What is the standard tire pressure in summer?

[Tessa]

In summer, the normal tire pressure is generally between 2.2-2.5 kilopascals. The following is relevant information about tire pressure: 1. Excessive tire pressure: Reduces the contact area between the tire and the ground, leading to a dramatic increase in pressure and wear per unit area, which can easily cause brake failure, tire blowouts when encountering ground protrusions or depressions, damage to the vehicle's suspension system, and discomfort while riding. 2. Insufficient tire pressure: Increases the contact area between the tire and the ground, causing abnormal temperature rise inside the tire during driving. At the same time, severe deformation of the tire sidewall accelerates the aging of internal steel wires and fabric layers, thereby creating hidden dangers for tire blowouts, increasing fuel consumption, and reducing tire lifespan.

I just researched this before a road trip a few days ago. I specifically checked the manual and found that tire pressure in summer should actually be increased by 0.1-0.2 bar compared to normal conditions. The mechanic told me last time that tire temperature rises quickly when driving, and low tire pressure makes blowouts more likely. However, I prefer measuring tire pressure in the morning before driving when the tires are cold for more accurate readings. Remember to add 0.2 bar when fully loaded - last family trip with a packed trunk showed visibly flattened tires due to insufficient pressure. It's best to check with a mechanical gauge monthly as TPMS can sometimes malfunction.

An experienced mechanic taught me a mnemonic: 'Check the tire pressure on the car's pillar label and reduce it by 20%.' In summer, road temperatures can easily reach 50-60 degrees Celsius, and tire pressure can increase by more than 0.3 bar during highway driving. Last time, I inflated my tires to 2.3 bar, but the pressure soared to 2.6 bar after exposure to the midday sun. Now, I always inflate to the manufacturer's recommended pressure, which is usually indicated on a sticker on the door frame or fuel cap. Never follow the online advice to intentionally deflate your tires, as too low pressure can cause the tire sidewalls to wrinkle, making them more prone to overheating.

Lessons learned from years of car modification: Tire pressure is definitely not a fixed value. Different tire compounds and seasonal changes have significant impacts. In summer, it's recommended to maintain 2.2-2.5 bar when tires are cold, but always refer to the manufacturer's label on the door jamb. Once I used performance tires that safely reached 3.0 bar during summer mountain runs, while standard tires become dangerous above 2.8 bar. Always keep an inflator with temperature display - it's far more reliable than regular pressure gauges.
