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. .

Hi Steve, I have the same truck as you, a 1954 3600 Chevy. Im also sick of these split rims, mine are 17 x 7.5. I want to replace them with a 16 chrome steel or aluminum wheel and get this truck a little lower to the ground. Now that you have the Dexstar wheels a while, how do you like them. Did their installation require any modification? Thanks for any advice you could offer. Keep drivin! Larry F.

Wheels arrived well packed. Just what I needed, in fact will be ordering two more next week! Plan on using these on my 51 Chevy. Tomorrow will attach hubcap clips so I can mount the original hubcaps. Glad I found this company. I'll be using them for all my trailer needs. 119738


Phil, did you buy the rims and, how do they fit? I also have a 51 GMC 3/4 ton and I am looking to buy the Dextar rims. I appreciate your feedback. Thanks.

David, rims fit my 51 3800 perfect. Im sure you will like them on your GMC. You can get the clips from most of the vintage truck vendors. Hope this helps!

Excellent wheels, perfect replacement option for 1954 Chevrolet 3600 (3/4 ton). Great fit with LT215/85R16s...1/2" clearance from the problematic factory tie rod ends. Original (dog dish) hubcaps fit the raised ring perfectly, just need to install the finger-clips to hold them. Best of all no more split rims!! 103382

Expert Answers about Dexstar Conventional Steel Wheel with Offset - 15" x 6" Rim - 5 on 4-1/2 - Black - AM20504Do you have a question about this Tires and Wheels?

  • 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...

  • 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 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.

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...

  • 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...

  • 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, # WHI155-555WS-T. This wheel has a pilot hole that measures 4-1/2 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...

  • For that tire size you will need a 16 inch rim with a width range of 6-7-1/2 inches.

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.

  • 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.

  • 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.
