Tire Pressures
Why this is important?​
The most frequent cause of tire failure is under-inflation. Even extreme under-inflation can be difficult to detect by mere visual inspection - don't depend on it, use a personal tire pressure gauge. Under-inflated or overloaded tires generate high levels of destructive, internal heat, which could cause your tires to blow out. Extreme under-inflation can even unseat the tire from the rim while your vehicle is in motion.
​
What's included?
Measure tire pressure on all four tires, and ensure that it meets the factory specification for the correct size tire/car.
Having an accurate and easy to read tire gauge is the best tool to help ensure that you have the correct tire pressure in your car at all times. Canadian Tire offers many easy to use and read gauges.
Check your owner's manual for the recommendations for your vehicle. They can also be found labeled on door edge or post, glove box or fuel filler doors depending on make/model.
​
When to have this done
Check tire pressures at least twice a month -- especially after sudden temperature changes. Tire inflation pressure drops 1psi for every 5.5°C drop in outside temperature. Check inflation when tires are COLD: when the vehicle has been driven less than 2km.

Did you know: Correct air pressure can help improve vehicle safety, fuel economy, tire life and braking distance.
