What Tires Are Made Of Steel Belts: The steel belts run longitudinally around the circle of the tire. Steel belts are made up of thin steel wires that are woven together into thicker cords, then woven again to form large sheets of braided steel. The sheets are then sandwiched between two layers of rubber. Most passenger tires contain two or three steel belts.

Common wheel and tire terminology You can also check the tread wear indicator. You can find the tread wear indicator less than an inch (2/32 of an inch) from the bottom of the tread groove. When the tread wears down to become even with this level, the tire should be replaced.

New Tire Tread Depth As an example of different tire diameters resulting from tires worn to different tread depths, we compared two 225/45R17-sized tires, a new tire with its original tread depth of 10/32-inch and a second tire worn to 8/32-inch of remaining tread depth.

Tread Depth Another way to check tread depth is to look at the treadwear indicator bar that's molded into your tires. The bars are located at the bottom of the tread grooves in several locations around the tire. When these bars become visibly flush with the adjacent ribs the tire has no more than 2/32 of tread remaining. This is a visible indication that the tire should be replaced.

Tread Pattern Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Bolt patterns can be 4-, 5-, 6-, or 8-lug holes. A bolt circle of 4x100 would indicate a 4-lug pattern on a circle with a diameter of 100mm.

Tire rotation patterns If your vehicle has differently sized, non-directional tires on the front and rear axles, it will use the side-to-side pattern shown to the right above. The front tires move to the opposite side of the front axle and the rear tires go to the opposite rear side.. Front-to-back. Directional tires are designed and constructed so that they always rotate in the same direction due to their tread pattern. If your tires are directional, they should only be rotated from front to back (or vice-versa) on the same side of the vehicle.

- Clearance. The numbers in the tire size refer to its width, aspect ratio, and wheel diameter. 205/55R16 means the tire is 205 mm wide, has an aspect ratio (that is, the width divided by the height) of 55%, and fits on a 16 rim.R means radial tire. They're all radials nowadays.

Tire Specs Explained: Tread Depth Dedicated winter / snow tires and light truck tires typically are deeper (for light truck tires, how much deeper depends on the tire's tread type, Highway Rib, Highway All-Season, Off-Road All-Terrain or Off-Road Maximum Traction). In most States when they reach 2/32 of remaining tread depth. For example, a typical tire that starts with 10/32 of original tread depth has only 8/32 of useable tread depth. Its useable tread depth is calculated by subtracting a worn out tire's 2/32 from the new tire's original depth of 10/32.

Truth about tread depth Truth about tread depth. Varying standards for minimum tread depth is something that continues to be confusing for those new to the industry. According to the Federal Motor Carrier Safety Administration (FMCSA), the minimum tread depth for truck tires is 4/32nds of an inch on the front axle and 2/32nds of an inch for all other wheel positions. Law enforcement officials often ticket drivers when the tread depths on their vehicles fall below those limits.

Tire rotation patterns There are specific tire rotation patterns that should be followed, based on these factors: 1  Whether your tires are directional or non-directional (directional tires have a tread pattern that is designed to rotate in one direction only).2  Whether your vehicle is front-wheel, rear-wheel, 4-wheel, or all-wheel drive.. Front-to-back. Directional tires are designed and constructed so that they always rotate in the same direction due to their tread pattern. If your tires are directional, they should only be rotated from front to back (or vice-versa) on the same side of the vehicle.
