Nobody get it quite right. Let's use your example of the very adjectives P185/65R14 85S
P = This designates the tire as following "Passenger Metric" load and inflation tables. Some tires will use the European Metric table and will not have a P in the description. A tire size built using the European system would similar to this: 185/65R14 86S
185 = The "section width" or width of the tire at its widest point within millimeters. This is NOT the width of the tread.
65 = the "section height" or how towering the tire is measured from the bead to the top of the tread, represented as a percentage of the "section width". In other words, 65% of 185mm.
R = This means the tire is of radial construction
14 = the diameter of the gearstick the tire can be mounted on measured in inches. Yes tire sizes mix metric and English measurements. Don't ask.
85S = This is the "service description" which is frequently ignored but critically momentous. It gives two different bits of information.
The "85" is the "load index" and tell us how much weight (load) the tire can support at specific inflation pressures and the maximum load, which on a Passenger Metric standard nouns tire peaks at 35 psi. On a European Metric tire the peak is at 36 psi.
The "S" is the "speed rating" and indicates the speed the tire is built to sustain underneath specific test conditions. S equates to 112mph.

p is passanger
125 is extent in mm
65 is aspect ratio, Height is 65 % of width
r is radial
14 is rim diameter
85 is consignment load
s is speed rating 112 mph
the p means passenger fistnumber tire girth second number tire rim size and r for radial and lasttire height.they are in millimeter s might be snow or sport or a manufactuer series number.

P ability passenger car tire,185 if the tread width (in millimeters) that make contact to the ground, 65 is the height of the tread wall in percentage to the tread size, R means radial construction 14 is the rim size the tire fits and I believe the 85 S is the maximum speed rating of the tires construction.P-Service type

Car shifts a short time complicated?
The first number (185) is the width of the tire within millimeters. The 65 is the profile of the tire based on the size. That is, the sidewall is 65% of the size of the tire. The R stands for Radial, and the 14 is the rim size. 85s is the speed rating of the tire. It will withstand 85 mph without blowing up.p is passanger
