Pre-Trip Inspection - Tires
- First listen for audible leaks.
- Make sure the tire is not in contact with any other part of the vehicle.
- The tire pressure must be at 100 P.S.I (110 for super singles). Any more than a 10% variance is not compliant and you risk damage to the wheel, rim, and tire if you drive on it continuously.
- Do not kick the tires or use a tire “thumper”. Only by measuring the air pressure with a tire gauge can you be certain the inflation pressure is correct.
- Steer tires are required to have a minimum tread depth of 4/32 inches. All other tires are required to have a minimum tread depth of 2/32 inches.
- A tire is considered defective if any two major grooves (any groove with a tread wear indicator) are under the legal tread depth and adjacent to each other. It doesn’t matter if the rest of the tire is fine as this indicates a wear pattern.
- Remember: The steer tires steer your truck, which is why they need more tread depth.
- There should not be any belt material or casing ply showing in the treads. If so the tire is worn through and at risk of a rupture.
- Make sure the side wall is not cut, worn, or damaged to expose the steel or fabric ply.
- Tires cannot have observable bumps, bulges, or knots; meaning the inner ply is ruptured and the tire is at risk of rupturing at any time.
- A tire can have a bulge of less than 3/8 inch if it is a properly marked repair and not on the steer tires.
- Make sure the tire does not have a recap decaying or separating from the tire. Steer tires cannot be recapped.
- Valve stems are not damaged and are covered.
