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 - 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 - 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 - Side

Measuring the distance (D) 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"

  • How Can I Identify an Axle Without a Sticker?
    Thank you for the pictures! It looks like you've got some sort of square drop axle on your trailer and if you can't find an identifying sticker, I can still help you figure out what you've got so that you can make the swap to electric brakes on your trailer. It looks like you've got 6 bolts on the wheels, which can help narrow down our search, but we'll need to know what size the brakes on the trailer are and if possible, what size (or number) the inner and outer bearings are on the hubs. If...

  • Tips for How to Identify a Trailer Axle
    Depending on how the trailer was made, there will be a few spots you can check to identify the axle. First, if the trailer was pre-made by a specific company, you may be able to find this information in either the paperwork or on a placard somewhere on the frame. Sometimes, the axle identity is stamped into the axle itself or into the hub if it was purchased as a complete assembly. If you cannot find any markings or notation for the axle, you will need to look for replacement parts based...

  • What is the Weight Capacity of a Dexter SLR P16 Axle
    If you can read me the serial number on the axle I can then call the manufacturer, Dexter, and find out the weight capacity but if not you can measure the diameter and use the chart below to determine axle capacity. The "P16" is the plant it was made. - 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter - 3,500-lb Axles: 2-3/8 inch diameter - 6,000-lb - 7,200-lb Axles: 3 inch diameter - 8,000-lb Axles: 3-1/2 inch diameter - 9,000-lb Axles: 4 inch diameter - 10,000-lb + Axles:...

  • How to Determine Dexter Axle Weight Capacity
    I reached out to my contact at Dexter and they don't have any information based on that serial number in their system. They recommended taking off one of the wheels and on the hub there will be a number that starts with 8 followed by a dash and then 3 more numbers. We can help with axle capacity based on that number. As far as camber, all through axles will have a slight bow in the middle which would appear to be a camber when unloaded but they do even out when under load so there...

  • Can I Guess or Estimate Axle Weight Capacity By Number of Lug Nuts
    I do have a few easier options for you to determine the weight capacity of an axle other than using the bolt pattern or the number of lug nuts. The problem with using the bolt pattern to tell the axle capacity is that an axle may have the a bolt pattern that could be more than one weight capacity. The easiest would be to look on the trailer VIN plate or sticker that lists the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could...

  • How To Determine the Weight Capacity For a Trailer Axle
    The trailer will have a plate or sticker on it that will list the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that will list the weight capacity. You can also tell the weight capacity of the axle by measuring the diameter of the axle. Here is a list that will show the axle weight capacity based on the axle diameter: Typical Axle Diameters Based on Axle Capacity - 1,000-lb - 2,000-lb Axles: 1-1/2...

  • How to Determine the Weight Carrying Capacity of a Flatbed Gooseneck Trailer
    I would not automatically assume your trailer has a weight capacity of 20,000 lbs or more with two 10,000 lb axles. You must also consider the weight of the trailer itself and the Gross Vehicle Weight Rating (GVWR) of the trailer. The GVWR is the maximum weight that your trailer can weigh when it is loaded. This should be listed on the identification or specs plate on the nose of your trailer. The best way to determine the load capacity of your trailer is to subtract the weight of the...

  • Does the Tongue Weight of a Trailer Get Transferred to the Rear Axle of a Truck
    A trailer with 280kg (617 pounds) tongue weight would exert less than that weight on the actual rear axle of the tow vehicle. There isn't a calculator for this because you also have to take into account suspension components which transfer weight to the frame and only a portion of that gets transferred to the axle. The best way to get a good estimate of how much weight is on the rear axle is to use a scale that can be placed just under the rear wheels. Then you could weigh the tow vehicle...

  • How to Remove Trailer Wheel that Doesn't have Lug Nuts or Bolts
    Thanks for the photo. To remove the wheel that doesn't have lug nuts and bolts, you will need to remove the cotter pin that holds the wheel in place. Bend the two prongs up to straight and then push that end through the spindle. That wheel and tire should be replaced so you can have matching hubs with the same bolt pattern moving forward. To get matching hubs, check for numbers on the hub or get the bearing number from the face of the inner and outer bearings on the side with the...

  • Does a Trailer with Two 3,500 Pound Axles have a Gross Capacity of 7,000 Pounds
    Most likely, the trailer would be rated for 7,000 pounds gross if it has two 3,500 pound axles. But there should be a sticker or plate somewhere on the frame near the front of the trailer that lists its official capacity. Also, the trailer can only be rated as high as the lowest rated component. So for example if the coupler is only rated for 6,000 pounds and everything else is rated at 7,000 then you have to go by the 6,000 pound amount.

  • Can the VIN of a Boat Trailer be Used to Determine Age of Trailer
    Typically the 10th digit of a trailer VIN is the year the trailer was manufactured. I attached a picture that shows a VIN decoder for trailers for you to check out as well. You can also give the VIN to the trailer manufacturer and I am sure they will be able to fill you in on all of the details as well.

  • Hubs to Use With Kodiak Disc Brake Kit K2R526DKG
    Since the Kodiak Disc Brake Kit part # K2R526DKG is a slip on disc brake kit you would need an idler hub like the part # AKIHUB-655-6-EZ-K which is a 6k hub and has the correct 6 on 5-1/2 inch bolt pattern. We don't have a Dexter hub in this configuration but the etrailer hub I mentioned would work really well and is also pre-greased with LMX red grease too for an easier and cleaner install.

