Is a cold tire pressure of 220 too low?

No, here are the details: Generally, the cold tire pressure is between 2.2-2.5. It should be slightly higher in winter and slightly lower in summer because the temperature of the tire also affects the change in tire pressure. When the car is running on the road, the tire temperature rises quickly, and the tire pressure will be higher than the cold tire pressure. This reduces the car's grip, and the tire elasticity increases, leading to a decrease in ride comfort. If the tire pressure exceeds the critical value, it can also cause the risk of explosion. If possible, it is recommended to fill with nitrogen in summer because nitrogen is more stable, and many racing cars use nitrogen. In winter, the tire temperature does not rise as quickly, so you can inflate the tires a bit more.

I've been driving for fifteen years, and a cold tire pressure of 220kPa is a bit low. My car's manual recommends a minimum of 230. At 220, the steering wheel feels heavy, fuel consumption is slightly higher, and tire wear becomes uneven. Last time I drove long-distance with 220 tire pressure, after a month, the tire edges developed more cracks. After inflating to 250, it became more fuel-efficient and safer. I suggest you check the label on the car door or the manual. Generally, in summer, adjusting to 230-250 is fine. Low pressure not only wastes fuel but also makes the car prone to losing control during high-speed sharp turns. Don't take it lightly.

From a mechanic's perspective, a cold tire pressure of 220 kPa is on the low side. Most vehicles recommend at least 230 kPa. Low tire pressure increases rolling resistance, causing a significant jump in fuel consumption, while also generating excessive internal heat that can lead to overheating and deformation. I've seen many vehicles with 220 kPa tire pressure experience severe wear within six months, requiring premature tire replacement which ends up being more expensive. It's advisable to inflate to around 240 kPa soon. Use a tire pressure gauge for accurate measurement - don't just eyeball it. In hot weather, low pressure also affects braking distance. Safety should always come first.

As a new car owner, a tire pressure of 220kPa makes me worry about safety. My car manual states that 240kPa is the recommended level, and at 220kPa, the rear wheels feel sluggish, the car drifts when turning in the rain, and I almost rear-ended someone during an emergency brake once. I also checked the app, which showed that low pressure increases fuel consumption by 5% and reduces tire life by half a year. Now, I measure the tire pressure every month and inflate it to 235kPa before driving to feel safe. Don’t skimp on small safety matters to save money.
