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"

Fast shipping!! I'll be back again Thank You

Great!! Prices are unbeatable!!
Steve - 10/26/2022


These wheels have been good so far, especially for the price. Mounted brand new Taskmaster Contender tires on these wheels when I got them. The tire place did mention they were surprised how much weight it took to balance them since they are made in the USA wheels but they did balance fine and I've not had any issues, maybe they just said that because I didn't buy them from their store, who knows.


Perfect fit. The wheel I was looking for, I could only find it on


Made in America, a great quality product not imported sub par
Junk. Thank you for providing this item.


Other than a few blemishes on wheels, and some chipped powder coating, the wheels work great and look good!

Better than imagined. Still very firm!
Mark W - 09/16/2020
Still looking good! Must keep chips touched up, or rust will form quickly! Great Product!
Mark W - 09/16/2020


Nothing wrong with these rims just two items I noticed that emphasize you get what you pay for....1. I plan to paint the back side of the rims before installing them. When received the exterior side was coated well but the inside (side facing the trailer) was not completely coated with paint. 2. The plate where the lugs touch is perfectly flat. That will work but a higher quality rim would have some dimples in the plate to add springiness and would act to keep the lugs torqued. The capacity of the rims (both load carrying and psi) are not stamped or written on the rims anywhere. I hope nobody needs to know that information down the road.

Shipping was extremely quick and they were well packaged so gets an A+ for their effort.

Rims are working fine, no problems to date after a year.

These wheels look great on my trailer I pull behind my 23T roadster. Thanks, cory


Super fast shipping and exactly what I needed.


The powder coat was chipped on all of the wheels. It is ok but I would have liked them undamaged.


Price is good, quality is good. Happy with product. Product arrive in great shape because they took the time to package wheels with paper and cardboard. Wheels arrived not scratched or shipped.


Looks great match's other spare on fifth wheel(8282ws)


This is a nice wheel, a great upgrade from the small 4.8x12 tires. I have three of these wheels. Single axle with full size spare. Running a 225/75r15.


Powder coating is even on all surfaces. Packaged well. Hopefully will hold up better than the wheels that I purchased elsewhere.


I recieved my tires and wheels yesterday. I was in need of these quickly since I was leaving on a trip the same week. Dana M. at etrailer hooked me up with the right tires and wheels for my trailer and the shipping was as promised. Thank you guys for a great transaction. I would definitely buy again.


had to order new rims for my horse trailer. Th
E website was very informative about the identifying the bolt spacing, rim width, center bore dimension, etc. The rims arrived promptly, and they fit perfectly.


I wanted the 15 inch rims to allow a higher capacity tire to be installed on my rv.
You offered an American made product from a well know company at a very competitive price and useful advise on making the upgrade. Could not be more satisfied with the product and service.


The ease of ordering and customer service we received was very good. We are in some unprecedented times, and when I called because I was worried we would not get the wheels in time for our installation appointment, my concerns were met with a caring attitude. We set our appointment out two weeks from the order date, but the warehouse was backed-up on filling orders. With in a day of calling our order was shipped and received in plenty of time so that we were able to keep our appointment. The wheels were in perfect condition. Thank you!


Looks like a good quality rim. Fit well and should give plenty of good service in years to come. Used for a "rebuild" on a 1976 vintage utility trailer.

They are holding up to use well. Good product at a good price
Bill - 08/27/2020


Ordered a trailer wheel online, got confirmation of order in minutes, wheel arrived 2 days earlier than expected. correct part and great product!


Ordered three wheels on Wednesday evening, 2/26/2020 at 7:52pm. I was notified the order shipped at 9:39pm. approximately 1 hr. and 30 minutes later. They arrived on Friday 3/28/2020. What great service. They were exactly as advertised and I would certainly order from them again.


Excellent service and fast delivery even at Christmas time. From Missouri to Idaho


Very well made, fit just like the one that I replace. I would recommend this product to anyone looking for a strong well made wheel. Plus it's made in the USA.


Exact replacement for my 2001 Pace Trailer. Purchased 11/2018. Excellent wheels.


The rims are very good. One more coat of paint would make them better. etrailer's Customer Support is great. Delivery was super quick. Thanks.


Bought a set of 4. Perfect for my ATV trailer. They made my trailer look new.

  • What is the Backspacing and Offset for Dexstar 15x6 Inch Trailer Wheel with 5 on 4-1/2 Bolt Pattern
    Backspacing and offset are two different things. Dexstar wheel # AM20551 has a zero offset meaning the mounting surface is centered. The width is 6 inches, but that is measured bead seat to bead seat not overall width. That means that the overall width is approximately 7 inches making the back spacing approximately 3-1/2 inches. This wheel has a 5 on 4-1/2 bolt pattern. Make sure your hub has the same bolt pattern. I have included a link to the right on how to determine bolt pattern.

  • Availability of 15" Trailer Wheel with Backspacing of Less Than 3"
    All of the 15" trailer wheels we have available will have an backspacing of greater than 3 inches. This is because trailer wheels have either a zero offset or one that is very minimal, which allows the tires/wheels to stay evenly balanced under a trailer's weight. We definitely don't recommend using spacers to give you the needed fender clearance so your best option is honestly going to be with a longer axle. It sounds like maybe the trailer was home built and wasn't designed perfectly...

  • Is Dexstar Mini Mod Trailer Wheel Lug Centric?
    The Dexstar Steel Mini Mod Trailer Wheel # AM20551 is lug-centric, as are the majority of trailer wheels. This means your tires will need to be balanced at a tire shop that has a pin plate adapter.

