A tire pump is a tool used in vehicle mechanics.
A tire pump is used to inflate the tires of a vehicle. Tires have a maximum tire pressure of 40 and will not increase beyond this. This does not require the player to have read any recipe magazines and can therefore be performed on any vehicle type.
To inflate a tire, open the Vehicle Mechanics menu and right-click on the wheel in question. Note that tires can be overfilled, and the current/max pressure will be shown in the upper right. Move or choose to inflate the next tire to cancel the inflation.
The tire pump is not required to deflate a tire.
Tire pumps can be found in gas stations, sheds, garages, mechanic, storage units and crates,
Can be found in the trunk of vehicles.
