Note: These 4.80/4.00-8 tires fit in the same space as a 4.80-8 size tire, but are not an exact match. On a trailer with 4.80-8 tires, we recommend either replacing all tires/wheels with 4.80/4.00-8 tires, or replacing one or more with 4.80-8 tires.

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"

Video Transcript for Kenda Tires and Wheels AM30040 Review

Today we're going to review part number AM30040. This is the Kenda 4.80/4.00-8" Bias Trailer Tire mounted on an 8" Dexstar white spoke wheel. We'll start with the rim dimensions. This is an 8" diameter wheel, so if we measure inside-to-inside it would be 8". Width of this wheel is 3-3/4". The bolt pattern on this wheel is 4 lug 4" bolt pattern.

Best way to measure that would be from the center of one bolt hole to the bolt hole directly opposite of it. Center to center would be 4", so that'll be a 4 on 4" bolt pattern. The wheel capacity is 910 pounds. This wheel does use a real bolt size of 1/2"-20. Another critical dimension is the center of all called the pilot hole diameter.

This is what will fit over the hub on your trailer. If you measure the diameter, it would be 2.5". This wheel has a white powder coat finish. Now, we'll move on the tire. The tire is a Loadstar size 480/4.00-8".

This is load range C tire, which is a 6 ply rated tire, has a maximum weight capacity of 745 pounds at 90 psi. This tire is of the Bias construction, which would mean the cords on the inside of the tire will run the length of the tire. One last measurement we are going to do is the overall diameter. If we measure that would be16". This tire/wheel combo is warranteed as a limited 2-year warranty.

And that should do it for part number AM30040.

So far excellent..last tires lasted 15,000 mi. on Mini-Mate motorcycle camper over rough roads. These are going to Alaska and in load range C for gravel and bumps. Wheels have perfect paint and the 3 raised dots in rim recess to hold my new baby moon hubcaps. Popped them on new wheels/tires today and they fit over bearing buddies and seated more firmly and tightly with than I've experienced before with no rattle at all. The tires installed more easily because the center hole was smaller than many old sets of wheels and lug bolts aligned easily and exactly. The Kenda 6-ply have been good in past but was very pleased with last tires(CST) the rubber stayed soft and didn't crack. My spare is also Kenda 6-ply and hasn't shown cracks through 4 sets of tires on the trailer. The new ones look to be of same high quality. They arrived quickly and was able to install between work commitments. After trying to order same on other sites for over a week and get info as to plies/wheel type, etc., I stumbled on eTrailer site and 'bingo' all taken care of and perfectly! 181752

I normally don't reply to outfits that I purchase products from. however after dealing with "etrailer" I feel compelled to leave a review of their products and service...I am rebuilding an old motorcycle trailer and I recently purchased a set of trailer wheels w/ tires and bearing sets from them.... the products arrived w/in 3 days and were very reasonably priced... the great thing about them is.. I ordered the parts over the internet on Sunday afternoon, I didn't expect to hear from them until possibly Monday or Tuesday, I checked my messages SUNDAY evening and I had already received TWO reply's from etrailer folks.. one confirming that they had received the order and another one saying the parts had shipped.. also that they had changed my shipping to a priority shipment with no additional charge...... I received the parts on Wednesday morning....... the wheels and bearings were as they had advertised and were well packaged... They have an outstanding package tracking system (better then UPS's)... I highly recommend etrailer for trailer parts and will always use them when I need something they carry..... this is my second purchase from them and couldn't be more pleased... thanks guys.+++++ 92648

Great quality at a very good price, tires run smooth and quiet down the road. 97820


The tires and wheels are holding up excellent. I have put about 1200 miles on them, usually loaded with about 800lbs. Tires are showing very little wear and wheels have no rust.

Tires fit as expected, and appeared to be high quality. I bought my trailer off craigslist and the tires had massive cracks in the rubber, the previous owner put tire tubes in the tubeless tire. I tried to inflate the tube but it only inflates to 30PSI. I was very concerned that the rated loading of the tire would be compromised and didn't want to be "That guy" on the side of the highway. Bought these due to their load C rating which puts my mind at ease when hauling. Most brick and mortar stores only sold this size up to a load B range. 231516

The wheel & tire were an exact fit of the old wheels. The powder coat will last many years. The wiring harness in the picture was also from It simply just plugged it in (I loved that part). That's so much easier than hard wiring a harness to a vehicle. 106097

I have just mounted the wheels and tires I purchased for my motorcycle trailer. Since I have not yet put any miles on them, I cannot rate the wear characteristics. This is the reason for the middle of the road rating from me. The transaction with etrailer was very smooth and their prices are good and the rims and tires look like they are of good quality. 56030

Had checked at several other places and had the best price for these tires, one place had them priced at $15.00 each above the etrailer price. I couldn't believe the tires arrived when they did. Ordered on Wed and received on Friday. Will order from again 161542

Ask the Experts about this Kenda Tires and Wheels
Do you have a question about this Tires and Wheel?

