overinflation is good. Underinflated

enough air, can result in:
:
Tire overloading and overheating,
which could lead to a blowout
Premature or irregular wear
Poor handling
Reduced fuel economy for

vehicles
Reduced range for electric vehicles
Overinflated tires, or tires that have
too much air, can result in:
Unusual wear
Poor handling
Rough ride
Needless damage from road
hazards
