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 Dexstar Tires and Wheels AM20504 Review

Today we're going to review part number AM-20504, this is the Dexstar 15 inch by 6 inch conventional steel trailer wheel, with the positive .5 inch offset and the 5 on 4.5 inch bolt pattern. This wheel is a sturdy steel construction, has a nice black powder coat finish over Eco Primer over the whole wheel. This is for excellent corrosion resistance. This wheel is a conventional design wheel; it does not have any spokes or holes to it. This design is basically what was used on a lot of the automobiles that would accept hubcaps; it's designed to accept a hubcap. It has a positive offset, which insures in the wheel's position closer to the trailer frame. This is a high quality wheel that meets the Department of Transportation specifications.

Now a few specs on this is the dimensions is a 15 inch diameter, by 6 inches wide. If you go to measure the wheel, what you'll be measuring is actually the inner to inner, which is the bead seat to bead seat. Basically when a tire is mounted on to this wheel, the beads of the tire would seat right here, so you're going to measure inside to inside. When you do measure it you can see it coming up to a 15 inch diameter, and on the width we'll do the same thing. Measure inside to inside which is the bead seat to bead seat. Put a ruler on that, we can see it's right at 6 inches wide, so this wheel would be 15 inch diameter, 6 inches wide.

It's supposed to have a bolt pattern of 5 lug 4.5 inch bolt pattern, and if you're going to measure the bolt pattern, especially on a wheel that has an odd number of lugs, what you want to do is pick 1 of the lug holes, then start with that hole, and just measure from the center of that hole to the furthest edge on the whole right across from it. You can go to either this hole, or this hole; either one of those holes will get you the correct measurement. What we're going to do is I'm going to start with this hole and go over to the furthest edge on that one. The starting hole you'd go to center, and over here to the outer edge is 4.5 inches, so 5 lug 4.5 inch bolt pattern. It does have a wheel lug size of .5 inch by 20. The pilot hub diameter which is the hole here at the center of the wheel goes over the hub on your trailer.

The diameter of that is going to be right at 2.62 inches for the pilot hub diameter. Now this wheel does have a weight capacity of 1,820 pounds, and the last thing, very important, is that this wheel has the .5 inch positive offset. Basically what that's saying is an offset on a wheel is when this center plate is - right at the centerline of the wheel that's the zero offset - so if this mounting surface plate back here that goes on to your hub or drum on your trailer - if that position of that plate would move towards the outside of the wheel or trailer, that would be positive offset. If it went deeper, then it would be a negative offset. This has a .5 inch positive so this mounting surface, if you measured it, would be .5 inch from the centerline of this wheel, positive to the outside of the wheel. What that does is this will allow the entire wheel to move closer to the trailer frame. Sometimes on some applications the reason they put offset on some wheels is to give extra clearance in here.

If there's something on the axle that needs to clear. That should do it for the review on part number AM-20504, a Dexstar 15 inch by 6 inch conventional steel trailer wheel, with the .5 inch positive offset and the 5 on 4.5 inch bolt pattern. .

I just received my latest order from e trailer. I have ordered quite a few things from them. At first I was skeptical but I am an etrailer fan now. The website works well. Lots of good resource information on products. Shipping is prompt and I always get a follow up email. I order on line quite a bit and these folks have it figured out. 163410

Wheels look really nice but after installing them on my trailer I noticed that the wheels are not as true as I would like. You can see a wobble in both wheels due to poor alignment when made. I'm sure it will be fine but they are not as true as the wheels on my other trailers. 193298

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

  • Will Americana Baby Moon Trailer Wheel Center Cap Part # AM90086 Fit 15-Inch Rims on VW Trike
  • The Americana Baby Moon Trailer Wheel Center Cap, part # AM90086, is intended for 13-, 14- and 15-inch conventional 5-lug trailer wheels. Since your VW Trike wheels are 15 inches and have roughly a 9-1/2 inch snap ring around the hub, these 9-1/2-inch center caps may work. I have provided a link to one of the 15-inch wheels we offer that this center cap fits. I have also included a photo of the wheel with measurements that I took from a sample in our warehouse. You can compare these...

