Keeping semi-truck tires in excellent condition is vital to the safety of everyone on the road. When managing a fleet of trucks, implementing a regular tire inspection and replacement schedule can prevent problems like blowouts that could result in serious accidents. Here are a few signs that you need new tires for a semi-truck. 

When to Put New Tires on a Semi-Truck 

1. Tread Wear 

Truck tires should have at least 1.6 millimeters of tread depth. Trucks that often drive on wet or slippery roads should have twice that depth. 

Have your drivers check the tread depth regularly using an accurate gauge. Most new tires include a wear indicator that becomes more visible as the tires wear out. If the indicator appears on any tire, the tire should be replaced. 

2. Excess Vibration

Although it's reasonable to expect some shaking as the truck moves down the road, it's easy to tell when there's excess vibration. A new or unusual vibration could mean that the tires have worn unevenly, there's a problem with the alignment or balance, or there's an issue within the tires or axle that isn't immediately apparent. Have a mechanic investigate the issue and put on new tires if needed. 

3. Visible Damage 

Truck tires that are worn or old often have visible signs of damage, including cracks and blisters. Cracks and splits in the sidewall of the tire are usually visible to the naked eye and indicate that the tire is leaking. Leaking truck tires are vulnerable to blowouts, so they need to be repaired or replaced right away. 

The same precaution applies to blistering tires. Any bulge or blister on the outer surface of the rubber is a weak spot. The tire will need to be replaced to prevent a blowout.
