Tire Pressure and Tread: The 5-Minute Safety Check
Use pressure, tread depth, spare-tire readiness, and visible damage checks to decide whether to inflate, repair, or replace.
Key takeaways
Bring pressure back to the placard value when tires are cold.
Pressure first
Tire pressure changes with temperature and use. Check pressure when the tires are cold, compare against the placard or manual, and do not use the sidewall maximum as your normal target.
Tread is the stopping-distance check
Tread helps the tire channel water and maintain grip. When tread reaches 2/32 inch, replacement is due. Uneven wear, cracks, bulges, or foreign objects are service signals even if tread depth looks acceptable.
Do not forget the spare
A fully stocked car is still vulnerable if the spare tire is flat or missing. Check the spare, inflator, jack, lug wrench, and wheel-lock key before a long drive.
