Yokohama DB Decibel E70

Tyre sizes are typically written like this: 225/55R18 98V
Here’s what each part means:

• 225 – Tyre width in millimeters

• 55 – Aspect ratio (height as a % of width)

• R – Radial construction

• 18 – Diameter of the wheel in inches

• 98 – Load index (how much weight the tyre can carry)

• V – Speed rating (maximum speed capability)

1. Maintain Proper Tyre Pressure

• Check your tyre pressure at least once a month and before long trips.

• Inflate to the manufacturer’s recommended pressure (found in your vehicle's manual or on the driver-side door frame).

• Incorrect pressure can affect handling, fuel efficiency, and wear.

 

2. Rotate Tyres Regularly

• Rotate your tyres every 8,000 to 10,000 km (or every 6 months) to ensure even tread wear.

• Use the rotation pattern recommended by your vehicle manufacturer.

 

3. Balance and Align Wheels

• Have your wheels balanced and aligned at least once a year or if you notice uneven wear, vibrations, or pulling to one side.

• Proper alignment ensures better handling and longer tyre life.

 

4. Inspect for Damage

• Regularly inspect tyres for cuts, punctures, cracks, or bulges.

• Remove any stones or debris lodged in the tread.

• If damage is found, have the tyre checked or replaced by a professional.

 

5. Clean Tyres Properly

• Clean with mild soap and water; avoid harsh chemicals that may degrade rubber.

• Ensure tyres are dry before driving to prevent slippage.

 

6. Monitor Tread Depth

• Replace tyres when tread depth reaches 2/32 inch (1.6 mm) or as advised by local regulations.

• Use a tread depth gauge or the built-in tread wear indicators.

 

7. Avoid Overloading

• Do not exceed the tyre’s load capacity. Overloading increases heat and stress, leading to potential failure.

 

8. Store Correctly (if unused)

• If not in use, store tyres in a cool, dry, and shaded place.

• Keep them upright or stacked flat (no more than 4 high), away from direct sunlight, oil, and chemicals.
