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"

Quick shipping from etrailer, but I wish I had noticed that these don't come with valve stems before I ordered. I got the high-pressure stems from them soon enough though. Like others have said about these, they look shinier in the pics then they really are. Some of the welds were a bit rough, and the finish wasn't perfect, but a liberal amount of elbow grease got them looking great. Huge improvement from the ugly old wheels I had. So far I'm happy. We'll see how they look after some use. 453212

FAST DELIVERY: I ordered online late Sunday afternoon; these were delivered to my porch in West Texas on Wednesday. (I've ordered from eTrailer a few times over the years; same good experience each time.) I had tried painting my old white wheels; the paint did not stick well, so I threw up my hands and ordered these, which I had previously considered. APPEARANCE: Now, these are not chrome; they are galvanized and therefore have every right to look like your grandmother's galvanized wash tub. But these (I ordered three) look very much like the photo, which to me appears to be a semi-gloss, slightly uneven chromed look. So these wheels do, at casual glance, appear to have been chrome plated; on closer inspection, the galvanized irregularity is visible, a mildly waxy sheen or such. My white painted wheels lasted 20+ years, then became a bit rusty; I expect these to last much longer. 679259

Ask the Experts about this Americana Tires and Wheels

Do you have a question about this Tires and Wheel?


  • Upgrading Trailer Tires and Wheels For Highway use on Harbor Freight 4x8 Folding Trailer
  • From my research on the Harbor Freight 4x8 folding trailer uses 4.80-12 tires on a 12 inch wheel for the 1195 lb capacity trailer and a 5.30-12 for the 1720 lbs capacity trailer. It is a good idea to check your existing tires to see which size they are. I recommend Taskmaster 5.30R12 part # TT53012C If your existing tires on the trailer are 5.30-12. If your existing tires are 4.80-12 I recommend Taskmaster part # TT48012C. Both of these tires are radial tires which are designed...

  • Are Trailer Wheel Hub Bore (Pilot Diameter) Measurements Universal Sizes
  • The center hub bore size can vary between wheels so you will need to verify the hub bore size (pilot diameter) before replacing your 8" wheels with 12" wheels. For example, the Steel Spoke Trailer Wheel # AM20124 with the galvanized finish has the 4 on 4" bolt pattern that it looks like you have and a pilot diameter of 2.84". It looks like your current lug nuts sit flush against your wheel and they don't have a cone shape. If this is the case then you will need 60 degree coned lug nuts...

  • Trailer Wheel and Tire Options for Size 5.30-12 on 4 Lug Trailer Wheel
  • Based on the numbers you listed what you have is a trailer tire size 5.30-12 Load Range C on a 12 inch trailer wheel with a 4 on 4 inch bolt pattern. For a combo that covers all of that aside from being a radial we have the # AM30780 for a white wheel or part # AM30790 for a galvanized wheel. None of the combos we offer in this setup have a radial option For just the tire we have the part # TT53012C which will work well and is a radial. Then for a wheel to match this we have the part...

  • Availability of a ST145/R12 Trailer Tire and Galvanized Wheel Combo
  • We offer many wheel/tire combos in size ST145/R12, see link, but none on a galvanized wheel. Of the wheel/tire combos that we offer the part # AM31208 is compatible with the bolt pattern specified on the Dexstar Steel Spoke Trailer Wheel, part # AM20124 you mentioned. The tire and wheel combos we receive are already mounted on rims from the manufacturer. Currently we do not have a machine to mount the tires to rims when these parts are purchased individually. If you buy the Kenda Karrier...

  • Valve Stem Mount Hole Diameter for the Steel Spoke Trailer Wheel # AM20124
  • I went out to the warehouse and found that the hole for the valve stem on the Steel Spoke Trailer Wheel # AM20124 measured about 0.45" in diameter. We actually have the Americana Metal, Bolt-In Valve Stem # AM20906 which will fit perfectly with this wheel an can handle psi ratings over 100 so you never have to worry about the psi rating of your valve stem.

  • Recommended Replacement for ST145/R12 Trailer Tires
  • Trailer tires are designed to fit on certain wheels so if you have ST145/R12 trailer tires now, you do need to replace your tires with the same size or they won't fit. I recommend the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range D # AM10130 (1,220 lb capacity) or Load Range E # AM10140 (1,520 lb capacity) which will fit 12" x 4" wheels like Taskmaster Steel Modular Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - Silver # TTW240545SM1 or Steel Spoke Trailer Wheel - 12"...

  • Torque Specification for 12 Inch Wheel with 4 Lug Nuts on Boat Trailer
  • I have attached a chart for you to take a look at that includes the lug nut torque specifications. If your wheel uses 1/2 inch lug nuts or wheel bolts like the 12 Inch Steel Spoke Trailer Wheel # AM20124 referenced in your question, you will torque them to 75-85 foot pounds. If you have different size lug nuts, then you will just follow the specifications included in the chart for that size on a 12 inch wheel.

  • Correct Lug Nut Torque for 12-Inch Steel Trailer Wheel
  • For a 4-lug steel wheel with 1/2-inch studs like # AM20124 the correct torque range is 75-85 ft-lbs. For a 15-inch steel wheel like the item # TTW550555WS1 that you referenced the torque range is 90-120 ft-lbs. In general the larger a wheel is the more torque it requires and steel wheels typically need higher torque than aluminum wheels.

  • 12 Inch Radial Trailer Tire and Steel Wheel with 4 on 4 Bolt Pattern for 2005 Jayco Tent Camper
  • I have a solution for you, but none of our 12 inch radial tires that are pre-mounted are available on a steel wheel with a 4 on 4 inch wheel bolt pattern. We do have steel 12 inch wheels with 4 on 4 inch wheel bolt pattern available, but the are not offered with a tire already mounted. The best solution will be to get the tire and the wheel and then have a local tire shop mount them for you. For a 12 inch radial trailer tire, we offer the Kenda Karrier S-Trailer ST145/R12 Radial Trailer...

  • 12 Inch Wheel Recommendation For Trailer
  • The galvanizing process on the wheels we offer like part # AM20124, do have a shinier finish. For a more dull traditional finish as you mentioned I recommend the Americana Aluminum Split Spoke Trailer Wheel, part # AM22318HWT. This wheel has a 4 on 4 bolt pattern and is a 12 by 4 inch rim. Also, it has a capacity of 1,220 lbs at 80 psi.

  • Replacement High-Speed Tires for 4.80-12 Tires on Boat Trailer
  • The term "high-speed" tires on the sidewall really isn't a good indicator of the speed rating for your current tires because manufacturers have been changing (increasing) the safe speed for tires in the recent past. So if your tires are old enough then they could be rated for 65 mph which used to be known as fast. Since you are looking to replace your current tires and you are looking into options that are rated for higher speeds I recommend using the Taskmaster 4.80-12 Bias Trailer...
