Take some and check your vehicle’s tires
#1: Tire Pressure: For most vehicles, tire pressure ranges from 32psi to 80psi (Pounds per Square Inch). But, read your tire’s sidewall, and it will specify what it requires for tire pressure.
#2: Tread: Tread is important, because, if no tread, no traction; and if there’s no traction you will not have the ability to control your vehicle in an emergency or, just normal driving.
#3: To help warn you that your tires have reached that point wear bars are moled into your tires which run across their tread pattern from their outside shoulder to inside shoulder.
