Find out your vehicle's tire size:

• Find your size on your tire: A tire's sidewall is simply the outer and inner "walls" on the sides of a tire. Every sidewall has its own unique information.
  
  
• Find the information in your vehicle owner's manual in the glove compartment or on the tire information sticker on your driver's side door.
  
  
• Usually those elements contain all the information related to your tire size and specifications as well as the appropriate tire pressure.
