Kustone Passion P9S RunFlat 315/30 R22 107W XL

RunFlat technology allows you to continue driving for a limited distance and at a reduced speed (typically up to 80 km/h or 50 mph for about 80 km or 50 miles) even after the tire has lost all air pressure due to a puncture. This provides safety and convenience, allowing you to reach a safe location.

While some RunFlat tires can be repaired, it depends on the type of damage and the manufacturer's recommendations. Repairs should only be performed by experienced tire technicians. Often, if the tire has been driven on significantly after losing pressure, replacement is recommended for safety.

RunFlat tires are designed to work with standard wheel rims. However, it is crucial that the tires are mounted by a professional who understands the specific requirements for fitting RunFlat tires.

The primary difference is the reinforced sidewall construction of RunFlat tires, which supports the vehicle's weight without air pressure. This construction typically results in a firmer ride and can make the tire heavier than its standard counterpart.

'XL' stands for Extra Load. It indicates that the tire has a higher load-carrying capacity than a standard tire of the same size. This is common on performance tires for heavier vehicles.

The driving distance and speed limitations vary by manufacturer and tire model. For the Kustone Passion P9S, it's generally advised to drive no more than 80 km (50 miles) at speeds not exceeding 80 km/h (50 mph) after a puncture. Always check the specific recommendations for your tire.

This can be a characteristic of RunFlat tires due to their reinforced sidewalls. Ensure tires are properly inflated to the vehicle manufacturer's recommended PSI. If the issue persists, consult a tire professional.

Ensure the TPMS sensors were properly reset after installation. Re-sync the TPMS system according to your vehicle's manual instructions. If the problem continues, have the TPMS sensors checked by a technician.

This may indicate an imbalance or alignment issue. Have the tires balanced and the vehicle's alignment checked by a professional tire service center.

Ensure you are adhering to the speed and distance limitations for RunFlat tires (typically max 80 km/h or 50 mph for up to 80 km or 50 miles, but check specific product guidelines). Drive directly to a safe location or repair facility.
