Bias Tires vs. Radial Tires

Bias vs. radial tire graphic

Bias ply tires are designed for off-road or agricultural applications. They are built with thick, durable nylon cords that are positioned at a 30- to 45-degree angle to the direction of travel. The layers alternate in a crisscross pattern, making the sidewalls stiffer so that the entire tire is able to flex easily. As a result, the tire provides a smooth ride and improved handling when trailering on uneven surfaces.


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"

Great price and fast delivery. Bought for boat trailer. Better bargain and more convenient to buy mounted than buying tire alone and having it mounted. Bought another pair for second trailer 655566

My boat trailer needed new tires. I called etrailer and spoke to pat c. She was very nice and helpful. The tires/wheels i originally was going to order were out of stock and i needed them like yesterday. Pat c recommended another product which was in stock and ready to ship. I accepted her recommendation and purchased them. Prices were good and shipping was fast. Tires/wheels look great on the trailer. 552412

The tire/wheel combination took a bit longer to deliver as it was out of stock temporarily but still arrived within 2-3 weeks of ordering. The tire/wheel shipped in a nice sturdy box, and upon opening was in perfect condition. The first thing I look for is the manufacture date of the tire, which showed it was produced about 6 months earlier which is pretty good, since all tires start to deteriorate from the day they are produced. This will be a spare for my EZ Loader 1,000# trailer and should work out great. As always the price and service at etrailer was terrific and included free shipping, so that's a big plus. 234152

Never ordered tires before but had to replace the dry-rotting existing tires on the trailer I had inherited from my dad's estate. A friend told me about this website and how great it was, so I thought I would visit it to check it out for myself. This website was VERY helpful and informative about the ins and outs of tires, rims, and critical measurements. I was also stepping up from 8" tires to 12" tires and was unsure about whether or not the new rims would fit on my existing hubs. The hole dimensions they provided led me to believe I could order new galvanized rims with the new tires and have a reasonable expectation for a good fit. So I ordered them, and even though we were in the midst of the corona virus lock-down, the tires arrived in sturdy boxes 3 or 4 days later. I cleaned the existing hubs and studs on the trailer, and slipped the new tires on without a hitch. Every one of them fit like a glove! Very happy with this company and will be visiting them for more accessories and such - strongly recommend them to all my friends and to any one looking for a company with excellent product choices, great pricing, sturdy shipping packaging and quick delivery! 802840


Comments
I am so glad to hear the tires worked out great for you! When mounting a tire with a fender, keep in mind that you usually want about 4 inches between the tire and the fender. This allows for maximum suspension travel so that your tire will not rub on the inside of the fender.

Ask the Experts about this Kenda Trailer Tires and Wheels

  • Max Highway Speed Rating for 4.80-12 Tires
    The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 5 on 4-1/2 - Load Range B # AM30590 have a max speed of 65 mph. When trailer tires are not speed rated with a letter, the default is 65 mph max. I've attached an article to assist. If you want a speed rating higher, then for that tire size I recommend the Taskmaster 4.80R12 Radial Trailer Tire w/ 12" Silver Mod Wheel - 5 on 4-1/2 - Load Range C # AT12R45SM or # AT12R45WS. These are rated for speeds up to 81 mph. If...

  • Do Trailer Tire and Wheel Combinations Come Balanced From the Factory?
    Because tire/wheel combos like the Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30590 are assembled by the manufacturer, they do come with a certain amount of balancing already done when they are matched up; the high spot of the wheel is usually matched with the low spot on the tire. Since we do not have the ability to balance tires in our warehouse, we rely on them to complete this task. Since trailer tires are meant to handle a vertical load more-so than they are relied...

  • 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...

  • Does Load Range B Trailer Tire Size 4.80-12 Have Capacity for 500 lb Trailer
    Wheel and tire combos that are 4.80-12 Load Range B mounted on a 5 lug wheel like the part # AM30590 have a weight capacity of 785 lb per whee/tire. That means that with two of them you'd easily have more than enough capacity for your 500 lb trailer.

    The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 5 on 4-1/2 - Load Range B # AM30590 matches all of your criteria and is my recommendation for you. For your spare carrier, I recommend the Extra Offset Trailer Spare Tire Carrier by Dutton-Lainson # DL22145 or the Fulton Hi-Mount Spare Tire Carrier - Fits 4-, 5-, and 6-Lug Wheels # FHDSTC0101 depending on your style preference. I've attached a video of each to assist.

