How to find your tire size on the sidewall in Hamilton

Finding the exact dimensions of your rubber before shopping saves plenty of time and guesswork. Whether you drive around Hamilton Mountain, Stoney Creek, or Ancaster, knowing where to look on the rubber makes getting replacements straightforward.

Locating the numbers on the rubber

Walk out to your vehicle and look closely at the outer face of the rubber. Manufacturers stamp a long string of letters and numbers directly into the black surface during production. This sequence details the width, aspect ratio, construction type, and wheel diameter. You do not need any special tools to read this information, though wiping away brake dust or road grime first helps make the text legible.

Take a close look atulatory the sequence starting with a letter like P or the letters LT. This code tells you the intended vehicle category, such as passenger car or light truck. Following that prefix, you will see a three-digit number representing the section width in millimetres, a slash, and a two-digit profile number. Check out our Find tires by size page once you have jotted down these exact figures to see what options match your vehicle.

Reading rim diameter and load ratings

Further along that same string of characters, you will spot a letter R followed by a two-digit number. This R stands for radial construction, and the number right after it indicates the rim diameter in inches, which must match your wheels. Right beside the diameter, you will find a load index and a speed rating symbol that denote how much weight the rubber can safely support and its maximum rated speed capability.

When you need to Discount new tires for your car, bringing these exact measurements ensures you get a proper fit on the first try. Writing down the full sequence from your current tread prevents ordering mistakes and keeps your vehicle rolling safely down the road.
