What Sidewall Codes Are and How They Work

The sidewall codes are printed on the outer edge of every tire. Since these alphanumeric markings describe your tire’s size, load capacity, and speed rating, they’re essential for proper tire selection. For example, a code like P225/65R17 95H breaks down as follows:

• P stands for Passenger Vehicle.

• 225 is the tire’s width in millimeters.

• 65 is the aspect ratio, showing the height compared to the width.

• R means it’s a radial tire.

• 17 represents the wheel diameter in inches.

• 95H indicates load capacity and speed rating.
  Because these details guide installation, performance, and safety, reading them correctly ensures your tires match your car’s requirements.

Why Tire Sidewall Codes Are Important

Although small, sidewall codes provide critical safety and performance information.

• Since they tell you your tire’s proper fit, they help prevent blowouts or uneven wear.

• Because they reveal the load and speed ratings, they protect you from overloading your vehicle.

• As they identify the correct type for your driving conditions, they improve traction and comfort.

• Therefore, understanding sidewall codes keeps your car safe, efficient, and road-ready across Lancaster’s changing seasons.

How to Maintain Tires Using Sidewall Codes

Following your sidewall codes helps you care for your tires and extend their life:

• Since correct pressure ensures safety, keep your tires inflated to the recommended PSI.

• Because size affects balance, always replace tires with the same dimensions listed on the sidewall.

• As rotation prevents uneven wear, rotate your tires every 6,000–8,000 miles.

• Since seasonal driving affects tread, inspect your tires before winter and summer.

• Because professional alignment extends life, visit Meineke in Lancaster for regular tire checks.
