — even after long stretches in harsh weather. Steel inserts in the lug nut wells add strength where it counts, preventing wear around the holes and keeping the wheel snug on the hub.

Smooth Performance in Wet or Dry Conditions: Radial Design with Premium Rubber Compound

The Karrier S-Trail radial tire uses double steel belts and full nylon plies to keep traction consistent mile after mile. Its computer-generated tread design and premium rubber materials deliver stable handling and dependable grip in wet or dry conditions. The result is a balanced, smooth feel on the road that holds up under real towing loads.

Ready to Trust Right Out of the Box: Tire-and-Wheel Assembly with Worry-Free Protection

This is a true tire-and-wheel assembly that’s built to go straight to work. The aluminum wheel’s 5 on 4-1/2 bolt pattern, 0 offset, and 3.19" pilot diameter make it straightforward to mount. And with Kenda’s 1-Year Worry-Free Guarantee, if the tire is damaged within the first 12 months, it’s replaced at no charge — simple protection that backs up a road-ready setup.

Determining Bolt Pattern

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.

Center to Center
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).

Center to Outside Edge
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Video Transcript for Review of Kenda Trailer Tires and Wheels - Tire with Aluminum Wheel - KE66EV

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at the Kenda Karrier ST145R12 S-Trail radial trailer tire in a load range D, and it's mounted on the 12 inch, gun metal aluminum trailer wheel, with a 5 on 4 1/2 inch bolt pattern. Now, this tire and wheel assembly is ideal for stock trailers, utility trailers, and even campers. The wheel, you can see, is a nice gun metal 5-spoke aluminum AM02 series wheel. As you notice, has a machine face and a lip, and it's durable, lightweight, rust proof.

If you notice, the front has a clear coat finish on it and the back even has a clear coat, protects the wheel from any scuffs or scratches. The nice feature I like on this wheel is the steel inserts right here in the lug nut wells. These are designed to help keep your wheel securely in place on your trailer hub. Basically, when you go to install this wheel and you put your lug nuts in there and torque 'em down, these steel inserts prevent holes from wearing down or elongating, eliminates the need for a constant retightening of your lug nuts. Now the wheel itself, the diameter is 12 inches.

The width on just the wheel is four inches wide. This wheel does have a bolt pattern of 5 on 4 1/2 inches. And if you want to measure that on a wheel that's an odd number of lugs, like in this case, five, what you'll do is pick any hole, let's say this one, and then you're gonna measure across to either one of these holes. But the trick is you measure from the center of the starting hole to the furthest edge of whichever hole you measure to. On this one, it'll measure 4 1/2 inches.

So that's telling you this is a five-lug 4 1/2 inch bolt pattern. Does use a wheel lug size of 1/2 inch by 20. And the weight capacity on just the wheel is 1,520 pounds. Now if you notice this wheel does not have a center cap. We do sell those separately, if you do want one.

You do wanna make sure to get a center cap that'll have the same diameter of the pilot hole right here, which is 3.19 inches. Now this tire that's mounted on it, it is a Kenda Karrier S-Trail radial tire, uses double steel belts, full nylon plies, which combine for superior function and long life. And if you look at the tread on this, it is a computer-generated tread design. And they use premium rubber compound materials that'll give you superior traction on wet or dry conditions. The tire is an ST tire, which means special trailer tire, so it does have the sturdy sidewall so they could handle heavy loads, and it is created specifically for trailers, not intended for use on other vehicles. The tire size which will be stamped on the sidewall, ST again for special trailer, 145R12, R means it's a radial. Section width, 5.8 inches. Overall diameter from the bottom to the top when it's inflated, it's 21.4. And this tire is a load range D, which means it's an eight-ply rated tire. So it does have a maximum load capacity of 1,220 pounds at 65 PSI. And one of the last things I wanna mention to you is they do do a speed rating now on these trailer tires, and it is stamped on the sidewall, but it is a letter designation. And the way you'll find that is right down here where the tire size is listed. Right after it, you'll see a number for the load index, and then you'll see the letter M stamped there. Speed rating M means it's an 81 mile per hour speed rating. Now this tower wheel assembly does meet the Department of Transportation specifications. But that's gonna do it for a look at the Kenda Karrier ST145R12 S-Trail radial trailer tire in a mode range D on this 12 inch gun metal aluminum trailer wheel.

