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"

Painless and easy transaction. Wheel arrived today and it's exactly what I needed!

Tires are performing well. Been on 6 or 8, 400 mile trips to NC and SC coast. So far so good .

Product arrived and is exactly as pictured on website. Shipping container (for 2 fenders and 2 wheels w/tires) was the strongest I have seen in some time. Fenders were sturdy and fit perfectly. Wold highly recommend etrailer to my friends.

Only used the trailer once since installing new wheels and tires. Smooth ride, no problems.

Excellent quality and fast delivery.

After shopping around locally for new tires for my boat trailer I checked in with etrailer and found the tires I needed with galvanized rims for less than just a tire. I took advantage of their free shipping minimum and purchased a spare tire mount and trailer hitch for another project I've been working on. Expecting a reasonable 5 to 7 day arrival I was surprised when my items arrived in only 2 days. The package tracking feature on the web site was spot on and the follow up emails from Team etrailer made this a great shopping experience. All my items were packaged in one container and in brand new off the shelf condition. BTW, the tire and rim choices were so numerous there is no doubt you'll find exactly what you are looking for. Thanks again to the team at etrailer. See you soon.

Thanks for my new tires Just in time for the weekend

I originally talked to Katie who was of great help in determining the appropriate bearing sizes. This was an older trailer axel and it took a lot of searching and research . She made careful notes of our findings,and put them in the contact log . Both of these ladies really know their bearings,and created a package of repair parts... I ordered a set of tires too,and it was delivered to Northern Mi in 1.5 days Roger Zap PhD

- AM30750

Outstanding Service and quality products! Ordered and had two boat tires in less than three days. The tires and wheels were well depicted on the web-page. Description was very accurate as well. I would recommend etrailer!!!!

- AM30750

Exactly what I needed. Had a fishing trip planned and found my tire flat. No one local carried the tire. Since the old wheels were in pretty bad shape, I decided to get both new tires and wheels. I had them the next morning and the fishing trip went smoothly.

- AM30750

Timely delivery and a good product. Price wasn't too bad.

- AM30750

Great site to buy from. Fast service and delivery. Product as described. Would buy again from this site.

- AM30750

After a year of use and probably 5-6,000 miles these tires and rims are still working great! They are on a jet ski trailer that weighs around 700lbs and saw 95% 80mph highway. The other 5 percent is all in the water at boat launches and in the sand/salt water at the ocean. The galvanised coating still looks like new! Next time I need tires these will be what I buy!

- AM30750

I am very happy with this tire/wheel setup. I run this trailer hard and the roads here are terrible. I will definitely buy theses again.

- AM30750

Good service. On time

    The Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30750 that you referenced has a maximum speed of 65 mph. If you want a tire and wheel combo with a higher rating we do have the Taskmaster 5.30R12 Radial Tire w/ 12" Silver Mod Wheel # AT53012R45SM which has an excellent speed rating of 81 mph. It also features a maximum load of 1,050 pounds at 80 psi. I have attached a couple short video reviews on these tires that you can check out as well.

  • Can a 4.80-12 Tire Be Upgraded to a Larger and Higher Capacity Tire
    There's no reason you couldn't upgrade your 4.80-12 Load Range B tires with Load Range C's like the part # AM10062. These would fit the exact same as your current tire with the only difference being that they have a higher Load Range. You could also go with a 5.30-12 like the part # AM10068 as long as you have room for a tire that is just a tiny bit taller and wider. This tire is 5.5 inches wide and 21.9 inches tall, whereas the 4.8-12s are 4.9 inches wide and 20.7 inches tall.

  • Can Pressure be Lowered on Trailer Tires
    When a trailer tire is wearing more down the center of the tread, this does indicate that the tire is over-inflated. Trailer tires should always be inflated to the max psi as listed on the tire's side wall. You should only lower the pressure on your tires if they were inflated past the max psi in order to get them down to the recommended number. Otherwise, I do not recommend lowering the pressure on your tires to below their recommended max psi. This is because the load capacity of...

  • When Is It Necessary To Match The Correct Pilot Hole Size For Replacement Trailer Wheel
    The only time you have to match up the pilot hole is when your hub uses lug bolts, which then would use a hub-centric wheel. As long as your trailer hub uses lug nuts, the pilot hole will not effect mounting your wheel to the trailer hub because the lugs will center the wheel on the hub. You will need to measure the bolt pattern of your trailer to determine the correct wheel you will need for your trailer (see FAQ). You will also want to choose a wheel with a larger pilot hole size than...

  • 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...

  • Recommended Tires To Traverse Sand with Triton Trailer
    The Kenda ST145R12 Radial Trailer Tire w/12" Aluminum HWT S5 Black Wheel - 5 on 4-1/2 - LR D # AM31206HWTB you asked this question from are great tires for travel on roads and highways. Trailer tires are built for stiff sidewall and to be run at the max psi which makes crossing sand anything but ideal. The best option is to get a second set of tires with a low load capacity rating like # AM30750 so the sidewall isn't as strong and then let the psi of your tire run as low as possible...

  • Recommended Galvanized Wheel and Tire Combination with 5 on 4-1/2 Bolt Pattern for a PWC Trailer
    You will want to select your tire and wheel combination based on the gross weight capacity of your PWC trailer axle. This rating should be listed on the trailer tongue as GAWR. With that number you would select a tire and wheel that has a capacity rating of roughly 1/2 of the GAWR. Selecting a combination that is rated slightly higher than the axle would be better than selecting one that is lower in capacity.

  • Recommendations for ATV Search & Rescue Carrier
    We unfortunately don't carry hubs compatible with the 4/110 bolt pattern as that is not standard for any trailers. My recommendation is to use the Timbren Heavy-Duty Axle-Less Trailer Suspension - Straight Spindle - Wide Tires - 1,200 lbs # ASR1200S03. This will give you the independent suspension and allow you to dictate the width of the unit for your precise desires versus having a standard axle length. This does require a 2 inch square bar unless there is a cross brace in the location...
