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"

White power coated, 8" steel wheel features a 4 on 4 bolt pattern and meets Department of Transportation standards.


Great wheels. I used them on my Steiner tractor and they fit perfectly. I paired them with bar tires and have had 0 issues.


Used these wheels on a atv trailer build several months ago. Worked great!


Tire rim works good, fits well, no comp laints



Got exactly what I paid for , Very happy.


Pretty nice wheels. Paint was chipped a bit but their for a Toro zero turn mower. Thank you!


These wheels worked well for my application -- my Toro ZTR lawn mower. Due to getting stuck with the wimpy stock turf saver tires, I decided to replace them with something with better traction. The aggressive tires I chose required wider wheels than stock to work. You can't beat the price of these wheels. Toro sells these types of wheels online for $87+/wheel and these were $17/wheel. ...Well that's a no brainer! My purchase went smooth and this company's communication was excellent.

Kevin R.


What size tire did you put on these wheels?

Leon R.


Carlisle Super Lug Lawn


Great golf cart wheels


It's not what I think it's what I know and what I know about your staff is that they are very knowledgeable in their job and very helpful in which it would make me a repeat customer when I need help with purchasing any other rims So please Thank your staff and warehouse workers for they were FABULOUS


They look great and function very well. No more spinning tires and loss of traction while cutting grass.



The tires & wheels are great!


I have had this tire and rim for a year and use it alot. Reliable for sure


Worked great on my Hustler mower


Bought a used yacht club trailer to haul my pulling tractor's around. Figured I would look for new rims for it and found these. Great price. Fast shipping and well packaged. Have not mounted them, but will get a updated photo when I do


A big Thank You! to George, Kurt and Steven for processing, pulling and packing this order.

Wheels are excellent, well made and DOT approved. Their size is clearly stamped into each wheel and the finish is a gloss white that looks to be heavy/thick and should last for years on trailers, lawn carts and lawn equipment. I'll be using some of these for those applications as well as GoKarts and Minibikes.

Everything was packed well and arrived in perfect condition. Each wheel was isolated from the others and well protected from shipping damage.


Exact match to my old rims, nice paint finish, exactly what I was looking for.


Top quality product that was well packaged and arrived on time


These are perfect! I got them for my Husqvarna zero turn mower and some aggressive tires I picked up. Wow, I can't believe how affordable the rims are! They fit, they look great, and I will be recommending anyone who asks about them to etrailer.


I got this replacement wheel for my zero turn mower. Fit perfectly. Fast shipping!


Quick and reasonable shipping. Quality wheels at a value price, and I was in the tire industry for 42 years. Not all of your products are going to end up on a trailer, we have 8 of your wheels on 2 of our go kart buggies. My grandson liked the finish on these wheels so much we left them white and did a black and white paint job. Just waiting for nicer weather to go ride.


I build custom trailers for hunters to pull behind their 4 wheelers. Your wheels are a nice clean touch to the finished product.


Just what I was looking for. They go good with my 9.5 inch wide tires. Gives my utility trailer more stability. I would definitely recommend etrailer products to anyone. Thank you.


The customer support is excellent from the ability to reach a live, knowledgeable, and friendly staff member as well as the informative videos and chats they post. No doubt one of the best sources for these trailer related parts. Wish they carried the Load D tires I was looking for as had to go elsewhere for those.


I am very satisfied with product and derived in a timely matter. Will do more business here


Parts ordered were delivered on time with no issues.


Perfect! Fast shipping looks great just like the picture and most importantly, works exactly as it should.Excellent follow up from customer service keeping me informed of the status of my order.8x7 4on4 rims


Fit my Dixon ZTR Classic perfectly. Mounting the tires was a breeze. Great quality wherls


Well it is certainly a breath of fresh air to have high quality human service again. I love the tech you employ for tracking a shipment. Well Done! I really loved the free shipping as well. The packaging was first rate. I ordered some rims and they must stay rounded so they must be properly protected. Well Done! You can all be Proud of what you are doing and how you are doing it. Thanks !!

  • Is There a 215/60-8 Load Range D Bias Trailer Tire & White Wheel With 4 on 4 Bolt Pattern
    There is an option for a 215/60-8 load range D bias trailer tire and 8" white wheel with a 4 on 4" bolt pattern, but they come separate so you'd need to get the tire mounted to the wheel. The correct parts for this are the following: - Loadstar K399 Bias Trailer Tire - 215/60-8 - Load Range D # AM1HP28 - Steel Trailer Wheel - 8" x 7" Rim - 4 on 4 - White # AM20021 Then for the valve stem you will need the Americana High Pressure Rubber Snap-In Valve Stem # AM20904. This tire has a 1,165...

