Specs:
Note: The overall capacity of this tire-and-wheel assembly is limited to the lowest rated component. Do not fill your tire to a pressure greater than that indicated on the tire itself or on the wheel that it is mounted to.
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.

Today, we're going to review part number AM31233. This is a Kenda Loadstar Tire, size ST175/80D13. This is a bias trailer tire and it is mounted on a 13-inch Deckstar White Spoke Wheel. This wheel has a white powder coat finish for superior corrosion resistance on the front of the wheel and all on the back of the wheel. A few measurements we'll do on this wheel is the diameter which will be measured from inside to inside. That would be 13 inches.
The width of this wheel is 4-1/2 inches wide. The bolt pattern on this wheel will be 5 lugs 4-1/2-inch bolt pattern. And the way to measure a bolt pattern when it has an odd number of lugs, like in this case, five, there is a couple of ways. We'll show you both of them. First way is if you draw a circle through the center of all five lug holes and then measure the diameter of that circle.
So in this case, if we measure from the center of this lug hole to the edge of that circle we had drawn would have been 4-1/2 inches. So that would say it's a 5 on 4-1/2-inch bolt pattern. The other way is if you would measure from one center of one lug hole to the center of the lug hole right next to it. So in this case, it should be 2-5/8 inches and then you'd go to the product page for this part number, and at the bottom of the page, we'll have a chart and that chart will list that if that measurement is 2-5/8 inches that will give you a bolt pattern of 5 on 4-1/2. This wheel does have a weight capacity of 1660 pounds at 65 psi.
The wheel does use a bolt size of 1/2-inch by 20. Another critical measurement will be this large hole in the center of the wheel that goes over the hub on your trailer. This is called the pilot hole diameter. If we measure that, it will be 3.19 inches. And now, we'll move on to the tire.
This is a Loadstar. Again, the size is ST for special trailer, 175/80D13. The D does signify that is a bias trailer tire. This tire has a load range D tire, which means it is 8-ply rated. It does have a maximum load carrying capacity of 1610 pounds at 65 psi and this tire is of bias construction and, basically, that will mean when this was built, the belts in the tire will run the length of the tire as opposed to a radial where the belts will run the radius of the tire bead seat to bead seat. The difference is the side wall on a bias tire will give you a little bit firmer ride when compared to a radial tire. This tire and wheel combo does come with a limited two-year warranty. And that should do it for part AM31233.

I have had 2 sets of Loadstars on different boat trailers through the years and they gave me great service. etrailer offered the Loadstars on American made rims with superior load ratings at a great price. I was satisfied to wait the 5-7 days for this product to take advantage of their free shipping, but delighted when it delivered 3 DAYS from order. Tires and rims arrived in premium shape with no issues. I will not hesitate to use "etrailer.com" for my future trailer needs. A+60576

I just received my wheel and it was everything that I expected. I plan on using it as a spare wheel for my boat and carry on trailer. The wheel mounted easily to my trailer (with additional hardware). Hopefully I will never need to use it but I am glad I have it. 54263

Bought these to replace the worn tires on boat trailer. Look to be well made with a good tread. Won't be pulling the boat trailer for a month or so....so I can't review actual perfomance. I feel confident that we won't have any problems and we are extremely happy with etrailer!!33647

the wheel tire combos can be purchased elsewhere for a little more money, but there is no price that can be placed on the service or communication by the people at etrailer. this order was placed 3 calendar days ago and arrived via UPS this afternoon. 4 emails were received during this time confirming the order, tracking number, current status, and followup. In this day and age when customer service seems to be disappearing, the folks at etrailer are top notch with the way they conduct business. I'll be back -24229

Ordered 2 replacement wheels and tires for my popup camper. Shipped for free to doorstep with up to the minute online tracking available. Could not beat the price locally by just having the tires replaced nor could the local tire shop get replacement tires faster than mine arrived. Great experiance!!19839

Quality, tires were spin balanced with very little weight needed, a sign of a uniform casing. Load range D with 8 ply rated construction a excellent value for the money. Here is the positive kicker, purchased and shipped to my door for less than I would pay locally, You can't beat this deal with a stick.17303
