What is the normal range for tire pressure in summer?
2 Answers
The normal range for tire pressure in summer is between 2.2-2.4 bar. As temperatures and road surface temperatures rise, tire pressure can easily increase during high-speed or long-distance driving. Excessive tire pressure may lead to brake failure and can cause tire blowouts when encountering road protrusions or depressions. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates uneven wear of 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 vehicle 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 and blowouts.
I think the range for summer tire pressure is generally around the manufacturer's recommended value, which is that small line of text on the B-pillar or fuel cap. I check it often, and it's usually around 30 to 35 PSI. In summer, the heat causes tires to expand, and increased tire pressure can lead to blowouts, so I always use a tire pressure gauge before each season change to ensure it's 2-3 PSI below the standard. For example, when I drive on the highway, I make it a habit to measure the pressure when the tires are cold, as hot tires can give inaccurate readings. The key is to maintain balance—too high reduces grip, while too low increases fuel consumption and wear. Based on my experience over the years, checking the tire pressure every few weeks is the safest approach, especially before heading out in hot weather. It significantly reduces the risk of accidents, saving money and ensuring safety. I recommend finding a reliable tool or visiting a repair shop for a free check—don’t skimp on this small but crucial task.
