What is a good tire pressure for hot weather?
If tires are warm from being driven, set pressures 4 psi above recommended in the morning and 6 psi if checked and set in the afternoon.
Does tire pressure go up or down with heat?
Heat can have a huge effect on your tires. The air pressure in tires increases as the temperature goes up. Scientists have figured out that for every 10 degrees (Fahrenheit) that the temperature rises the tire pressure will increase by one pound per square inch (PSI).
How much does tire pressure change with temperature?
A good estimate is for every 10° fluctuation in air temperature, vehicle tire pressure will adjust by about 1 psi. So if outside air temperature decreases 30° from your last tire pressure adjustment, expect tire pressure to drop about 3 psi.
What should the tire pressure be in a cold car?
Most passenger cars will recommend 32 to 35 psi in the tires when they’re cold. The reason you check them cold is that as tires roll along the road, friction between them and the road generates heat, increasing both the temperature and the air pressure.
Where can I find the tire pressure on my car?
If there’s no sticker on the door, you can usually find the specs in the owner’s manual. Most passenger cars will recommend 32 psi to 35 psi in the tires when they’re cold.
Why is it important to know the air pressure in your tires?
Finding the Right Tire Pressure for Your Car. Getting the right air pressure in your vehicle’s tires is crucial to ensuring a safe, efficient, and comfortable drive. It will also maximize the life of your tires, saving you money by stretching the time between expensive tire replacements. Fortunately, keeping your tires properly inflated is easy.

What should the air pressure be in a Tire Rack?
Tire Heat Generated While Being Driven (or at speeds of less than 45 mph) .* Set 4 psi above vehicle manufacturer’s cold inflation recommendations. Heat Generated While Being Driven Extensively (or at sustained speeds greater than 45 mph) .* Set 6 psi above vehicle manufacturer’s cold inflation recommendations.
If there’s no sticker on the door, you can usually find the specs in the owner’s manual. Most passenger cars will recommend 32 psi to 35 psi in the tires when they’re cold.
