How to Tell if it is Time for New Commercial Tires

Commercial vehicles operate under tough conditions, so maintaining proper tire health is critical for safety and efficiency. Over time, even the most durable commercial tires wear out, and knowing when to replace them is key to preventing accidents, breakdowns, and costly downtime. At E-Z Tires, a mobile tire company near LA, we help you stay on top of tire care, but it’s also important to know how to spot the signs that it’s time for new commercial tires. Below, we’ll cover the key indicators, including tread depth, tire damage, and uneven wear.
How to Test Tread Depth
Tread depth plays a crucial role in vehicle safety, especially for commercial vehicles that handle heavy loads. The legal minimum tread depth is 4/32 of an inch for steer tires and 2/32 for other tires. You can check tread depth using a tire gauge or the penny test: place a penny in the tread groove with Lincoln’s head facing down. If the top of Lincoln’s head is visible, your tread is worn, and you should replace the tire.
Visible Tire Damage
Commercial tires endure tough conditions, which can lead to visible sidewall damage, such as cuts, cracks, or bulges. If you spot any of these, it’s time for a replacement, as damaged tires are at risk of blowouts.
Uneven Tire Wear
Uneven tread wear is often caused by improper inflation, misalignment, or suspension issues. If your tires show signs of uneven wear, they may need replacement. Regular inspections and tire rotations can help prevent this.
Frequent Air Loss
If you find yourself constantly refilling a tire, it could indicate a slow leak or internal damage. Frequent air loss is a sign the tire may need to be repaired or replaced to maintain vehicle safety and fuel efficiency.
Tire Age
Even if your tires look fine, they should be replaced after about six years. Over time, rubber deteriorates, which can cause cracks and weak spots, making older tires unsafe.
