We've talked about how important winter tires are to driving safety, but tire inflation can play just as important a role.
According to Transport Canada:
"[Tire] underinflation increases rolling resistance, which reduces tread life and increases fuel consumption. It can also lead to sudden tire failure. Without enough air, the sides of a tire bend and flex too much. This builds up heat, which can cause serious damage. Operating a vehicle with just one tire underinflated by 56 kPa (8 psi) can reduce the life of the tire by 15,000 km and can increase the vehicle’s fuel consumption by 4%."
In the winter, cold temperatures cause tires to lose pressure, leading to underinflated tires. Stay on top on your tire pressure with these tips:
