Is the front tire pressure higher or the rear?

[Geraldine]

Generally, the tire pressure of the front wheels is higher than that of the rear wheels because the front of the car houses the engine, making the front part heavier. This results in slightly higher tire pressure in the front wheels compared to the rear. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends tire cords, reducing tire elasticity and increasing the load during driving; decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts, leading to a flat tire. Hazards of insufficient tire pressure: Increases friction with the road surface, raising fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a flat tire; increases tire deformation, making the sidewalls prone to cracks and generating flexing motion, leading to excessive heat, rubber aging, cord fatigue, and breakage. It also increases the tire's contact area, accelerating shoulder wear.
