It may be time for new tires if they are more than six years old, or if you notice any of the following signs:
- The tread has worn down to less than 3/32"
- Bulges, blisters, or bubbles
- Cracking in the tread grooves
- Punctures, cuts, snags, or separation in the tire tread, shoulder, or sidewall
- Sudden loss of tire pressure
- Poor handling or traction on slippery surfaces
- Pulling to one side while driving
- Sudden vibration while driving
Tires that have been driven on while flat, or are 10 years old or older, should be immediately replaced.