  • Can You Mix Different Load Range Tires On The Same Boat Trailer Axle
    The 4.80X12 2 ply tire at 60 psi that you have is a Load Range B tire. The other 4 ply tire at 90 psi should be a Load Range C tire. 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. You will want to have the correct...

  • Replacement Trailer Tire for a Trailer with 6K Axles and 235/85R16 Tires
    First lets look at the wobbly tire. If it is indeed a damaged wheel then you will want to replace that as soon as possible. If you notice any odd tread wear like just the inside, just the outside, or flat spots in the middle, that can indicate a problem with the spindle, the hub, or the axle. If the axles have been flipped (turned upside down) then you will notice tire wear on the inside tread. The axles will need to be turned the right way if they are flipped because that greatly diminishes...

  • Weight of Kenda 4.80-12 Trailer Tire with 12" Galvanized Wheel # AM30590
    The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30590 that you referenced has a total weight of just about 18 pounds. The Kenda tire by itself weighs 8 pounds and the galvanized steel wheel is 10 pounds.

  • What PSI Should be Ran in Trailer Tires that Have Different Load Ranges
    For trailer tires you want to always use the max pressure that is listed on the sidewall of each tire. Doing so ensures that you get the max capacity for the tire. Now ideally you wouldn't be running two different Load Ranges on your trailer since that means you would run different PSIs in each tire. But still you would want to run the max PSI in each until you can get all of the tires matched.

  • Are Trailer Tires Rated Individually or as Pairs
    The Load Ranges and weight capacities that you see on our trailer tires are the rating per tire. So you would need to double that for the overall axle capacity. For example, the tire capacity of the part # AM30590 that you referenced is 785 lbs so when using two you would have a capacity of 1,570. You should note that the wheel on this is rated higher at 1,250 lbs. But you would be limited to the tire capacity since that is the lower figure. I also attached a link to a review video...

  • Spare Wheel and Tire Recommendation for Karavan KBE 1250-46
    The part # AM30590 would be a great spare wheel and tire replacement as long as you have a 5 on 4-1/2 inch bolt pattern like what this has. Otherwise if you had a 4 bolt pattern you'd want the part # AM30630.

  • Maximum Load Capacity of Kenda 4.80-12 Bias Trailer Tire
    The Kenda 4.80-12 Bias Trailer Tire and 12 Inch Galvanized Wheel Combo # AM30590 offers a maximum load capacity of 785 pounds when the tire is inflated to 60 psi. This means that a single tire can support up to 785 pound when properly inflated. If your trailer is a single axle trailer, two of the # AM30590 tire and wheel combos will offer a maximum load capacity of 1,570 pounds for the trailer. If it is a dual axle trailer, 4 of these wheels will offer 3,140 pounds of maximum load capacity....

    The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 5 on 4-1/2 - Load Range B # AM30590 is a similar tire and has a max rating of 60 psi. I can't confirm that your tires will be the same without the rating listed on the sidewall. You may want to consider changing the tires because they are old and do not have the max psi rating listed on the sidewall. If there is no speed rating listed, you also will need to consider 65 mph your max speed. I've attached an article to assist....

  • Can Trailer Use Different Brand Tires if Size, Load Range, and Construction Is Same
    Yes, you can use a different brand of trailer tire as long as everything you mentioned matches. Size (this is the most important to match obviously), construction (bias vs radial), Load Range, and tire pressure. You didn't mention what tire size you have but I attached a link to a page that has all of the trailer tires we offer. You can select the size you need from the filters and then from there the other options to see what would fit and work well.

  • What Is The Right Spare Tire For My CE Smith Multi Sport Plus Boat and Kayak Trailer w/ Bunks?
    Kenda makes a galvanized wheel # AM30590 that matches the specs of your trailer's wheels and tires. There is a white option available as well # AM30580. Both are the right wheel and tire.

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...

  • 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...

    It is recommended that tires always be inflated to the max psi, which should be listed on the sidewall of the tire. The psi ratings for two tires of the same size will differ based on each tire's load range. For instance, a Kenda 4.80-12 tire, such as Item # AM30670, is a load range C tire with a capacity of 990 lbs at 90 psi. However, the same size tire at load range B, such as Item # AM30590, has a capacity of 785 lbs at 60 psi. Different tire manufacturers may also have different psi...