  • Spare Tire and Wheel Recommendations for a Nitro Dual Axle Boat Trailer
  • The 14 inch tire on your boat trailer is most likely a 5 on 4-1/2 bolt pattern. You will need a 14 inch wheel to match the other wheels on your trailer. I have included a link to an FAQ that shows how to measure for bolt pattern. The wheel that you referenced, # AM20504, is a 15 inch wheel and it has an offset which is not all that common. If you just want a wheel, # AM20352, is the most common. In the event that your wheels do have an offset, you would use # AM20304. For a standard...

  • Max Tire Height and Width for Use with a Timbren Offroad Axle-Less Trailer Suspension System
  • Since you are building an off-road trailer you would want the Timbren Heavy-Duty Axle-Less Trailer Suspension # ASR2KHDS02. This comes with a longer spindle to let you use a wider wheel and tire than the Timbren Axle-Less Trailer Suspension System with Hubs # A20RS545 that you referenced. The max height of the wheel and tire would only be limited by a fender and where you chose to install it. For a max width you have plenty of room there to. From the hub face to the trailer frame you...

  • Trailer Wheel for a 15 by 5 Inch Wheel with a 5 on 5-1/2 Bolt Pattern
  • With a bolt hole measurement of 3-1/4 inches on a 5 bolt pattern that would mean you have a 5 on 5-1/2 bolt pattern. We have one wheel with that bolt pattern, # TTW550555WS1. This wheel has a pilot hole that measures 4-1/4 inches in diameter. If your existing wheels center on the hubs using wheel bolts and not lug nuts then this wheel will not work. If it uses lug nuts then you can use this wheel because having a larger pilot hole is fine. With this wheel size you will need to use an...

  • What is the Capacity of a 15x6 Inch Trailer Wheel with 5 on 4-1/2 Bolt Pattern
  • There are different capacities depending on the wheel. For 15x6 wheels with a 5 on 4-1/2 bolt pattern we have the following capacities: # AM20522, # AM20537, # AM20524, and # AM20551 are rated for 2050 pounds at 75 psi # AM20504 is rated for 1820 pounds at 75 psi # AM22627 is rated for 2150 pounds at 65 psi You would not use passenger vehicle wheels on a trailer. They are not rated for that application and often the offset and/or bolt pattern is not right for a trailer.

  • What Size Trailer Wheel Will Fit a 7.00 x 15 Inch Tire
  • The closest size to a 7.00x15 tire would be a 225/75-15. These tires can fit on a 6 to 7 inch wide rim. But they are a little taller at 28.4 inches versus 27.88 for a 7.00x15. So basically, going to a 6 inch wide rim would be ideal. The black steel wheel that you have referenced, # AM20504, is a 15x6 inch with a 5 on 4-1/2 bolt pattern. But it also has a positive 5mm offset meaning the tire will be closer to the trailer frame by 5mm. You would have to make sure you have the available...

  • Will the Baby Moon Center Cap Fit a 15 Inch Wheel on a 1938 Chevy Master Deluxe
  • You should not have a problem using the Americana Baby Moon Trailer Wheel Center Cap, # AM90086, with the 15 inch wheels on your 1938 Chevy Master Deluxe as long as the wheels you are using are the standard steel car wheels. This cap is designed to fit 13 to 15 inch conventional steel wheels with a 5-lug pattern. There should be a ring that sticks out surrounding the bolt holes. This cap will snap around the outer edge of that ring. I have attached a photo showing the ring I am...

  • Availability of 15-Inch Wheels With 5-on-4-1/2-Inch Bolt Pattern
  • The wheels you referenced, Dexstar 15 x 6-inch wheel # AM20504 and 15 x 5-inch wheel # AM20404, both feature the 5-on-4-1/2-inch bolt pattern. These wheels also feature 3 projections around the hub area to allow a friction-fit of a hub cap like the 9-1/2-inch Americana Baby Moon # AM90086 for example. Since these wheels are not designed for use with any specific hub cap the fit of this particular Americana part, or your original hub caps, cannot be absolutely assured. I did go to...

