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"

Steel Spoke Trailer Wheel - 16" x 6" Rim - 8 on 6-1/2 - Galvanized Finish - AM20781

Average Customer Rating:  4.6 out of 5 stars   (402 Customer Reviews)

Corrosion-resistant, 16" steel wheel features an 8 on 6-1/2 bolt pattern and meets Department of Transportation standards.


I bought one wheel two years ago and it has been subjected to all kinds of weather and condition and has held up well. I purchased 4 additional wheels to replace rusting steel wheels on the same trailer and the new wheels seemed a little rough in that the finish looks frosted in places like paint would flash from too much air pressure. Also the weld and some spots on the wheel are rough. As long as the new wheels holds up as good as the one purchased a couple of years ago I'll be happy.


Correct product, good value, quick deli very

Just a spare. Hasnt touched the road.

Exactly as ordered at a fair price and delivered as promised


Haven't had a chance to have tires mounted yet as the rims just arrived but I do want to give praise to the customer service from James. He walked me through this selection discussing with me my options. James is very knowledgeable of all trailer products. He has been helpful about a return I had to make and available should I need to re-order.


Good product. Go delivered before scheduled date


looks like a good rim nice galvanized coating. how ever the wrong valve stems installed if you plan on using a tire that requires air pressure over 65 psi


Description talked about 3750 pound rating with a 110 psi tire and the valve supplied with the wheel is a rubber snap in valve only rated for 100 psi.


When I ordered the wheels they were out of stock but I was immediately contacted to inform me about the situation. After speaking with a representative they offered me an option of a similar product. I opted to wait for the manufacturer to send the wheels. I was very happy how they remained in contact with me and kept me updated until the product was delivered.


These rims were above my expectation. My order was shipped out quickly and arrived sooner than expected. I would recommend etrailer to anyone needing trailer parts and supplies.


Works and looks great.


The item is a perfect match for the wheels on my trailer. I'm mounting a spare for my tri-axle boat trailer.


Great quality and never have to worry about rusty wheels again.


We have 12 2500 HD. We pull a lot of heavyweight tr. Rvery day . There tuff. Never a problem.


Looks like the original only a lot less road weary.

Shipped when they said it would ship, arrived when they said it would arrive.

Very easy to work with.


Great galvanizing on the rims. Fast shipping


Fast shipping and great quality.



Excellent product




Packed well.


Review from a similar Galvanized Spoke in Trailer Tires and Wheels

If I could put negative stars I would go negative 100+
I'll explain bought these rims because I pull trailer in winter and wagon wheels don't last figured galvanized would after installing towed 12 miles came home retorqued as recommended pulled 150 miles retorqued again (with impact) pulled about 200 miles and tire flew off in 4 lane rush hour traffic, found all lug nuts loose on remaining tires it broke off all 5 studs bent fender ground u bolts on axle almost off trying to get to side of road, couldn't find the tire it went into traffic how everybody missed it who knows while I was dealing with tow truck someone must have stopped and took it.$300 tow bill later put a couple of studs in so I could put spare on and get into shop the pictures are the damage the lug nuts didn't seem to fit in hole right two off the tires weren't loose by feel wiggling the tire while jacked up but the nuts were working regardless, looking at back of rim the holes are offset and don't sit flush on hub if you look at the one pic you can see my spare sits flush as did the other rims I replaced with these pos's. Basically the rim is relying in the bolt hole and surrounding steel to support the weight of trailer never going to happen maybe if your trailer is empty, bolted on there is a 1/8th inch space between the hub and lug nut JUNK DO NOT BUY I will have a grand into fixing what these rims did. as a note I have pulled trailer's for 40+ years I own 6 other trailers of various styles have never had a tire come loose much less 4 of them. I have bought other items with no problems

I reached out to the manufacturer in regard to the performance of the rims. I found that you would want to use a torque wrench versus an impact wrench, preferably one that clicks, otherwise the possibility of over-torque on the lugs is very real, as in this situation. If an impact wrench is the only option, it should be set to the lowest setting and used with extreme caution.

Review from a similar Galvanized Spoke in Trailer Tires and Wheels

Wheel has lumpy galvanized coating. Took to Costco to have tire installed and they couldn't install tire because of lumps in the bead area and would not warranty tire if it failed. Called customer service at etrailer and was on hold for 15 minutes and they wanted me to send pictures. They said they are backed up 3-5 days for RMA and out of new stock. I ordered replacement from [online]...

I will have our Customer Service team reach out to you.

Review from a similar Galvanized Spoke in Trailer Tires and Wheels

The finish on this wheel was pretty rough. It appeared to have curb rash on the circumference and there were paint flakes in the lug nut/ valve stem holes. It’s hard to tell if this was a brand new wheel with a horrible paint job that also dripped down all on one side or if it was welded and refurbished and then sold as new. The tire mounted OK, with no apparent leaks so far. I guess it will be OK for my Harbor Freight light utility trailer, unless it starts leaking or it comes apart some how.

During the galvanization process the wheels are dipped into the solution and then are drip dried. Which means that it can allow for a rougher finish, and is probably why it is is looking dripped more on one side than the other.

These are a great product. The quality of the galvanization is better than I expected. These will work well for my application.
