Tyres naturally lose air over time, which means you need to adjust their pressure regularly (we recommend monthly), no matter what type of tyres they are (summer, winter, or all season). Periodically checking the pressure will also ensure you notice any unusual loss of pressure in one tyre compared to the others, which could indicate a leak.
It’s also advisable to check your tyre pressure before heading out on a long road trip or if the vehicle is carrying a heavy load. Remember to measure tyre pressure when your tyres are “cold” (after driving your vehicle less than 3 km).
