Is it okay to have three tires with normal pressure and one low?

[DiMichael]

It is not acceptable to have three tires with normal pressure and one low. The tire with low pressure needs to be inspected and inflated. It is best for the tire pressure of the left and right wheels to be the same, with a small difference allowed, preferably not exceeding 0.1 bar. The biggest impact of different tire pressures on the left and right sides is that the vehicle may pull to one side, which is very dangerous. If driven under such conditions for a long time, it can also lead to uneven wear on the left and right tires. Causes of insufficient tire pressure include tire leaks, deformed rims, long-term heavy loads, and thermal expansion and contraction. If the tire pressure is insufficient, the contact area between the tire and the ground increases, friction resistance increases, steering becomes heavier, fuel consumption rises, and there may be a feeling of insufficient power. If driven for a long time with insufficient tire pressure, it can cause deformation of the tire sidewalls, accelerated aging of internal steel wires and fabric layers, reduced tire lifespan, and an increased risk of a blowout at any time.
