With the Fall fast approaching we are starting to see many used tires pop up on Facebook, some are genuine good tires, some the seller doesn't understand that the tires they are selling are no longer road worthy even if they "Look" good. Some are trying to scam junk and will vanish the second they get your $$$
When buying used tires, inspect for sufficient, even tread depth (more than 4/32 inch is recommended for winter at the 4/32 mark is a just barely pass), and check sidewalls and bead areas for any cracks, bulges,
cuts, or dry rot. Determine the tire's age using the DOT code on the sidewall, avoiding tires older than six years, and check the entire tire for signs of improper
repairs. Ensure the tire's size, load index, and speed rating match your vehicle's specifications.
1. Check the Age
Find the DOT code:
Look for the letters DOT on the tire's sidewall, followed by a string of numbers and letters.
Determine the manufacture date:
The last four digits of the DOT code indicate the week and year of manufacture. For example, "1819" means the tire was made in the 18th week of 2019.
Understand the risk:
Rubber degrades over time; tires older than six years can begin to dry rot, even if the tread is good.
2. Inspect the Tread
Use a tread depth gauge: The recommended minimum tread depth is 4/32 of an inch.
Look for uneven wear: Uneven wear patterns, such as "cupping" or "feathering," can indicate problems with the vehicle's alignment, suspension, or inflation.
3. Examine for Damage
Sidewall damage:
Check for cracks, dry rot, bulges, or cuts on the sidewalls. Damage here can compromise the tire's structural integrity.
Tread damage:
Look for any cuts, punctures, or missing chunks of rubber.
Interior inspection:
Check the tire's inner liner for signs of damage, exposed cords, or rubber dust, which suggest the tire is unsafe.
Repair check:
Inspect the tire for patches or plugs, especially on the shoulder or sidewall, as these areas cannot be safely repaired and can lead to a blowout.
4. Verify Bead and Fitment
Check the bead area:
The bead is the inner rim of the tire that seals to the wheel. Inspect it for damage, wear, or rot that could prevent an airtight seal.
Confirm vehicle fitment:
Ensure the used tire's size, load index, and speed rating match the specifications for your vehicle.
Consider reputable sellers:
Buying from a reputable tire shop or retailer can provide more confidence. Winter tires are an investment in keeping your vehicle out of the ditch and out of the ICBC write off yard. Think about what you would do if you lost your vehicle.
