Does a new car's tires need air after one year?

[SiennaDella]

A new car's tires do need air after one year. Normally used tires indeed don't require frequent inflation, but they do need regular air replenishment. Tire classification by vehicle type: Tires can be roughly classified into 8 categories based on vehicle type. Namely: PC—Passenger Car tires, LT—Light Truck tires, TB—Truck and Bus tires, AG—Agricultural Vehicle tires, OTR—Off-The-Road tires, ID—Industrial Vehicle tires, AC—Aircraft tires, MC—Motorcycle tires. Tire classification by purpose: Tires can be classified by purpose, including load-bearing tires, passenger vehicle tires, and mining tires. Load-bearing tires must indicate the ply rating in addition to the specification dimensions marked on the sidewall. However, the ply rating of load-bearing tires does not refer to the actual number of layers, but rather to the load performance of tires made with high-strength material cords, which is equivalent to the number of cotton cord layers used in the tire carcass.
