Volvo 2005 V70 - Manual (Page 79)

If this occurs, reduce vehicle speed to a maximum of 50 mph (80 km/h). The vehicle can be driven approximately 50
miles (80 km), or somewhat farther if the vehicle is not heavily loaded. The tire should be replaced as soon as
possible.
Hard braking and sudden steering maneuvers should be avoided.
In certain cases, it may be difficult to see which self supporting run flat tire is defective. To determine which tire is
damaged, check the inflation pressure of all four tires.
WARNING!
• Only specially trained persons should mount self supporting run flat tires.
• If self supporting run flat tires are mounted, the vehicle must be equipped with a Tire Pressure Monitoring System.
• After a low pressure warning has been displayed, do not exceed 50 mph (80 km/h).
• Avoid severe cornering and hard braking, and minimize the distance traveled before replacing the self supporting
run flat tire.
• Self supporting run flat tires cannot be repaired. They must be replaced if damaged or punctured.

Tire designations
Federal law mandates that tire manufacturers place standardized information on the sidewall of all tires (see the
illustration).
The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a tire designation):
1. 215: the width of the tire (in millimeters) from sidewall edge to sidewall edge. The larger the number, the wider the
tire.
2. 65: The ratio of the tire's height to its width.
3. R: Radial tire.
4. 15: The diameter of the wheel rim (in inches).
5. 95: The tire's load index. In this example, a load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maximum speed at which the tire is designed to be driven for extended periods of
