New car parts can be expensive. As an alternative, you can go to a salvage yard to buy used auto parts at discounted rates. If you're looking to purchase used tires, you may wonder how you can tell whether they’re fully functional. Here are a few quality-control strategies to use when you receive your pair.

How to Tell if a Used Tire Is High-Quality

1. Has No Punctures

The best options will have no visible patches. However, many used auto parts have gone through a few repairs, and this doesn't mean they aren’t durable. If you see a minor plug or patch, the unit is still safe if you don’t feel any air escaping.

2. Is Smooth

A tire with a separated belt will look bumpy or wavy on the surface. This usually occurs when the car has driven over irregularities, causing damaging impact.

Run your hand over the surface if you can't see any waviness on the sidewall and treads. If the tire isn't fully inflated, press harder to feel for bumps. If it feels smooth and even, it’s safe.

3. Passes Tread Depth

Check the tread depth of the tires using the penny test. Place a penny in a gap between two tread blocks, with Lincoln's head facing down.

If you can't see the top of his head, it passes the test. If the head is fully visible, the tread is overly worn.

4. Doesn’t Have Exposed Cords

You shouldn’t be able to see any lines or strings around the unit. Exposed cords could mean improper air pressure or that the previous owner’s wheels were bent. These factors will damage and misshape the tires, which means you won't have enough traction on the road.
