What Should Tread Depth Be on Semi Truck Tires?

Semi truck tires are some of the most important components of any truck. They get a lot of wear and tear, so it’s important to pay attention to the tread depth on them.

Properly maintaining the tread depth on your semi truck tires will ensure you have a safe and reliable ride.

Tread depth is an indication of how much life a tire has left in it. When new, semi truck tires typically come with 10/32″ of tread depth, which is also considered “full-depth”. The minimum legal tread depth for semi truck tires is 4/32”, but this may not be enough to keep your vehicle safe in all types of road conditions.

When measuring the tread depth of your semi truck tires, it’s important to use a dedicated tire tread depth gauge. These gauges can be purchased at any auto parts store and are relatively inexpensive. All you need to do is insert the gauge into each groove of the tire’s tread pattern and read off the measurement.

It’s best to check your tire tread depths every month or two, as well as before long trips or when driving in wet weather conditions. In general, when your semi truck tires have less than 4/32” of tread left, they should be replaced due to decreased traction and increased risk of hydroplaning.

What Should Tread Depth Be On Semi Truck Tires?

The ideal tread depth for semi truck tires should be 10/32″, which is considered “full-depth” when new. The absolute minimum legal requirement for semi truck tires is 4/32″, but this may not provide enough traction or safety in certain road conditions. It’s best to check your tire tread depths at least every month or two and replace them when they reach 4/32″ or less to ensure optimal safety and performance on the road.
