This tire has a 1-year worry-free guarantee. If within the first 12 months the tire is damaged in any way, it will be replaced at no charge.
Determining the Bolt Pattern
The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.
To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)
On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)
Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look at this Kenda Karrier ST145/R12 Load Range D S-Trail Radial Trailer Tire with 12-inch aluminum wheel. Now, this tire and wheel assembly is gonna be ideal for your trailer. This special trailer tire or ST tire has double steel belts and full nylon plies for superior function and long life. The computer-generated tread design and premium rubber compound materials are gonna give you superior traction in wet or dry conditions. So again, this is an ST tire or a special trailer tire, and this is designed for trailers only and not vehicles.
So as I mentioned at the beginning of our time together and as we have stamped here on our tire, this is an ST145/R12. The section width is 5.8 inches, and the outer diameter when fully inflated is 21.4 inches. And this is a load range D, meaning it has an eight-ply rating. The maximum load is 1,220 pounds at 65 psi. And this has a speed rating of M, indicating the maximum speed of 81 miles per hour.
Now, this black aluminum AM01 series wheel is durable. It's lightweight, it's attractive, it's rust proof, and the the clear coat finish on the front and the back is going to protect it from scuffs and scratches. And as you can see here, this features this spoke design here with a machined face, so it's really gonna look great on your trailer. And this also features steel inserts in the lug nut wells to help keep the wheels securely in place on your trailer hub, preventing the holes from wearing down, eliminating the need for constantly retightening your lug nuts. And the dimensions of our wheel, looking at the diameter first, measuring bead seat to bead seat is 12 inches.
And the width of the wheel is four inches. And our bolt pattern is five on 4-1/2 inches. And in case you don't know, the first number in the bolt pattern is the number of bolt holes and the second number is the diameter in inches of the circle on which the bolt holes sit. So to determine the bolt circle diameter on wheels with an odd number of bolt holes as we have here, you simply measure from the center of one bolt hole to the point halfway between the two bolt holes directly across from that first, and you'll get that measurement. The capacity of this wheel is 1,520 pounds.
The wheel stud size is a half an inch by 20. The center cap is sold separately, but if you decide to pick one up, you just wanna make sure that it fits the pilot diameter of 3.19 inches. And this assembly does meet the Department of Transportation specifications. Well, I think that's gonna wrap up our look today. I do hope that our time together has been helpful for you. Again, my name is Andy. Thank you for joining me.