  • Trailer Tire Recommendation for a 8 inch by 7 inch Steel Trailer Wheel # AM20021
    The most popular tire we carry that people get with the Steel Trailer Wheel # AM20021 that has been confirmed as a fit is the Loadstar K399 Bias Trailer Tire # AM1HP28.

  • Looking for Replacement 8 Inch by 7-1/2 Inch Wheels for a Toro Zero Turn Mower
    We have some 8 inch by 7 inch wheels, # AM20021, but none that are 7-1/2. You might be able to use the 8 x 7 inch wheels but you would need to determine if the tire size is compatible. Any given tire will fit a range of wheel widths so it is entirely possible that the tires for your Toro will fit the 7 inch wheels.

  • Is the Americana 8" x 7" Trailer Wheel With 4 on 4 Bolt Pattern Available in Black
    I may have a solution, but the # AM20021 are not available in black powder coating. However, the # AM20023 is the exact same wheel, only it's a galvanized steel wheel without any powder coating; you could potentially just have them powder coated to match your application.

  • Replacement 8" x 7" Wheel and 18x9.50-8 Size Tire Needed for a 1991 Cushman Turf Truckster/Haulster
    From what you referenced it does sound like the Steel Trailer Wheel # AM20021 is what you are needing! It is an 8" x 7" wheel that has a 4 on 4 bolt pattern and a 1,165 lbs weight capacity. Although we don't have an 18x9.50-8 size tire we do have the Loadstar K399 Bias Trailer Tire # AM1HP28 which slightly smaller than your current tire. The outer diameter for this tire measures 18.1" and it has a section width of 8.9". The load range is D (1,165 lbs at 70 psi) with a speed rating of 65...

  • How To Find Correct Replacement Wheels and Hubs for Triton XT10 Enclosed Snowmobile Trailer
    I do likely have some options for this trailer but we don't have any way to look up what parts it uses therefore you need to provide some information, namely the axle capacity which should be stamped onto the tag in the center of the beam. It likely uses 2,000 lb axles and in which case you would be looking at either the Trailer Idler Hub Assembly part # CE13110 for 4 lug or part # AKIHUB-545-2-LF-1K for 5 lug. If you have a different capacity you'll need to look through our list below...

  • Replacement Steel Rim For Hustler Super Z Lawn Mower
    We may have the wheel you need for your Hustler Super Z Mower, but the wheels we offer are not designed specifically for your mower. I have attached a link to our 12 inch wheels. You will need to know what the wheel bolt pattern is and whether an offset is required for your mower. You want to make sure you select a wheel that will also fit the pilot hole on your mower. You can use the filters on the product page to find the wheel you need. I have also attached a helpful article that explains...

  • Backspacing for the Americana Steel Trailer Wheel # AM20021
    The Steel Trailer Wheel # AM20021 has a backspacing of 3-3/4". On a typical trailer wheel you would just add an inch to the width of the wheel and then divide in half but since this wheel is wider than most trailer wheels the backspacing is slightly different.

  • What is the Offset and Backspacing of Dexstar 8x7 Inch Trailer Wheel with 4 on 4 Bolt Pattern
    First, I can tell you that we carry few rims that have an offset. If it did have an offset it would be listed so it looks like the Dexstar Wheel, # AM20021, has a zero offset. Given that it has a zero offset the total width of the rim is 8 inches (7 inches bead to bead plus a 1/2 inch on each side for the lip). That would make the backspacing 4 inches (distance from rim lip to mounting surface). I went out to the warehouse and pulled one of these wheels to be sure. It did have a backspacing...

  • Can Modern 8" Diameter Wheels Work With 7" Drum Brakes On Trailer?
    I wish it would, but the Steel Trailer Wheel - 8" x 7" Rim - 4 on 4 - White # AM20021 you were looking at will not work with 7" drum brakes as the I.D. of the wheel is closer to 6". It may be possible to find an extra wheel like your current wheels on a resale website. Instead the only modern option I am aware of is going with the 10" or larger wheel like the Steel Trailer Wheel - 10" x 6" Rim - 4 on 4 - White # AM20041. I included a video of the # AM20041 for you to take a look at.

  • Do You Carry Rims For a 18.5x8.5-8" Trailer Tire?
    We have an 8"x7" rim with either a 4 on 4" # AM20021 or 5 on 4-1/2" # AM20026 bolt pattern. Both these wheels fit the 18.5x8.5-8 tire size you have on your snowmobile trailer.

