As electric vehicles (EVs) become increasingly popular in China and across the globe, proper tire maintenance is more important than ever. Tires are the only part of your car that touches the road, meaning they directly influence safety, comfort, and efficiency. For Chinese EV owners, summer heat and long-distance driving can make tire care even more critical. Many drivers think that simply releasing some air when tire pressure rises in hot weather is the best solution—but this assumption can be dangerously wrong. Let’s explore the proper practices every EV owner should know.
When manufacturers design and test tires, they carefully calculate pressure ranges that take into account temperature changes across seasons. This means the recommended pressure printed in your car’s manual or on the door frame already factors in hot summer conditions. Just as a pressure cooker comes with a maximum safety threshold, tire pressure standards also ensure safety under various weather conditions. For Chinese electric vehicles, engineers anticipate not only heat expansion but also the additional weight of battery packs, so the margins are designed to keep your EV safe without frequent adjustments.
Ironically, underinflated tires are a much bigger threat than slightly overinflated ones. A veteran mechanic once shared that most blowout accidents he has repaired came from tires with low pressure, not high. When tire pressure is too low, the sidewalls flex excessively, causing friction and heat buildup. Over time, the rubber weakens, making the tire prone to sudden failure. For EVs, which are heavier than traditional gas-powered cars, this risk increases. A blowout at highway speed can cause severe damage or even life-threatening accidents. Keeping tires properly inflated is a basic yet crucial line of defense.
So, when should you actually release air? The rule is simple. If cold tire pressure exceeds the standard by more than 0.3 bar, it’s reasonable to adjust. Similarly, if long highway driving pushes pressure over 3.5 bar, you should release a little. However, avoid the mistake many drivers make: misjudging normal pressure as excessive. One EV driver saw 2.9 bar on his monitor, assumed it was too high, and lowered it to 2.3 bar. The result? A sidewall rupture at high speed, leading to serious loss. Tire pressure monitoring systems (TPMS) in most Chinese EVs are designed to alert you only when real danger occurs, so trust the standards rather than assumptions.
Balance matters just as much as absolute pressure. If the left and right tires differ by more than 0.2 bar, the braking distance can increase by over 1.5 meters. In emergency stops, this extra distance could be the difference between safety and collision. Uneven tire pressure also causes uneven tread wear, affecting handling and reducing lifespan. For EV owners, who already enjoy instant torque and powerful acceleration, imbalance can compromise traction and stability. Regularly checking all four tires and adjusting them equally ensures smoother rides and greater control.
On hot summer days, some drivers think splashing cold water on tires will quickly lower their temperature. Unfortunately, this practice is very dangerous. Rapid cooling can cause the rubber to contract sharply, creating micro-cracks invisible to the eye. These small damages may later expand under stress, leading to sudden failure. Experts recommend instead parking in shaded areas or driving moderately to allow natural cooling. EVs already generate less heat from the powertrain compared to gasoline cars, but the heavy load of batteries means tires still face considerable stress. Proper cooling methods protect long-term durability.
Summer heat, long drives, and heavy EV structures all put pressure on your tires. The smart approach isn’t blindly letting out air but regularly checking cold tire pressure, keeping it within the recommended range, and maintaining balance between all four tires. Cooling should always be gradual, never forced. By respecting these details, you ensure safety, performance, and peace of mind on every journey.
