Can a tire pressure of 220 run on the highway?

A tire pressure of 220 can run on the highway, but it is not recommended. Generally, the tire pressure value within the range of 2.2 to 2.5 BAR is safe. In summer, when temperatures are high, the tire pressure, which is within the normal range when the car starts, may actually rise. Therefore, in summer, it is advisable to maintain a slightly lower tire pressure within the normal range, while in autumn and winter, it can be controlled at 2.5 BAR. Tires are often used under complex and demanding conditions. During driving, they endure various deformations, loads, forces, and the effects of high and low temperatures. Therefore, they must have relatively high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have relatively high wear resistance and flex resistance, as well as relatively low rolling resistance and heat generation.
From my perspective as an experienced driver, a tire pressure of 220 kPa is on the low side and not ideal for prolonged high-speed driving. The standard tire pressure typically ranges between 230 to 250 kPa, so check the door label or manual for confirmation. Low pressure causes greater tire deformation, leading to rapid heat buildup from high-speed friction, increasing the risk of blowouts in summer and making handling feel floaty and unstable. While 220 kPa is still acceptable for short high-speed trips, keep your speed below 100 km/h to avoid excessive heat buildup in the rear tires after several continuous hours. I always check tire pressure before long trips—it takes just a few minutes with a tire gauge, and filling up at service stations is quick and hassle-free. Long-term neglect can lead to higher fuel consumption, uneven tire wear, and premature tire failure. Safe driving should never be taken lightly. Make it a habit to check regularly to prevent major issues.
