The part or number before the slash represents the total width of the tire. This must be fitting to the width of the rim upon which the tire is to be installed.
The middle number, in this case, 45, represents the height of the sidewall expressed as a percentage of the width while the third part with the preceding ‘R’ represents the diameter of the wheel recommended for the tire size.
