Note: The overall capacity of this tire-and-wheel assembly is limited to the lowest rated component. Do not fill your tire to a pressure greater than that indicated on the tire itself or on the wheel that it is mounted to.


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"

etrailer has performed to 110% of everything I have ordered from them. I am so impressed and thankful they do what they say. I bought a hitch and wiring harness for my Acura to tow a jet ski.. possibly a questionable idea... NOPE! super fast install and everything worked exceptionally well. Then I wanted to update my trailer tires and wheels.. value, shipping speed and selection as well as delivery 110% perfect. wheel galvanizing was high quality, tires high quality and inflated properly. Didn't think I would get excited about opening my wheels and tires. Thank you to the team at etrailer. NICE WORK 211322

We ordered 3 boat trailer tires from ETrailer. Quick shipping and free shipping too! Just what we wanted. Great company to deal with. They were not in stock when we ordered. They emailed and called us to let us know. And they were still shipped QUICK! We’ll definitely order from here again 566688

My trailer needed new tires. After checking local stores Etrailer had the best price hands down. I got two tires and free shipping for under $100. I have purchased from Etrailer before and both times they were quick to get it to me and the products were exactly what l needed. I will definitely recommend them. 567258

- The product was fine. 4 stars - Just don't select the wrong shipping like I may have done. I payed $67.00 on a $85.00 order (took the product 5 days to arrive). Apparently I hit the wrong button. I reached out immediately through the online contact information when I received the order confirmation email but customer service was closed. There does not seem to be an option for the customer to delete or other wise edit an order even with in minutes of placing the order. I see this as a weakness of the site. Maybe it is my mistake but should be an edit option for a period of time after the order is placed. I had many emails with cust. Svc. they basically said - "on you". It won't break the bank but would have been nice to offer some help here. Why is this shipping even an option when it takes about as long as a $12.00 version? 396727

I had originally found a wheel/tire option on Amazon but elected to go with eTrailer b/c I was not comfortable with purchasing through a 3rd party merchant -- I have had trouble if any issue is encountered. My wheels from eTrailer showed up in a sturdy box and were ready to mount. Very satisfied with overall purchase experience. The wheels are used for my small Yacht Club trailer that holds my 2006 SeaDoo GTX. For the price, you can't go wrong. Some people have reviewed the wheels as being a bit scuffed (as in not immaculately polished). I kind of chuckled a bit when reading those. Folks - you are getting 2 wheels + tires shipped to your door for ~$100 all-in. That is an insane value. My wheels were also not perfectly polished...but I was 100% ok with that. 358939

I WILL continue to use etrailer.com for all my needs that they carry/sell. Couldn't be happier. Thanks so much. 575259

I needed tires for my 5 x 8 trailer because the old tires were cracking on the sides. I priced out several companies and one of the larger discount stores wanted nearly double.

Do you have a question about this Tires and Wheel?


  • Recommended 4.80-12 Trailer Tire for Higher Speed Driving
  • All of our 4.80-12 size trailer tires and tires-with-wheels are shown on the linked page. For higher-speed highway travel I suggest the 81-mph-rated Load Range C Tasksmaster tire # TTWSF48012C which is rated to carry 990-lbs at 90 psi. Always run your trailer tires at the full psi pressure noted on the tire sidewall. It is never appropriate to under- or over-inflate a trailer tire as doing so reduces its load capacity and increases chances for heat-related failure.

  • Best 12 Inch Galvanized Tires and Rims for Small Boat Trailer
  • A radial tire flexes more than a bias tire, giving it better ground contact, traction, stability, and tread wear. Radial tires generally run cooler than bias tires, which usually leads to a longer life for radials. I would recommend going with a radial tire if possible, but provided you heed limits such as load range and psi, a bias tire will also work. We currently offer three different tire sizes that have 12 inch diameters and galvanized 5-lug rims. You can check your current tires to...

  • Comparison of Two Kenda Tire and Wheel Combos Part # AM30670 and # AM30790
  • Both tires # AM30670 and # AM30790 are Kenda tires but there are a number of differences. For starters they're different sized tires. The # AM30670 is a 4.80-12 sized tire and # AM30790 is a larger 5.30-12 sized tire. The latter being about 3/4 of an inch wider and over an inch larger in diameter. Also, they both have a C Load Range but the larger # AM30790 has a higher weight capacity at 1,045 pounds when inflated to 80 psi. The # AM30670 is rated up to 990 pounds at 90 psi. With...

The smaller tire size 4.80-8 like item # AM10002 that you referenced will fit an 8 x 3-3/4-inch wide rim but again not a 12 x 3-inch one. You may care to check out the two linked articles on trailer tires for more information about tire and wheel compatibility.

  • Spare 4.80-12 Trailer Tire and Wheel for Utility Trailer Used as a Kayak Trailer
  • The problem that you are having is due to the trailer suspension not being compressed enough from the light load. Changing tire load ranges will not help in this case. You could change the trailer suspension but then you would have to be very careful not to overload the trailer so I do not recommend that. The other option is to put more weight on the trailer so it compresses the suspension a little more. This will help prevent the ride from being so stiff and jarring when you go over...

