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.

Bolt Pattern - Odd

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.)

Bolt Pattern - Even

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.)

Bolt Pattern - 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.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Video Transcript for Kenda Tires and Wheels AM31957 Review

Today, we're going to be reviewing part number AM31957. This is a Kenda Karrier Tire ST175/80R13. It's a radial trailer tire and is mounted on a 13-inch Deckstar White Modular 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. Other thing about this wheel, this is called a white modular wheel and when the wheel has round holes like this, that's what tells us it's a white mod design or white modular wheel. White spoke wheel that you hear a lot of is when the wheel holes will be triangular shaped.

So when the wheel has round holes, we call it a white modular design wheel. We'll do a few dimensions on this wheel. The diameter from inside to inside will be 13 inches. The width of this wheel is 4-1/2 inches wide. This wheel does have a bolt pattern of 5-bolt 4-1/2-inch pattern, and on a wheel that has a bolt pattern of an odd number of lugs.

There are couple ways you can go by measuring the bolt pattern. We'll do a couple of them. The first one would be as if you drew a circle through the center of all five lug holes, then measure the diameter of that circle. So if we measured the center to the edge of that circle, it will be 4-1/2 inches. So that will say this is a 5 lug 4-1/2-inch bolt pattern.

The other way is you could measure from the center of this bolt hole directly across to a bolt hole next to it center to center. That would be 2-5/8, and then what you would need to do, will be to go to the product page for this part number. And at the bottom of the page, there is a chart and that chart will say that when the measurement is 2-5/8 from bolt hole next to bolt hole, that would signify that is a 5 on 4-1/2-inch bolt pattern. This wheel does have a weight capacity of 1660 pounds at 65 psi. It does use a wheel bolt size of 1/2 inch by 20.

Another critical measurement would be the large hole to center of the wheel that's close over the hub on your trailer. This would be called a pilot hole diameter. So if we measure the diameter for the pilot hole, it will be 3.19 inches. Now, we'll move on to the tire. This is a Loadstar, size ST for special trailer, 175/80R13. The R will designate that it's a radial tire. This tire has a load range C, which means it is a 6-ply rated tire. It will have a maximum load carrying capacity of 1360 pounds at 50 psi. And this tire we mentioned is a radial constructed tire, which will mean the belts inside the tire when it's built will run the radius of the tire or bead seat to bead seat. And the nice thing with a radial tire is because of the way that it's constructed. The tire will have more flex, which will give a better ground contact, which that will mean it will prove traction and better stability. Another nice feature, the radial tire, when compared to a bias, is on radial, will normally run cooler. So if the trailer is not overloaded, when the tire is running cooler, that means it will help the tire last longer. So this tire wheel combo does come with a limited two-year warranty. And that should do it for part number AM31957.

Haven't put the tires on yet but they look great. Nice finish on the wheels. As always, top quality products and excellent service from etrailer. 116758


Awesome! Ive put on about 100 miles since getting these. These radials get less heated from high speeds and give a much smoother ride in the tow vehicle. Switch to radial trailer tires if youre on the highway a lot and buy them here!

I received my order only a few days after ordering. The packaging was done really well. I have not used the tires yet so I can't give an excellent rating or comment on how well the tires work. The ordering, delivery and condition of my order was perfect though. Very happy. 156465

Exactly what I needed to upgrade my 'may pop' tires and rusted wheels on my utility trailer. Was wanting a load range C trailer tire, and none of the local box stores could touch this. Great trailer tire and wheel combo, good price and delivered to my door. 185840

Mounted up easy & gets the spare just out of the way of the folding down salt shield on my Aluma 8616 snowmobile trailer. Had to move everything ahead so that the mount was making contact with the coupler but it works. 175987

Ask the Experts about this Kenda Tires and Wheels
Do you have a question about this Tires and Wheel?

  • Availability of Load Star ST175/80-13 Radial Trailer Tire on a White Painted Wheel
  • I took a look at your order history, and the last tire purchase I saw was a 185/80-13 bias-ply load range D tire purchased back in 2010. This is part # AM1ST79, and was purchased as a tire only, not a wheel/tire combo. For a 175/80-13 radial tire load range C on a white painted wheel, we offer the Karrier Loadstar # AM31951 which is an 8 spoke white trailer wheel with a 5 lug on 4-1/2 inch bolt pattern. For the same tire on a white painted modular wheel with the same wheel bolt pattern,...

  • Trailer Tire Recommendation to Replace a ST165/80D13
  • You should have no problem going with a ST175/80D-13 over a ST165/80D13. The tire will only be about 10 mm's wider and 16 mm's taller. You might double check your clearances if they are close, but most likely you would have the necessary clearance for the additional width and height. If so, the Karrier ST175/80R13 Radial Trailer Tire w/ 13" White Modular Wheel # AM31957 should work well for you as long as your bolt pattern is 5 on 4-1/2. I attached an FAQ on determining bolt patters...

  • Are The Trailer Tire And Wheel Combination Balanced
  • The trailer tire and wheel combination is received from the supplier already with the tire mounted on the wheel. The supplier does not balance the combination, but when the tire is installed to the wheel they will line the high (heavy) spot on the tire with the low (light) spot on the wheel. This does not completely balance the tire and wheel combination but it does eliminate any excessive out of balance condition. I would recommend to balance the tire and wheel combination at a local...

  • Can an ST175/80D13 Tire Mount on a 13 Inch Modular Wheel
  • Yes, you can put a ST175/80D13 tire on a modular wheel. That tire size requires a 13 inch wheel that is either 4-1/2, 5, or 5-1/2 inches wide. You can use our Americana Steel Mini Mod Trailer Wheel, # AM20253, assuming the bolt pattern of your hub is 5 on 4-1/2. I have attached a help article that explains how to find your bolt pattern. This wheel will work with radial or bias ply tires and as long as the bolt pattern is compatible, you will not have a problem.

  • Spare Tire Recommendation for a ST175/80D13 Wheel and Tire
  • Since you have bias ply tires currently on your trailer I would recommend you stick with a bias ply as a spare. The part # AM31957 would work for you as it is the same tire size and bolt pattern even though the rim is 1/2 inch thinner. Instead I would recommend the part # AM3S050 as it comes with a bias ply tire like what you have. I attached an FAQ on trailer tires for you to check out as well. For a spare tire carrier you might also be interested in the CE Smith Spare Tire Carrier...

  • What is the Speed Rating for Karrier ST175/80R13 Radial Trailer Tire w/ 13" White Modular Wheel
  • All of the trailer tires that we carry are rated for 65 miles per hour. This is regardless of construction (radial or bias). But I do recommend radial tires because they run cooler and track better than bias ply tires. Bias ply tires are better for off road applications where you would be doing most of the travel off the beaten path. I have included a link to our help article on trailer tires for you.

  • Does the Karrier ST175/80R13 Wheel and Tire Combo # AM31957 Have 10 Round Holes
  • The wheel in the Karrier ST175/80R13 Radial Tire and Wheel Combination, # AM31957, comes with the 10 round holes, not a spoke pattern. The pictures you see on our product page are actual photos of the tire and wheel that we took in our photo studio. We had this wheel in stock, so I pulled it from our warehouse and made a short video for you.
