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"

Shipped and arrived as expected. Looks just like the picture, only bigger ;-) Forgot to order valve stem with the rim, but any place that sells me a tire and mounts it should have one that will work.46264

  • 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 offset w

  • 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 space be

  • 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 wheel

  • 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, # 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 an ST205/

  • Tires and Wheels for a 1995 Nitro F/S Boat Trailer
  • Not knowing the original tire size will make this a bit more challenging, but it can be done. If you can provide more information about your trailer, it would make choosing the correct wheel/tire combo easier. The following would be very helpful- The bolt pattern of your hubs (see FAQ article) The axle or trailer capacity (should be listed on a plate or sticker somewhere on the trailer) Center of spindle to inside of fender measurement My hope was that with the serial # or VIN from

  • 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 recomm
