Radial Tires vs. Bias Tires

Radial tire vs bias tire graphic

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.


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 Complete Breakdown of the Triangle ST235/80R16 Heavy-Duty Radial Tire w/ 16" Steel Dual Wheel

Hi, everybody. Andy here with etrailer.com. Let's take a look together at this Triangle ST235/80R16 Load Range G Heavy Duty Radial Tire with the 16 inch black steel dual wheel. This special trailer tire, or ST tire, has sturdy sidewall so that it can handle heavy loads. It is created specifically for trailers, and it's not intended for use on other vehicles. As you know, radial ply tires are designed for trailers that are towed on the highway.

This radial tire is constructed with all steel belts to enhance the durability and extend the tread life. The computer generated tread design and premium rubber compound materials are gonna give you superior traction in wet or dry conditions. Now as I mentioned at the beginning of our time together and as we have stamped here on our tire, this is an ST235/80R16 tire. The section width is 9.25 inches. The outer diameter is 30 and seven eight inches.

This is a load range G, meaning it has a 14 ply rating. The maximum load as a single tire is 4,080 pounds at 110 PSI. The maximum load in a dual tire setup is gonna be 3,640 pounds at 110 PSI. This has a speed rating of L, indicating a maximum speed of 75 miles per hour. Now this heavy duty black steel wheel with one, two, three, four hand holes is designed to be used in dual wheel setups.

Now this wheel does have a high offset, so it allows for the wheel to be used as either an inner wheel in this orientation, or an outer wheel in this orientation on a dual wheel setup. The offset is either a positive or negative 5.35 inches. This steel wheel is sturdy and corrosion resistant. As you can see, it does feature a black powder coat finish, and it's over an eco primer so it's going to stand up really well to rust and corrosion. And this is a hub piloted wheel, which means it will center on the hub of the axle, not on the lugs.

The pilot hole diameter is 4.77 inches. And this does require the use of flange nuts for installation. We do sell them separately on our website. And this does use wheel lug size of five eighths of an inch by 18 flange nut. The metal valve stem is included on this wheel. And the dimensions of this wheel, Looking at the diameter first, measuring bead seat to bead seat, is 16 inches. And the width, again, measuring bead seat to bead seat is six inches. So 16 inches on the diameter, six inches on the width. The wheel has a capacity of 3,860 pounds. And our bolt circle diameter, or bolt pattern, is eight on six and a half inches. And in case you don't know, the first number in the bolt pattern is the number of bolt holes, and the second number is the diameter in inches of the circle on which the bolt holes sit. So to determine the bolt circle diameter on a bolt pattern with even numbers as we have here, you're simply going to measure from the center of one bolt hole to the center of the bolt hole directly across from it. This assembly does meet the Department of Transportation specifications. And I think that's gonna wrap up our real quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
