What is the optimal tire pressure in hot weather?

[VonWalker]

In summer, the recommended tire pressure for cars is generally between 2.2-2.4 kilopascals. Below are the precautions for tire replacement and tire maintenance: Precautions for tire replacement: Choose tires of the same specifications; replace the valve stem simultaneously; pay attention to installation direction and inflation; check tire pressure; perform a four-wheel alignment after changing tires. When removing tires, slightly loosen the fixing bolts before using a jack to partially lift the vehicle. Opt for tires with guaranteed quality. Tire maintenance: Perform four-wheel alignment and tire rotation: Conduct a four-wheel alignment and tire rotation every 10,000 kilometers. Regularly check tire pressure. When the tire tread wears down to the level of the wear indicator, the tire must be replaced. Frequently inspect tires to promptly identify issues such as bulges, cracks, cuts, punctures, valve stem rubber aging, and abnormal tire wear.
