Selecting the right tire size isn’t about guesswork—it’s about following the manufacturer’s specifications. Your vehicle is engineered to work with specific tire dimensions, and deviating from these can affect your speedometer accuracy, braking, and overall handling.

How to find your tire size:

• Check the sidewall: The most straightforward method is to look at the side of your current tire. You’ll see a sequence of numbers and letters, like 205/55 R16 91V.
• Check the driver’s door jamb: Most vehicles have a sticker inside the driver’s door frame that lists the original equipment (OEM) tire size and recommended inflation pressure.
• Consult your owner’s manual: Your vehicle handbook contains the manufacturer’s recommended tire specifications.

Decoding the sidewall numbers:

• 205 – Tire width in millimeters.
• 55 – Aspect ratio (the height of the sidewall as a percentage of the width).
• R – Radial construction.
• 16 – Rim diameter in inches.
• 91V – Load index and speed rating.

A critical rule: Never assume a “close enough” size will work. Replacement tires should always match the size, load index, and speed rating recommended by the vehicle manufacturer.

Part 2: Correct Tire Pressure for Different Vehicle Types

Maintaining the correct tire pressure is vital for safety, fuel efficiency, and extending the life of your tires. The ideal pressure varies significantly depending on the vehicle’s weight and purpose.

General Pressure Guidelines (PSI – Pounds per Square Inch):

Vehicle Type	Recommended Pressure (PSI)	Notes
Sedans & Family Cars	30 – 35 PSI	Balances comfort and control. Some modern sedans may specify 35–42 PSI.
Crossovers & Small SUVs	35 – 40 PSI	Higher pressure to support the extra weight. May need adjustment with passenger load.
Full-Size SUVs & Light Trucks	40 – 45 PSI	Varies significantly with payload; may increase when towing.
Electric Vehicles (EVs)	38 – 45 PSI	Often higher due to heavy batteries and to prioritize efficiency.

The Golden Rule: While these are general guidelines, always refer to the sticker on your driver’s side door jamb or your owner’s manual for the exact recommended pressure for your specific vehicle. Also, remember to check your tire pressure when the tires are “cold”—meaning the car hasn’t been driven for at least a few hours.
