A used car may have tires with plenty of tread but still need replacement because of age, cracking, damage, or uneven wear.
Find the tire date code
The tire sidewall includes a manufacturing date code. The final four digits identify the week and year the tire was produced. Check each tire because they may not all be the same age.
Inspect condition
Look for cracking, bulges, cuts, repairs, exposed cords, or unusual wear. Compare inner and outer tread areas, not only the easiest part to see.
Check for matching tires
Different brands or significantly different tread depths can matter, especially on vehicles with all-wheel drive.
Tires are a safety and ownership-cost item, so include their condition in the purchase decision and budget.
