Good to know for your comfort & safety

Aspect ratio
The aspect ratio is the ratio of a tyre’s section height (H) to its section width (W).
Aspect ratio (%) = H/W x 100

Speed symbol
The speed symbol refers to the maximum speed capabilities of the tyre. It is only valid for tyres that are properly inflated and loaded within their assigned load index.

Load index
The load index is the maximum load-carrying capacity of a tyre under a specific condition.

Reinforced (Extra Load) Indication (XL-Rating)
Passenger car tyres designed for loads and inflation pressures higher than the standard version.

Tyre rotation
Tyre rotation is the regular practice of changing the position of each tyre on the car to minimize abnormal (or uneven) tread wear, which may cause:
  1. Abnormal vibration (“shimmy”)
  2. Tyre noise
  3. Decreased riding comfort
  4. Shorter tyre life
Note: We recommend that you rotate your tyres immediately if you recognize any of the above-mentioned conditions (especially on your front tyres).

Tread Wear Indicator
Triangle marks ( ▲ ) on the sidewall show the tread groove position  of the “tread wear indicators”, the “tread wear indicators” represent 1.6mm of remaining tread depth at which time the tyre should be replaced.

How to read the tyre code:

7) "RADIAL" Designation --- The word "RADIAL" must be branded on a tubeless type tyre.

8) "TUBELESS" Designation The word "TUBELESS" must be branded on a tubeless radial ply tyre.

9) YOKOHAMA tyres are marked in accordance with international regulations. So the sidewall is marked with a circle containing an E and the number of the country of homologation. This marking is followed by a multi-digit homologation number. e.g. E4 1234567*987654 S2WR2 (4 = Netherlands)

10) DOT Mark --- The symbol certifying compliance with FFVSS respectively.

11) BluEarth Mark --- The symbol of YOKOHAMA´s eco tyre showing YOKOHAMA´s commitment to producing environmentally, human and socially friendly tyres.
