Use the vehicle’s pressure recommendation
Check the tire placard, commonly near the driver’s door, or the owner’s manual. The number on the tire sidewall is not the vehicle’s recommended operating pressure. Check pressure when tires are cold.
Look for changes
Watch for uneven wear, cuts, cracks, bulges, or objects embedded in the tread. A warning light or vibration is a reason to investigate, not a substitute for a pressure and condition check.
Get help when unsure
Ask a tire professional about damage, wear, age, and the correct replacement size and load rating. Do not rely only on how much tread appears to remain.
Should I inflate to the number printed on the tire?
Use the vehicle manufacturer’s recommended pressure on the placard or in the owner’s manual, not the tire’s maximum pressure marking.
