Understanding Tyre Sizes: The Basics

Tyres are the unsung heroes of your vehicle: the right tyre is crucial for safety, efficiency, and performance. Each tyre has a unique size code, usually a mix of numbers and letters, that indicates its exact specifications. Understanding this code is essential, especially when it comes time to replace or upgrade your tyres.

Locating the Tyre Size Information

The easiest way to find your tyre size is to look at the sidewall of your current tyres. Here, you’ll find a series of numbers and letters. For example, a tyre marked “215/60R16 95H” reveals everything from its width to its load capacity. If the sidewall is unclear, the next best place is your vehicle’s owner’s manual. Many cars also have a tyre information sticker located on the inside of the driver’s door jamb, providing the same details.

Decoding the Numbers and Letters

Each segment of the tyre code means something specific:

  • 215: Tyre width in millimetres.
  • 60: Aspect ratio (height to width).
  • R: Radial construction.
  • 16: Diameter of the wheel in inches that the tyre fits.
  • 95: Load index (how much weight the tyre can support).
  • H: Speed rating (maximum speed the tyre can safely maintain).

Tyre Size Variations for Different Vehicle Types

Different vehicles require different tyre sizes for optimal performance. Here’s a quick guide:

Vehicle Type    Common Tyre Sizes
Sedan 205/55R16, 195/65R15
SUV 225/65R17, 235/60R18
4×4 255/70R16, 265/70R17
Van 195/75R16, 215/70R15


Staggered Tyre Sizing

Some vehicles, especially performance cars, use staggered tyre sizing, where the rear tyres are larger than the front ones. This setup enhances handling and traction, but can also be chosen for its visual appeal. For example, a car might have 245/40R18 tyres at the front and 275/35R18 at the rear. The rear width enables a better transfer of power and grip for RWD vehicles, while the thinner front tyres ensure maximum control when steering. Some people opt for thicker rear tyres to give their vehicles a more aggressive, sporty stance from behind.
