What is the normal tire pressure difference between tires?

[EllianaAnn]

Tire pressure differences between tires within 0.1bar are normal, but exceeding 0.1bar doesn't necessarily require adjustment. Factors like tire pressure monitoring system errors and varying vehicle loads can temporarily cause pressure variations. The hazards of excessive tire pressure include: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Increased steering wheel vibration and deviation, lowering driving comfort; 3. Accelerated wear on the central tread pattern, shortening tire lifespan; 4. Increased vehicle vibration, indirectly affecting other components' longevity. Factors affecting tire pressure: 1. Seasonal factors: In winter, adjust 0.2bar higher than standard pressure; in summer when parked outdoors, keep 0.1bar lower to prevent high-temperature blowouts; 2. Measurement conditions: Cold and hot tires show different pressures, with a typical 0.3bar difference to note during measurement.
