Maintaining your semi truck's trailer tires is essential for both safety and efficiency on the road. As the miles add up, wear and tear can compromise the tires' performance, leading to costly delays and unsafe driving conditions. At Billy Bob’s Repair & Tire, we provide expert big rig tire services in the greater San Antonio, TX area. Here are five signs that it’s time to replace your semi truck’s trailer tires. 

Tread Depth Is Low

Tire tread depth is crucial for traction, especially in wet conditions. If the tread on your trailer tires is worn down to 2/32 of an inch or less, it’s time for replacement ASAP. And it’s generally recommended that, to maintain optimal safety, you should go ahead and replace trailer tires at 4/32 of an inch. Tires with low tread are more prone to hydroplaning and have less grip on the road, increasing the risk of accidents.

Visible Cracks and Bulges 

Cracks or bulges on the sidewalls of your tires are a clear sign that they need replacing. These issues often result from the rubber aging, exposure to harsh elements, or damage from impacts with curbs or debris. Driving with tires in this condition could lead to a blowout, which can be extremely dangerous.

Uneven Wear Patterns 

Uneven wear on trailer tires is a sign of improper alignment, incorrect tire pressure, or suspension problems. If you notice one side of the tire is more worn than the other, it’s not only time to replace the tires but also to check your trailer's alignment and suspension to prevent the issue from recurring.

Frequent Air Pressure Loss 

If you find yourself frequently inflating your trailer tires, it’s a sign they might be nearing the end of their lifespan. Repeated loss of air pressure can indicate internal damage or worn-out rubber. Driving with underinflated tires reduces fuel-efficiency and can lead to premature tire failure.

Age of the Tires 

Even if the tread looks fine, trailer tires should generally be replaced when they’re between 3 and 5 years old. Over time, the rubber in tires degrades due to exposure to sunlight and extreme temperatures. This can cause the tires to weaken, increasing the likelihood of blowouts.
