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"

  • Wheel Fitment for 5/8" Studs on Disc Brakes
    Hey Fred, thanks for reaching out! The only wheel we have that work with 5/8" studs is from Dexstar as part # AM20790. This has a 5-1/2" offset and is designed for a dual wheel setup, so if you have something else you'll need to talk to a local trailer shop about ordering a specialized wheel.

    The Dexstar Dually Wheel part # AM20790 is a 16 x 6 inch wheel with an 8 on 6-1/2 inch bolt pattern and a center bore of 4.88 inches. It fits all your criteria mentioned so it would work well for you. Most popular tire we offer to fit this rim is the part # TTWPRG235R16. This is a 235/85-16 size tire.

  • Bolt Pattern of Taskmaster Steel Dual Trailer Wheel Item # AM20790
    First, 170 mm is 6.69 inches. The Dexstar Steel Dual Trailer Wheel - 16inch x 6inch - 8 on 6-1/2 - 4.88inch Pilot - Silver Item # AM20790 that you referenced has a bolt pattern of 8 on 6-1/2 inches so it would be close but not the same. We do not have anything that uses a bolt pattern of 8 on 170 mm.

  • Does Dexstar Steel Dual Trailer Wheel # AM20790 Require Flange Nuts
    With the Dexstar Steel Dual Trailer Wheel # AM20790 Dexstar requires the use of flange nuts in the size of 5/8"-18 like part # 95188. I can't recommend an acorn style of nut.

  • Trailer Wheels Which Fit a 5/8" Wheel Stud
    Currently the only other size wheels we have than the 17.5" # AM32NR which fits a 5/8" stud are dual wheels like the 16" # AM20790. You can consider switching to the Trailer Hub Wheel Stud # 7-223 so your axle can use a 9/16" wheel stud. You will need to verify the mounting hole size for your wheel studs to ensure this is the correct size.

  • How to Determine Needed Pilot Diameter of Steel Dual Trailer Wheel
    The pilot diameter is measured as the diameter of the large hole in the center of the wheel. The Dexstar # AM20790 steel dual trailer wheel you referenced has a 4.88 pilot diameter. So which pilot diameter would you need? To figure that out, I would recommend you measure the pilot diameter of your existing wheels, and choose replacement wheels that have the same pilot diameter.

  • What is the Correct Lug Nut to Use with a Wheel Retaining Ring on Dual Wheel Axles
    As long as your dual wheel has a flat surface where the Flange Wheel Nut # 95188 would rest against, like what the Dexstar Dual Wheel # AM20790 has, then you would use this flange wheel nut in the place of a nut with a 90 degree cone. Attached is a review video of the flange wheel nut for you to check out. In the video we pull a wheel out to demonstrate the flat surface area the nut would install on. If you are using a wheel retaining ring, like the part # 33-52-1, then you would still...

  • Dually Wheels for 235/86-16 Tires
    We currently have a dually wheel available by itself but no tire and wheel combos for duallies. Any tire shop should be able to mount the tires on the wheels for a nominal fee. For a 16 inch dually wheel we have the 16x6 inch with 8 on 6-1/2 bolt pattern with 5-1/2 inch offset # AM20783 or # AM20790.

  • American Made 16 Steel Dual Trailer Wheels
    I do have a great option for you, however the Lionshead Steel Dual Wheel - 16" x 6" - 8 on 6-1/2 - 4.75" Pilot - Silver # LHHA420 that you referenced is not made in the USA. They also do not have offset like my next suggestions. For a 16" dual steel wheel with the same 8 on 6-1/2 inch bolt pattern that's American made we have the Dexstar # AM20790 in Gray or # AM20783 for White. Both options feature a 5-1/2 inch offset, a 3,100 pound weight capacity, and come with a 2 year limited warranty....

  • 16 x 6 Dually Wheels with 4.88 Pilot Hole and 8 on 6-1/2 Bolt Pattern
    The closest we have is the Dexstar # AM20790 which has an offset of 5.5 inches. This is a 16 by 6 inch dually wheel with an 8 on 6-1/2 bolt pattern and 4.88 pilot hole; however, it is a hub pilot wheels not stud pilot. The only stud pilot wheels we carry are 17-1/2 inch wheels.

  • Replacement 16 Inch Trailer Wheel with 8 on 6-1/2 Bolt Pattern
    All of our tires and wheels are for use on trailers. If you're looking for a 16 inch, 8 on 6-1/2 bolt pattern wheel for a trailer the part # AM20790 that you referenced is just that. This specific wheel is for a dual-wheel setup and has a 4.88 inch pilot hole. If you're looking for a similar trailer wheel that isn't for dual wheels then # TTW660865WS4 is a better option. It's also an 8 on 6-1/2, 16 inch silver steel rim with a 4.88 inch pilot hole.

  • Can Hub Centric Wheels With 4.88" Pilot Hole Fit an Axle Designed For a 4.77" Pilot Hole
    There are centric rings you can find which will allow you to mount a Wheel # AM20790 having a 4.88" pilot diameter on a axle designed for 4.77" pilot holes. You will need to locate these centric rings as they are not something we currently carry. We also have the Wheel # LHHA420 with the 4.75" pilot hole size you are looking for if you do not want to use the additional part.

  • Will Dexstar Steel Dual Trailer Wheel # AM20790 Work on a 1983 Dodge 1-Ton Dually
    I reached out the manufacturer and the Steel Dual Trailer Wheel - 16" x 6" - 8 on 6-1/2 - 4.88" Pilot - Gray # AM20790 are not recommended for truck use as they haven't been tested for that use. They said that they have seen them used in that way, but it will not be covered under the manufacturer's warranty if you choose to use them in that way.

  • Recommended 16" Dually Trailer Wheels with 8-Bolt Pattern
    The Dexstar Dual Wheel part # AM20783 for 4.75" pilot or part # AM20790 for 4.88" pilot are the only two available dually trailer wheel options we offer with 16" diameter and 8-bolt pattern. These wheels are both constructed of steel. I am not aware of any aluminum dual trailer wheels so steel will be your only option.

  • What Bolt Pattern Does Trailer Wheel # AM20790 Have
    The bolt pattern hub the trailer wheel part # AM20790 you referenced is designed to fit is 8 on 6-1/2 inch which is a very common bolt pattern for dually trailer wheels. If you have an 8 lug bolt pattern on your hubs this will fit and work well.

  • How Much Does Dexstar Steel Dual Trailer Wheel # AM20790 Weigh
    Dexstar Steel Dual Trailer Wheel # AM20790 has a shipping weight of 41 pounds and weighs close to 39 pounds or so by itself minus any packaging. So if weight is an issue I would use 40 pounds in calculations to err on the side of caution.

  • USA Made 16" Dual Trailer Wheel with 8 on 6-1/2" Bolt Pattern
    Hey Al, thanks for reaching out! The wheel that comes with the Provider ST235/80R16 Tire with Silver Vesper Dual Wheel - 8 on 6-1/2 # TA96FR is made overseas, but we have an alternative with the Dexstar Dual Wheel with 5-1/2" Offset # AM20790. This wheel isn't paired with a tire so you'll have to also get the Provider ST235/80R16 Radial Trailer Tire # TTWTRTM2358016E and have a shop mount the tire on the wheel for you. Let me know if you have any other questions!

  • Maximum PSI of Dexstar Dual Wheel AM20790
    The Dexstar Dual Wheel with 5-1/2" Offset # AM20790 does not have a maximum pressure since the wheel could handle far more than any tire that would fit. Max psi is determined by the valve stem. This wheel does not include a valve stem so you could add the # AM20906 which can handle up to 200 psi.
