How to Choose the Right Used Tires
Understand Why You're Buying Used Tires
Before you start shopping, ask yourself why you're going the used route. Some common reasons include:
- Saving money compared to new tires
- Replacing one or two tires instead of a full set
- Selling or trading in a vehicle soon
- Temporary use (like a spare or backup)
Knowing your purpose can help you determine how much to invest and what level of quality you need.
Check the Tread Depth
One of the first things you should inspect is the tread depth — this determines how much life the tire has left. New tires typically have 10/32” to 11/32” of tread. A used tire with less than 4/32” is too worn and should be avoided.
You can check tread depth using a:
- Tread depth gauge (ideal for accuracy)
- Penny test: Insert a penny into the tread with Lincoln's head facing down. If you can see the top of his head, the tire needs to be replaced.
Inspect for Uneven Wear
Uneven tread wear can indicate alignment problems, poor suspension, or underinflation in the tire’s past. This can reduce performance and lifespan. Avoid tires that show:
- One-sided wear
- Cupping (wavy tread)
- Flat spots
Even wear across the tread means the tire has been properly maintained and is a safer choice.
Check the Sidewalls
The sidewalls of the tire are just as important as the tread. Look for:
- Cracks
- Bubbles or bulges
- Cuts or dry rot
Any of these signs may indicate internal damage and could lead to a blowout or failure.
Look at the Tire’s Age
Every tire has a DOT code printed on its side. The last four digits represent the week and year the tire was manufactured. For example, a DOT code ending in “4219” means the tire was made in the 42nd week of 2019.
Most experts recommend avoiding tires older than 6 years, even if they appear in good condition. Rubber breaks down over time, which can compromise safety.
Match the Tire Size and Type
Make sure the used tires you’re considering match the specifications recommended for your vehicle. Check your:
- Owner’s manual
- Door placard (inside the driver’s side door)
The tire size should match your car’s requirements (example: P215/65R15), and the type (all-season, performance, snow, etc.) should suit your driving conditions.
Consider the Brand and Model
Well-known tire brands usually offer higher quality, even when used. While lesser-known brands can be more affordable, a reputable brand may provide better performance and durability in the long run.
It’s also helpful to research reviews on specific tire models to understand their performance on wet roads, handling, noise, and comfort.
Buy from a Trusted Seller
Not all used tire sellers offer the same level of quality and transparency. Look for:
- Reputable tire shops or auto centers
- Clear return or exchange policies
- Tires that have been inspected and pressure-tested
Avoid tires sold from unknown sources unless you can fully inspect them yourself.
Compare the Cost vs. Value
Used tires can save you a lot of money, but they should still offer decent tread life and safety. If a used tire only has 20–30% tread remaining and costs nearly as much as a new one, it’s not worth it.
Make sure the price reflects the condition.
Ask About Repairs
Some used tires may have had patches or plugs. While one properly repaired puncture in the tread area is usually safe, multiple repairs or sidewall patches are red flags. Be sure to ask:
- Has the tire been patched or repaired?
- Where was the damage located?
Tires with sidewall repairs should be avoided entirely.
