These numbers tell you the type and size of the tire. The series always begins with a letter:
P means passenger tire
LT means light truck tire
The following three numbers are the section width—the width of the tread on the tire. Two numbers after the slash represent the tire aspect ratio, meaning the sidewall height is expressed as a percentage of the section width. The final number after the R is the tire’s diameter in inches.
Here’s an example. P225/60R16 means:
It is a passenger tire
Section width = 225mm
Aspect ratio = 60% of 225mm (the sidewall height would be 135mm)
Rim diameter = 16 inches