  • What is the Weight Limit of the Dexstar Conventional Steel Wheel # AM20504 for a 7000 lb. Trailer
  • The Dexstar Conventional Steel Wheel + 1/2 inch Offset - 15 x 6 inch Rim - 5 on 4-1/2 - Black, item # AM20504, has a weight capacity of 1870 lbs. and would work great on your 7000 lb. GVW trailer. The only concern is the 1/2 inch positive offset of the wheel. Most trailer wheels and tires have a 0 offset which means that the part of the wheel that bolts to the hub is centered in the wheel. Trailer wheels are designed this way to carry the loads required of them. The 1/2 inch positive...

  • Black 15 Inch Wheels with 5 on 4-1/2 Bolt Pattern and 2-5/8 Inch Center Hole for Cronkite Trailer
  • We have a 15x5 inch, # AM20404, and a 15x6 inch, # AM20504. Each of these wheels has a 2.62 pilot hole. Each has the 5 on 4-1/2 bolt pattern. And each has a 1/2 inch positive offset. So the mounting surface is closer to the outside of the wheel moving the tire and wheel closer to the trailer frame. I have linked video reviews of both wheels for you. Based on the measurements I believe you need the 15x6 inch version, # AM20504.

  • Spare Tire and Wheel Recommendation for a Livestock Trailer
  • For that tire size you will need a 16 inch rim with a width range of 6-7-1/2 inches. It sounds like you have a 6 on 5-1/2 inch bolt pattern (check the FAQ article to confirm this) so I would recommend you get a Dexstar Conventional Steel Wheel # AM20758. This is a black, steel rim that is 16 inches in diameter and is 6 inches wide, as well as seemingly has the right bolt pattern you need. Check out the FAQ article on determining bolt patterns to confirm your bolt pattern. I would...

  • Will an ST205/75D15 Tire Fit on a 15 x 5 Inch Wheel
  • Yes an ST20575D15 tire will fit on a 15 x 5 inch wheel # AM20404. Any given tire size has a range of wheels it will fit. For this particular tire size it will fit 15 x 5, 5-1/2, 6, or 6-1/2 inch wheels. A 15 x 6 inch wheel would be more ideal, # AM20504.

  • Solution for a Trailer Where the Tires Rub the Frame
  • We don't recommend using wheel spacers to give a wheel more backspacing for trailer frame clearance. The real solution you need is to go with a longer axle. Nearly all trailer wheels have either a zero offset or very close to a zero offset so none of them would have the backspacing or offset you would need. A longer axle will push the hubs out further and will allow the rims to fit without trailer clearance. I attached a page that has all of the trailer axles we offer. We don't have...

  • Using Americana # AM22691 Aluminum Star Mag Wheels on 1928 Ford Model A
  • The only 15 inch wheel we offer that I can recommend using on a motor vehicle would be the Americana Conventional Steel Wheel, part # AM20504. This is a 15 x 6 inch rim with a 5 lug on 4-1/2 inch bolt pattern. The offset is +0.5, which means that the mounting surface of the wheel sits outside of the rim centerline by 1/2 an inch. For the front, we have the same wheel in a 5 inch width, part # AM20404. These wheels have the same offset. The # AM22691 wheel you referenced is a great...

  • Can Trailer Tires be Moved Further Away from the Trailer Frame
  • A wheel with an offset has the mounting surface off center so that the tire will be either closer to the trailer or further away depending on if it is a negative or positive offset. Positive offset means that the tire will be CLOSER to the trailer. Negative offset means that the tire will be FURTHER from the trailer. It sounds like you want a negative offset to move the tires a little further away from the trailer. But if the current set up is not making contact with the frame then...

  • Replacement Wheel and Tire Recommendation for a 1998 Nitro Trailer
  • For a 14 inch rim with a 5 on 4.5 inch bolt pattern similar to the one you referenced you would want the part # AM20304. For a tire in the size you have to use as a spare you would want the part # AM1ST90. The pilot diameter of the wheel I referenced is 2.62 inches. This shouldn't matter as long as your wheel is attached with lug nuts and not wheel bolts.
