How do you read a tire sidewall and choose the right tire pressure without

 title: 'How to Read a Tire Sidewall  | Big O Tires'

Reading a tire sidewall helps you understand your tire's capabilities. A typical code like 'P215/65R15 95H' indicates the tire type (P for passenger), width in millimeters (215), aspect ratio (65), radial construction (R), rim diameter (15), and service description (95H for load index and speed rating)[1][3].

Always use the pressure recommended on your vehicle's door jamb or owner's manual, not the maximum pressure listed on the tire sidewall[1][4]. The sidewall maximum is a safety limit for the tire itself, not a target for daily driving[4]. For an accurate reading, check your tire pressure when the tires are cold[6].
