tire sidewall markings provide essential information about a tire’s size, performance, construction, and safety standards, helping users choose and maintain the correct tire... a typical marking such as P215/65R15 95S indicates the tire type (P for passenger vehicle), width in millimeters (215), aspect ratio or profile (65% of the width), construction type (R for radial), and rim diameter in inches (15)... the load index (95) shows the maximum weight the tire can carry, while the speed rating (S) indicates the maximum safe speed... other markings include the DOT code, which identifies the manufacturer, plant, and week and year of production for safety tracking; treadwear, traction, and temperature ratings, which describe durability and performance; and symbols such as M+S or the three-peak mountain snowflake for all-season or winter capabilities... together, these sidewall details help ensure proper fit, performance, and safe operation of the tire...
