Is Tire Pressure Higher in Winter or Summer?

[SophiaMarie]

Winter tire pressure should be slightly higher than in summer due to thermal expansion and contraction. Since the weather is colder in winter, the tire pressure can be adjusted upward by 0.1 based on the normal value. Below are the methods for checking tire pressure and the hazards of both overinflation and underinflation: Methods for Checking Tire Pressure: The most standard tire pressure value can be found on the tire pressure label located on the driver's side front door frame, which indicates the original tires and their corresponding tire pressures. The tire pressure data refers to the cold tire pressure, which applies to both summer and winter tires. Hazards of Overinflation or Underinflation: Both underinflation and overinflation can shorten the lifespan of tires. Underinflation increases tire deformation, making the sidewalls prone to cracks. It also causes excessive flexing, leading to overheating, accelerated rubber aging, and even blowouts. It increases the tire's contact area, accelerating wear on the tire shoulders. Overinflation, on the other hand, causes excessive tire expansion, reducing elasticity. If subjected to significant impact, the tire may burst. Additionally, overinflation accelerates wear on the tire tread.
