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"

This wheel was an amazing find! A perfect match for the OEM wheel on my 2006 Fleetwood Evolution. The price was great and it was delivered in 5 days free. Thanks for the great communication throughout. Etrailer.com is my top source for all things trailer and towing. 877981

Great service and knowledgeable staff! 797869

I like these new rims / wheels. They look sleek, clean, simple and mean business. Nice shine. I chose them because they looked solid, with wide 5 spoke design. Trailer tires blow out and the rim slams the pavement. Hoping this wont happen. That is why I also bought spanking new Goodyear Endurance tires, made in the USA, higher load rating. Cheap China tires blew out. I also bought chrome lug nuts and center hub cap to complete the look. No point in a half arsed upgrade. Center hub cap can access bearing buddies. These rims are made in China and I hope they meet my expectations. 711933

We found a cracked wheel on the 5th wheel camper and needed a new aluminum wheel. We called Etrailer and spoke with Dylan who walked us through all of the dimensions we needed to collect from the old wheel to order a new wheel and provided us with the wheels available from the etrailer inventory. GREAT SERVICE that was fast and friendly and what a good match. Thank You. 515051

It held up to a 2,500 miles of abuse holding up the 5th wheel. We broke a spring and that locked these two tires together. The new wheel is fine but we now have 4 new springs, two new equalizers and a wet bolt kit.

Best experience ever. Order was shipped quickly, wheels arrived double boxed, in mint condition. Excellent product quality. Upgraded to D load range 15's, hoping they do a little better on the long highway trips to the many lakes here in the PacNW. 297196

Rims look fantastic. Customer service was even better. One of the parts I needed was backordered. They called right away and were flexible enough to allow an exchange and arranged quick shipping. I was a little apprehensive about shipping aluminum rims but the packaging was outstanding and everything arrived in good shape. Would definitely recommend etrailer. 190056

Is this rim offset zero 0?
-- comment by: Robert - 04/24/2013


The offset on most trailer wheels is 0. We only note offset in our product descriptions if it is not 0.

The wheel looks better in person than on the website, but the presentation on the website is excellent. The brushed aluminum gives the wheel a stylish look, and it really gives the trailer a finished look with new tires & lugnuts. I definately would highly recommend this wheel. One hint - make sure whoever mounts the tires is very careful not to scratch the wheel, and uses weights adhered to the inside of the wheel not to scratch the outside also. 11918