  • How to Determine if ST185/80D13 Trailer Tire Will Fit on Trailer With 4.80-12 Tires

Since you mentioned you have a 4.80-12 tire and wheel - like the Loadstar # # AM30670, for example - I can tell you that tire and wheel measures 20.7" in diameter and 4.9" wide while the trailer tire and wheel you asked about, the # AM3S334, measures 24.4" in...

With both products the tire's 990-lb rating becomes the overall rating for the combination. I linked...

Only this style that has 10. Other option would be the part # AM30670 which has 8 triangular shaped holes in the wheel.

  • Can Trailer Tire Size of 20.5x8-10 be Replaced with 4.80-12
  • The two sizes you mentioned have the exact same diameter of 20.5 inches. The biggest difference is that the 12 inch size you are considering of 4.80-12 is much narrower at 4.9 inches compared to 8.4. Clearance wise you'd not have any problems at all. If you have a 5 lug bolt pattern you'd need the part # AM30670 or if you have a 4 lug pattern you'd need the # AM30630.

  • Best 480.12 Boat Trailer Tire and Wheel Combo

I would go with one of the model tires listed below depending on your load range which is listed after the number (12) on your tires. Your load range is either (B or C) for this size tire. When you're ready for some new wheels, you'll need a 5 on 4-1/2 bolt pattern. The only 5 bolt pattern that is offered for this wheel size is 5 on 4-1/2.

When the inflation pressure is higher that will indicate a higher load range. The Load Range B tire should have a maximum load of 785 lbs. listed on the tire. The Load Range C should have a maximum load of 990 lbs. listed on the tire. I would recommend to have the same size and load range of tire on the same trailer axle.

  • The tire diameters are very different between the two sizes. The bigger size you have now of 4.80-12 is overall 20.5 inches tall and the older size 4.80-8 is 16.1 inches. Since that difference is split between either side of the spindle you'd have one side of the trailer sitting 2.2 inches taller than the other. In a very short-term emergency situation you could probably limp home with that but I would highly recommend matching the larger tire size for a spare with something like the...

  • What is the Max Tire Pressure for the Kenda Loadstar Tire
  • No matter what trailer tire you are using, including the Kenda Loadstar # AM30670, you need to keep the cold psi rating to the what the manufacturer recommends. When you are over or under the recommended pressure then you can cause excessive heat build-up which results in a blowout. Even if it feels like the 990 lbs at 90 psi weight capacity seems like overkill for your trailer this is the best way to maintain your trailer tires. You should be able to find the 90 psi rating somewhere...

  • Correct Inflation Pressure for Trailer 4.80-12 Trailer Tires
  • Tire size 4.80-12 is not found on vehicles, but is a common trailer tire size on smaller utility- and sport-type trailers. In trailer use you do want to inflate them to the maximum cold psi pressure noted on the tire sidewall. Trailer tires should never be under- or over-inflated since they can deliver their rated weight-carrying capacity only when inflated to their specified pressure. Incorrect inflation can lead to excessive heat which is the main cause for tire failure. All of our...

  • Thinner Replacement Trailer Tires to Replace 20.5 x 8 - 10 Sized Tires
  • Your 20.5 x 8-10 sized tires are the same as a 205/65-10 sized tire using new measuring. The rims are 6 inches wide. A replacement size that's the same 20.5 inch diameter are 4.80-12 sized tires but the weight capacity is much lower. For example the Kenda # AM30670 is rated for 990 pounds at 90 psi. Your current tires are likely rated higher. The rim is 4 inches wide. If you have the clearance to go with a larger diameter tire you may be able to use size 145/80-12 which also use...

  • Can Tire Pressure be Lowered on Motorcycle Trailer to Provide a Better Ride
  • You always want to keep your trailer tires psi set to what is recommended. If the psi is higher or lower then the tire will not perform as the manufacturer states. For instance, the Kenda # AM30670 is rated for 990 lbs at 90 psi. If we were to deflate the tires at all then the 990 lbs capacity that Kenda says the tire can handle will not be the case anymore. Underinflated tires are more prone to overheating and tire failure as well. I strongly advise against lowering the psi.

  • Availability of 4.80-12 Trailer Tire/Wheel With More Than 0.12-inches of Tread Depth
  • The Kenda 4.80-12 Bias Trailer Tire with 12-Inch White Wheel # AM30660 does have a tread depth of 0.12-inches as you have noted from a previous inquiry. We do offer two other tire/wheels in this same size, bolt pattern and load range (C) and those items are part # AM30670 and # AM30679. I went to our warehouse and measured the tread depth on both of these and found them to be 0.16-inches for the # AM30670 and 0.22-inches for the # AM30679, both measured in the center of the tread.

  • Can 4.80/4.00-8 Trailer Tires be Replaced with 4.80-12 Tires on a Trailer Without Fenders
  • Yes, you can replace your 4.80/4.00-8 tires with 4.80-12 tires and wheels such as # AM30630. This larger size will not be any wider than what you have and since the trailer doesn't have fenders the extra height will not be a factory. This tire and wheel combo has a 4 on 4 bolt pattern which is likely what your existing wheels have. But if you have a 5 on 4-1/2 bolt pattern you would need a different tire and wheel combo such as # AM30670.
