Are you curious about what the different letters and numbers on your tires mean? Understanding these numbers and letters can feel overwhelming, but our team here at Jim Fisher Volvo Cars Portland in Portland, OR is here to help.

Most tires on the market will start with either a P or an LT depending on the vehicle that it's on. P stands for passenger vehicle and is the most common, whereas LT is a light truck tire. Some imported vehicles may have European tires on them and these have no letters at the beginning.

Right after the letter will be numbers that indicate the width of your tires. This will typically be a three-digit number since the width is measured in millimeters. Another number that you will want to look at is the wheel diameter. This will let you know the wheel size in inches that the tire will fit.