  • Recommended Wheel to Use with 20x10.00-8 Size Tire
    For your 20x10-8 size tire, you can use an 8 inch x 7 inch wheel like the Americana # AM20021 if you have a 4 on 4 inch bolt pattern or # AM20026 if you have a 5 on 4-1/2 inch bolt pattern. Both wheels feature a nice white powder coat to resist corrosion and a sturdy steel construction. I have attached a couple of short video demonstrations on these wheels that you can also check out.

  • Would These Wheels Work on a Zero Radius Turn Mower?
    The wheel you mentioned has a 900 lb weight rating, so the capacity will not be your problem. The wheel size is the same, but I am not entirely sure that the bolt pattern will be close enough to match up. A 4 bolt on 100mm bolt pattern would equate to 4 on 3.94 inches, which would be far enough off that it would not fit. The # AM20021 is for 1/2 inch wheel studs and has a 2.5 inch pilot diameter. I would recommend confirming the bolt pattern of your hubs, I have linked you to an FAQ...

  • Will Americana Steel Trailer Wheel # AM20021 Work on TXT Ezgo Golf Cart
    As long as the hubs on your TXT Ezgo Golf Cart feature a 4 on 4 inch bolt pattern and its 8 inch x 7 inch dimensions match what you currently have the Americana Steel Trailer Wheel # AM20021 will work great. This particular wheel is commonly used on golf carts or lawn mowers and it has a robust 1,165 pound weight capacity. I have attached a short video demonstration that you can also check out.

  • Trailer Rim Availability that is 8 inches in Diameter, 7 inches in Width and has 4 Bolt Pattern
    For a trailer wheel that is 8 inches in diameter that has 7 inches of width and a bolt pattern of 4 on 4 inch we have the part # AM20021. As long as your current wheels have a zero offset like this wheel it would clear your frame the same way. To help equalize the load that a trailer wheel carries manufacturers almost always give trailer wheels a zero offset of one very near it. For a version of this with a tire on it that is sized 215/60-8 you would want the part # AM3H290.

  • What is The Mounting Offset For the 8" Steel Trailer Wheel # AM20021?
    The Steel Trailer Wheel # AM20021 has 0 offset so the mounting flange is at the center of the wheel. Do understand the wheel size is 8" diameter and 7" wide but these measurements are for the bead seats inside the lips of the wheel. The lips for each bead seat on this wheel are going to add approximately 3/8" to both the height and width of the wheel so you innermost part is going to be 3-7/8" from the mounting flange for the outer lip.

  • Will A 20x10x8 Tire Fit On An 8"x8.5" Wheel
    Yes, a 20x10x8 tire would fit on a 8" x 8.5" wheel. Generally as long as the tire's last number which is the rim size is the same as the size rim your trying to install the tire on it will fit.

  • 215/60-8 Trailer Tire and Wheel Combo with a 4 on 4 Bolt Pattern
    Take a look at Kenda 215/60-8 Bias Trailer Tire, # AM3H290. It is the same size and a load range C rated for 935 pounds at 50 psi. It has a 4 on 4 bolt pattern. In this size, 215/60-8, there are only 5 on 4-1/2 and 4 on 4 bolt patterns. I have included a link to our tire FAQ article for you. For an 8-ply tire, there is no combo available with the tire already mounted on the wheel but you can get # AM1HP28 and wheel # AM20021 and have a local tire shop mount the tire on the wheel.

  • Availability Of Trailer Hubs/Wheels With 4 By 156 mm Bolt Pattern
    I am sorry but we do not carry any axle hubs that use a 4/156 mm bolt pattern, nor do we carry any kind of adapter or conversion kit that will work for this purpose. The only solution we can offer is to get new wheels that use the standard 4 on 4 bolt pattern. We have 4 on 4 wheels available in sizes from 8" # AM20021 all the way up to a 13" # AM20202.

  • What Size Tire Pairs With The Americana 8" x 7" Steel Wheel?
    The tire typically paired with the 8" x 7" steel wheel # AM20021 will be the Kenda # AM1HP26. This is a 215/60-8 tire with a load capacity of 935 lbs at 50 psi and has an M speed rating (81 mph), both of which should be more than enough for a mini bike build. When inflated the tire will measure 8.9" wide and 18.3" in diameter. You will also need a valve stem like # AM20903 as the rim does not have one included. If you would like, these all come preassembled as part # AM3H290.