  • What Info is Needed to Pick Out Replacement Axles for Trailer
    Hey Mark, to pick out replacement axles we need a few pieces of info to make sure we get you the right ones. We need the distance from hub face to hub face on your current axle as well as the distance between the spring seat centers. With that we can see what axles would fit as well as what capacities we have available too. You should keep in mind that we can't get every axle configuration so there's change you'll have to source them from a local trailer shop. I attached a link to all...

  • Boat Trailer Tires are Wearing On the Inside Tread
    Generally when tires bow out at the bottom, in at the top, that indicates that the trailer is overloaded. If you are within the 2,000 pound capacity though this should not be happening. If the axle was ever flipped upside down, like to gain more height, that can cause this same issue. Axles should not be flipped because they have a bow in them. A flipped axle will have the bow facing the wrong way and it diminishes the capacity of the axle. Also, worn suspension components can cause...

  • Which Axle for Homemade Trailer
    You'd be best off tailoring the suspension to the maximum weight you're planning on carrying. If you'll be carrying around 1100 lbs typically, I'd recommend going with a 2K axle/suspension. A one inch spindle is typically used on a 2K capacity axle, so that's likely what you have now. I'll link you to our selection of 2K capacity axles, some that include hubs. You'll want to choose an axle with the same hub face to hub face dimension and spring center to center distance (although spring...

  • Appropriate Axle Rating for Trailer Weighing 7680-Lbs When Loaded
    A trailer's axles must be rated for at least the maximum trailer weight, its GVWR, or gross vehicle weight rating. This is the most the trailer can weigh when loaded. Naturally it is advisable to have some safety margin too. The standard beam axles we sell have ratings up to 3500-lbs. Higher-rated axles are made, of course, but we do not ship them due to shipping size and weight restrictions. Two 3500-lb axles in a tandem axle set-up would not have enough capacity, but three 3500-lb axles...

  • Replacing A Damaged Axle On A 1997 Fleetwood Mallard 24J
    Hey Anderw, I can definitely point you in the right direction. Unfortunately, we do not have a way to look up your trailer to know what size and capacity axle you have currently. Do you happen to know the weight capacity of each individual axle? With a 6,000 lb GVWR it should be something like two 3,500 lb axles, but we will need you to verify this. We will also need to determine the hub face length, and spring center length of the current axle. If you are replacing just one axle on a...

  • Wheel and Tire for Tandem Trailer with GVWR of 16,450 lbs
    While we can't order you in the axle you are needing we can help with the wheels and tires. For the weight capacity you are going to need our best option is a 215/75R17.5 wheel and tire like the part # TA95ZR which has a weight capacity of 4,805 lb per wheel/tire. This has a bolt pattern of 8 on 6-1/2 inch which would be the bolt pattern the drums you'd order would have but you might double check when you order the axle just to be sure. Due to the spring seat dimensions you need and...

  • Recommend Replacement Tire for Limited Clearance on Mobile Home Axle
    The tire size you referenced, 8-14.5 has an overall diameter of 27.7 inches and a width of 8 inches. We do not carry a direct replacement. For a replacement wheel and tire package that will fit the # 8-201-5UC3 and the # 42655UC1 hubs with a 6 on 5-1/2 bolt pattern, we have the Karrier Tire and Wheel, part # AM32664. However this wheel and tire combo has an overall height of 28.4 inches and a width of 8.9 inches. You would need to measure to determine if you will have sufficient clearance. If...

  • Determining Axle Capacity for 2 inch Square Axles

  • Parts Needed To Install Timbren 5,200 Lb Axle-Less Trailer Suspension System
    In order to use the Timbren Axle-Less Trailer Suspension System part # TASR5200S03 you will just need an idler hub assuming you do in fact not want to use brakes of any kind. For this, the Dexter Trailer Idler Hub Assembly part # 42655UC1 will be an excellent match but aside from this nothing else will be needed besides the wheels, tires and lug nuts of your choosing. The hardware needed for installation is included with the Timbren Axle-Less Trailer Suspension System so you will be good...

  • Determining the Carrying Capacity of Trailer
    It is highly likely that you can carry 5,000 pounds on two 3,500 pound axles. The carrying capacity of two 3,500 pound axles is 7,000 pounds. The axles support not only the cargo's weight but also the weight of the trailer's frame and body. You will need to calculate the total weight of the trailer frame and body, also known as the dry weight, and subtract this weight from the axle's 7,000 pound capacity to find the weight the axles can carry. Then, you will want to add back the loaded...

  • Looking For Replacement 2,500 lb Axle For A 1997 Fleetwood Mallard 24J
    Hey Andrew thanks for the pictures. That axle tag has certainly seen better days. From what I can see it says Dexter Axle SLR 2500 lb. My best guess is the serial number says 1769444. Unfortunately, there is no way for me to determine the hub face length by looking at this tag. Your best bet will be to measure the hub face length and spring center length of the current axle. I will tell you up front that we do not offer any 2,500 lb axles so we do not have a direct replacement for this....

  • Why Are My Trailers Axles Under Rated For My Campers Dry Weight?
    Hello Melissa, thanks for reaching out. This is pretty typical for campers. The reason for this is about 15% of the total weight is tongue weight on the hitch (or the jack), so the axles are not bearing the full weight of the camper at any point.