  • What is the Highest Rated 4.80-8 Trailer Tire or Tire and Wheel Combo Available
  • For a 4.8-8 trailer tire with the most weight carrying capacity, we have # AM10004. This is a tire by itself and it is rated for 760 pounds at 90 psi. It fits 8 x 3-3/4 inch wheels. The highest rated tire and wheel combo in this size with a 4 on 4 bolt pattern is # AM30040, also at 760 pounds at 90 psi. The highest rated tire and wheel combo with a 5 on 4-1/2 bolt pattern is # AM30060 at 760 at 90 psi also. I have included a link to our tire and wheel FAQ articles for you.

  • Which 4.80 X 8 Size Tires Can Be Used On A Minuteman Trailer To Maximize Tire Tread Life
  • The 4.80x8 tire size has a overall diameter of 16.1 inches and a section width of 4.6 inches. I would not recommend going to the 5.70x8 size or the 215/60-8 size, because you would be increasing the overall diameter to 18.1 inches, which is 2 inches taller. When you go to a taller tire you are making the trailer taller and that will increase the chance of more sway, as well as possibly causing clearance issues. I would recommend going with the Kenda 4.80/4.00-8 Bias Trailer Tire...

  • Is The Kenda 4.80/4.00-8 Bias Trailer Tire with 8 Inch White Wheel, # AM30040, Rated For The Highway
  • The Kenda 4.80/4.00-8 Bias Trailer Tire with 8 Inch White Wheel, # AM30040, is highway rated. Trailer tires have a speed rating of 65 mph. Trailer tires are designed for carrying a maximum load at all times, so to do that they are reinforced in the sidewall. With the sidewall being reinforced, that causes the heat to build up more quickly at lower speeds with a load on the tires, so you will not want to run a trailer tire at higher speeds than the 65 mph speed limit.

  • Kenda 4.80/4.00-8 Bias Trailer Tire/ Wheel Combo As Replacement for Existing 4.00-8 Tire
  • The 4.00-8 tire is an obsolete size that is no longer manufactured. The name 4.80/4.00-8 is used so people will know that the new size which has a tread width of approximately 4.8 inches is the correct replacement that would be slightly wider than your existing tire. The # AM30040 tire/rim combo you referenced would be an acceptable replacement for your existing tires, as long as they are replaced in pairs. The 4.80/4.00-8 tire is designed for a 3-3/4 inch wide rim and is 16.1 inches in...

  • Comparing 4.80/4.00-8 Trailer Tires and Speed Rating of 4.80/4.00-8 Trailer Tires
  • Tire and wheel combo # AM30040 is the same tire as # AM10004. They are both made by the same company and both have the same rating and load range. The trailer tires that we carry are rated for 65 miles per hour. You do not want to exceed the speed rating because it will build up excess heat. Trailer tires already have a thicker sidewall than passenger vehicle tires and this adds to the heat they generate. So you do not want to increase the heat by going over 65 miles per hour. I have...

  • Is Tire on Americana Tires and Wheels, # AM30040, Tube or Tubeless

  • Is the Kenda Wheel and Tire # AM30040 Rated Per Wheel or by Axle
  • The tire and wheel capacity for the Kenda 4.80/4.00-8 Bias Trailer Tire with 8 inch White Wheel # AM30040 that you referenced is rated for the individual tire and wheel, not per axle (2 wheels and tires). You should note that the wheel capacity is 910 lbs and the tire capacity 745 lbs at 90 psi. This means a couple things. First, your towing setup is always limited to the lowest rated component in the setup, so in this situation the tire is rated lower than the wheel so the overall capacity...

  • You can check out the attached helpful article that explains how to determine the bolt pattern. You may find that the bolt pattern on your trailer is actually 4 on 4. I have attached a photo of a 4 bolt wheel we offer that shows where you measure. If you find you have a 4 on 4 bolt pattern, one of the 8 inch tire/wheel combinations I recommend is part # AM30000. this is a Load Range B, 4-ply tire that has a maximum load rating of 590 lbs at 60 lbs.

  • Can a Load Range C Tire be Used Instead of a Load Range B Tire on a Trailer
  • First, make sure that you stay within the gross trailer weight capacity for your trailer. If that 200 pounds extra puts you over the gross trailer weight capacity then you will want to carry that extra weight in the vehicle. Going with a higher capacity tire will not increase the gross trailer weight capacity. With that said since you have a long way to go and such small tires, having a stronger tire in the same size would help to reduce the chance of anything happening to the tires....

  • Availability of Trailer Tires for Tilt Trailer
  • I would need to know what size rims and tire you have on your tilt trailer to be able to pick out the correct replacement rim and tire to match what you have. If you can get the size listed on the side and then check out the link I attached that has all of the tires and rims we have, select your tire and rim size from the left facets, then select radial, and then select your wheel bolt pattern and you will have the correct rims and tires listed.

  • Lug Nut Torque Rating Recommendation for Tightening the Kenda Wheel and Tire # AM30040
  • Depends on the stud diameter, if you install the part # AM30040 on a 1/2 axle stud you would want to use 80 ft lbs of torque. If on a 9/16 inch stud you would want to use about 140 ft lbs of torque.
