How much does Toyota tire pressure charge in summer?

According to the provisions and requirements of international standard GBT2978-2008: standard tire: 2.4-2.5 bar, reinforced tire: 2.8-2.9 bar.

In summer, when the car is parked in the open air, the air pressure can generally be lower than the standard 0. 1bar. It is most appropriate to control the tire pressure reduction at around 10% in summer. When high temperature strikes in summer, the road surface temperature rises, and the tire pressure is easy to rise. Once the tire pressure is too high, it is easy to accelerate tire wear, resulting in a puncture.

If the owner has sufficient funds, he can also fill the tires and spare tires with nitrogen. Nitrogen is an inert diatomic gas with extremely inactive chemical properties, low thermal expansion coefficient and low thermal conductivity. When the temperature changes, the degree of volume expansion is much lower than that of air, which reduces the probability of puncture. The tire filled with nitrogen has small deformation, improved grip, reduced rolling resistance and reduced fuel consumption.

Extended data:

Check the tire pressure regularly to ensure safety;

1. Observe the tire condition before going out. Radial tires, also known as low-pressure tires, are normal as long as the flatness is not too low, and they feel very elastic when stepping on the pedal. High-pressure tires are bias tires with inner tubes. From the front, the shoulder position of the tire is not prominent, which is commonly known as no cheeks. Seen from the side, the contact area with the ground is almost normal.

2. Pay attention to the friction between the tire and the ground when driving, feel the buffering force when the road surface is not very flat, and feel whether the acceleration has changed compared with usual when refueling. These are all accumulated experiences.