  • Availability of White Mod Trailer Wheel with 15 inch Diameter and 5 on 4-1/2 inch Bolt Pattern
    The closest match we have that is close to the weight limit you need will have to be a 15 inch by 6 inch wide wheel since the 15x5 wheels have capacities closer to 1,800 lbs. The part # AM20551 is a white mod wheel with the bolt pattern you need and a 2,150 lb weight capacity.

  • Looking for 15 x 6 Inch Wheel with 3 Inches of Back Spacing
    A 3 inch backspacing on a 6 inch wide wheel is the same as a zero offset, where the wheel mounting pad would sit right at the centerline of the wheel's width. The Dexstar # AM20551 Mini Mod 15 x 6 wheel you'd looked at has a zero offset, which would give it 3 inches of back spacing. The wheel has a 5 on 4-1/2 inch bolt pattern. If you click the provided link, you can see a product description video featuring the # AM20551 Mini Mod wheel you'd looked at.

  • Max Pressure for Dexstar Mini-Mod Trailer Wheel AM20551
    The psi rating for a wheel is normally limited by the valve stem installed in the wheel. But in this case Dexstar states that this wheel is rated at 80 psi. The valve stem hole for Dexstar wheel # AM20551 is 0.45 inches in diameter. The wheel is rated for 2,050 pounds at 75 psi so valve stem # AM20904 would fit. It is rated up to 80 psi.

  • Valve Stem Hole Diameter for Dexstar Steel Mini Mod Trailer Wheel - 15 x 6 Rim - 5 on 4-1/2
    The valve stem hole for Dexstar wheel # AM20551 is 0.45 inches in diameter. The wheel is rated for 2,050 pounds at 75 psi so valve stem # AM20904 would fit. It is rated up to 80 psi.

  • Recommended Wheel and Tire to Replace 7.00 x 15 Tires on 1978 Holiday Rambler
    For a 15" tire I recommend the Karrier ST225/75R15 Radial Trailer Tire - Load Range E Item # AM10303. Then for the wheel, you could go with the Dexstar Steel Mini Mod Trailer Wheel - 15" x 6" Rim - 5 on 4-1/2 - White Powder Coat, Item # AM20551 or something similar. We do not have this combination premounted. You would have to have them mounted at a local shop. This wheel/tire will be comparable size to the old tires and they have a 2830-lbs per tire capacity, so they should provide...

  • Availability Of 15" Trailer Wheels With 5 On 4-1/2 Bolt Pattern
    It sounds like you are looking for 15" wheels with the 5 on 4-1/2 bolt pattern. We have quite a few wheels that fit this description, but out of them I recommend taking a look at the Dexstar Steel Mini Mod Trailer Wheel - 15" x 5" Rim - 5 on 4-1/2 in Black # AM20440, Silver # AM20537, or White # AM20551. If you can tell me which tire size you are planning on using I would be happy to make sure the wheels mentioned are the correct width for your application. I included a link to all of...

  • Replacement For Dexstar 15 Inch Wheels 017-232
    There are Dexstar 15" x 6" wheels with a 5 on 4-1/2" bolt pattern and round openings (called mini mods), and are model 017-232, but without any pinstriping. So they are the exact same thing but for that pinstriping, and are available in three different colors - white, silver, or black: - White: Dexstar Steel Mini Mod Trailer Wheel - 15" x 6" Rim - 5 on 4-1/2 # AM20551 - Silver: Dexstar Steel Mini Mod Trailer Wheel - 15" x 6" Rim - 5 on 4-1/2 # AM20537 - Black: Dexstar Steel Mini Mod...

  • Recommended Tire/Wheel Combo Upgrade From ST205/75R15 to ST225/75R15 Load Range E
    Upgrading from a ST205/75R15 to a ST225/75R15 is a very common upgrade on trailers as long as you have the clearance. The ST225/75R15 tires are only about a 1" wider and taller compared to the ST205/75R15. The general rule is you want to keep 3 inches of vertical clearance above the top of the tire to allow for normal travel of the trailer's suspension and 1-2 inches of clearance between the tire's sidewall and the closest part of the trailer. We don't have this combination pre-mounted,...

  • How Strong Is The Painted Finish Of The Aluminum Viking Series Vor Trailer Wheel AX02550545FPS?
    The Aluminum Viking Series Vor Trailer Wheel - 15" x 5" - 5 on 4-1/2 - Silver # AX02550545FPS has a silver painted and clear coated finish which is pretty resistant to rocks and debris like you mentioned, but is not the toughest finish. You would be better suited with a powder coated wheel like the Dexstar Steel Mini Mod Trailer Wheel - 15" x 5" Rim - 5 on 4-1/2 - Black Powder Coat # AM20440, White Powder Coat # AM20551, or Silver Powder Coat # AM20436. Powder coating is actually baked...

  • 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 and # AM20524 are rated for 2050 pounds at 75 psi # AM20504 is rated for 1820 pounds at 75 psi # AM22627, # AM20551, and # AM20537 are 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.

  • Is the Westlake ST235/75R15 Radial Off-Road Trailer Tire Good For Long Highway Trips?
    You are safe staying with your Westlake ST235/75R15 Radial Off-Road Trailer Tire # WST54FR as long as it is not damaged or showing signs of dry rot due to sun damage. As this tire has a radial construction it will perform well on the highways. It is very smart having a TPMS # TM89FR to monitor the tire pressure and temperature during your trip. This will help you in the event of a flat before the tire has a blowout and damages your trailer. I do recommend bringing a spare Wheel # AM20551...