That's a sweet boat you got, Samuel! Now you're ready to get on the water and enjoy the sun!

Quality look and feel. Replaced 4.80x12 bias with 145 R12’s. Glad I did and they look great on the jet ski trailer.
by:
As always the documentation of products is excellent, both written and video. Ordering is extremely simple and shipping was quick and on time. The packaging was robust but easy to handle and of course I received exactly what I expected. I did want to confirm the proper lug nut torque and I received an answer via a chat session within minutes. Etrailer has an "A" game that always executes when I shop and order.

Product is great and its a much safer feeling having the load range D tires and 81mph speed rating vs the original B range and only 65mph speed rating!

by:
Tires seem fine but the wheels are a real problem They don't leave adequate clearance to get a lug wrench on a 7/8 or 13/16 lug. You must use a thin wall socket, something you would not want to find out on the road. I would have preferred a steel wheel but it wasn't offered with this load range tire.
by:
great tires. I used them on a self-assembly utility trailer kit that had donut tires rated for 55mph.
by:
Wheels look great, appear to be good quality, and were delivered fast and packaged well! Definitely a nice upgrade to our camper.
The only thing I would recommend is that you determine if the lug nuts and wrench you are currently using will work with this wheel. The lugs that were used on my old set are a typical (shallow) lug nut. The lug hole openings on these wheels are fairly narrow and my lug wrench was too large for the opening.
I ended up using a ‘DORMAN Spline-Drive Wheel Lock Kit’ (711-255) that had a very narrow ‘key’ socket and fairly long chrome lugs. The ‘key’ socket slips over the lug and then you can use your lug wrench. Just be sure to keep everything lined up and you torque the lugs with equal and straight alignment. I’ve heard the ‘key’ could be sheared if not used properly. That said, this worked very well for my setup and the key seemed like it was good quality as well. I’ll just need to make sure the ‘key’ socket stays in the camper with the lug wrench. If not, you’re kind of stuck.
And, the wheels ended up looking great with the chrome lugs! I added a few photos that may help with the lug nut scenario.
by:
Outstanding customer service. My original order wasn’t in stock. I called Carter P recommended these wheels and tires. The package was sent out immediately and received 2 days early. The wheels look great. I drove over 400 miles on them so far and they’ve preformed great. Very pleased with this purchase. Thank you Carter and etrailer for a wonderful experience.
by:
Tires and rims are good quality as far as I can tell - but one arrived with a small gouge and a small a scratch on both sides of the rim. Box packaging was great and perfect shape so happened pre shipping. Not looking to replace because they will end up with some scratches and dings naturally in the future
by:
Quick Shipping. Product showed up in great shape. Boxed well and the box was sturdy. The sticker on the tire is aggressive, I can't get it all off.
by:
Super easy to work with etrailer and find the right tire for our tow dolly. Great communication and updates throughout.
by:
Wheels look great. Center hub covers and stainless steel cap lug nuts would look great but I painted my hubs black carefully using the carryover standard lug nuts and the wheels look fine. It’s a trailer. I do wish they had come balanced. Plenty of “experts” say it’s not necessary to balance trailer wheels. This engineer says that’s nonsense. Balanced tires wear better and the trailer suspension and other components will last longer if you balance the wheels. Just because you can’t feel the shake in the seat of your pants doesn’t mean it’s not happening. Overall, a nice wheel in The package and I would buy it again.
by:
Initially I had purchased two new tire & wheels for my kayak trailer and was so impressed that I purchased another one for the spare. Professional service and expedited shipping. Pleased with my purchases !! Thanks again.
by:
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.
by:
Tires were the perfect. Cannot say enough good things about Carter, he was such a huge help in getting the correct tire. Will definitely come back to Etrailer for my trailer needs. Thank you.
by:
Fast shipping and tires fit perfectly and look amazing! Installed on my carry on 5x8 trailer.
by:
Knowledgeable staff, fast shipping, great quality products and follow up customer service and support.What’s better than that? No risk purchase, these guys are professionals.Thanks again, my trailer looks great !!
by:
Shipping is stupid fast. I use them for all my trailer stuff.
