What is the recommended tire pressure for Corolla in summer?
2 Answers
Toyota's new Corolla summer standard tire pressure recommendation is 2.3bar for the 1.6L displacement model when the tires are cold, while the 1.2T and 1.8L displacement models recommend 2.4bar cold tire pressure. These cold tire pressure values are applicable for both summer and winter tires. Tire pressure is related to seasons: Tire pressure is safe within a certain floating range (usually 10%) of the factory calibration value. For current civilian car tires, the generally acceptable safe tire pressure range is between 2.0-2.8bar. In winter, the tire pressure should be based on the standard tire pressure of the car tires, with an appropriate increase of about 0.2bar. In summer, it should be about 0.1bar lower than the standard. These adjustments are to prevent tire blowouts. Tire pressure measurement environment: The tire pressure of cold tires and hot tires is different, with a difference of about 0.2bar between them. Measure the tire pressure at least three hours after parking or when the tires have not been driven more than 2 kilometers. If you can only measure the tire pressure when the tires are hot, subtract approximately 0.2bar from the measured value to get the cold tire inflation pressure.
My experience with the Corolla is that tire pressure is especially critical in summer—never adjust it arbitrarily. For cold tires, the recommended range is between 30 and 33 PSI, as indicated on the door frame label or the owner’s manual. Tire pressure naturally rises by a few PSI when driving in hot weather, so checking it when the tires are cold is the safest approach. Low tire pressure leads to faster wear and higher fuel consumption, while excessive pressure increases the risk of a blowout, especially at highway speeds. I make it a habit to check the pressure with a gauge before each season change—this extends tire life and saves fuel. Given the significant temperature fluctuations in summer, I check at least once a month to ensure everything is correct.
