SIGNS THAT INDICATE YOU HAVE TO CHANGE YOUR CAR TIRES
1. Understand that the primary function of tread on a tire is to divert water from beneath the tire to improve traction and avoid
hydroplaning on wet roads.
2. Look at the tread pattern. These are small bridges that form between your treads.
3. Check the tread by using the penny test. 2/32-inch minimum tread depth requirement. which require motorists to replace a tire when the tire wears down to that depth.
4. Use a tread depth indicator or gauge. You can use a special tread depth indicator or gauge tool to measure your tires tread.
5. Make note of any improper tread wear, improper inflation pressure, and out-of-spec tire alignment.
6. Check for any abnormal bulges or “bubbles” in the sidewall.
7. Notice a vibration in the steering wheel and check for dry rot. If you see little cracks all over your tires. it means that the rubber is breaking down.
8. Replace the tires at least every 6 years. If you’re not sure. the minimum replacement time that is recommended by the NHTSA is six years regardless of use. with 10 years being the maximum service life for tires.
