Look at your state or region'southward tire tread requirements provided past the transportation department.^[one]

   • Call or email your country's department of transportation or visit their website to locate tread laws.
   • In some U.S. states, tires are considered to be legally worn out when they have decreased to ¹⁄₁₆ inch (0.16 cm) of their remaining tread depth.
   • In the U.K., the minimum depth for tire tread is 0.0456 inches (1.sixteen mm) across the central three/iv of the tread around the whole tire.

2. 2

   Supplant your tires if the tread bar is flush with the tire tread. All tires sold in the U.S. and well-nigh other countries have tread clothing bars—minor horizontal bridges that form between your treads at a lower depth. Equally your tires vesture, these bars get flush with the tread. When the tire tread is even with these habiliment bars, information technology ways the tread is worn to ²⁄₃₂ inch (0.16 cm) and needs to exist replaced immediately.^[two]

   • When yous look at your tire article of clothing bars, be certain to look at the entire surface of the wheel and not just i isolated location.

   Check the habiliment of your tread quickly by inserting a Lincoln penny into information technology. Take a Lincoln penny and identify information technology upside down with Lincoln facing you lot in the middle of the tread at the thickest part of the tire. If you lot can see the very top of Lincoln'southward head or the copper above it, supersede the tire immediately. If y'all cannot see the pilus on the elevation of Lincoln's head—significant the tire tread is at to the lowest degree as deep every bit his forehead—your tire does not need replacing nevertheless.^[3]

   • If you have a Canadian nickel, insert it between the tread with Queen Elizabeth'due south crown facing down. If the superlative of her crown is visible, the tire is below ²⁄₃₂ inch (0.sixteen cm) and needs to exist replaced.
   • Tires do non article of clothing evenly, so be certain to insert the coin at several points from the outside to the inside of your tires. Tires generally wear more on the within, but over-inflated tires volition wear more in the middle.
   • For a more accurate tread depth measurement, utilise a tread depth approximate.

4. four

   Use a tread depth indicator for a more than authentic measurement. Place the probe of the indicator in the center of one of the tire grooves on the outskirts of the tread. Remove the gauge by the barrel—taking care not to touch on the probe—and annotation the tread depth. Go along this process for locations around the center tire grooves tire at least 15 inches (38 cm) apart and so boilerplate the numbers. Replace the tires if the depth is less than ²⁄₃₂ inch (0.16 cm). ^[4]

   • Repeat this process for the outer and inner circumferential grooves, so average those numbers besides.
   • To average numbers, divide the total by the number of private measurements you lot made along the tread.
   • Before using the tread depth indicator, push the tread depth gauge against a flat, hard surface and be sure it hits aught when it fully compresses.

   Bring your car in for maintenance if you find irregular tread wearable.

A bulge indicates that the rigid internal frame of the tire has been damaged and cracked, assuasive air pressure to reach the flexible outer layers of the tire. Any tires with sidewall bulges should be replaced immediately, regardless of the tread status. ^[6]

   • Such harm could exist caused by driving through a large pothole, driving over a curb, or by driving with depression tire pressure.

   • If you experience vibrations in the absence of tread damage, endeavour balancing and aligning your tires' shock absorbers.
   • If y'all notice tire vibrations forth with other tire damage indicators similar abnormal bulges and irregular tread wearable, yous probably take to replace your tire.
   • If you observe that your tires are cupped—meaning they have a cupped or scalloped appearance effectually the tire—they likely aren't being rotated enough.

4. 4

   Check for dry rot and have afflicted tires inspected or replaced. If you see little cracks all over your tires, it ways that the rubber is breaking down.

If the tire is more than than 6 years former, replace it.^[ix]

   • If you're having problem finding the number, wait for the initials DOT, followed by other messages and numbers. The code should announced post-obit dot and will non contain any letters.
   • Remember that although 10 years is the maximum service life for tires—which means since the appointment they were manufactured—this should never exist used as the maximum bulldoze time.
   • Ever err on the side of circumspection if yous suspect your vehicle has tires that are over 6 years of historic period.
   • Always change your tires if the tread is below the minimum depth recommendation, which is oftentimes ²⁄₃₂ inch (0.xvi cm).
