Dunlop Sport Maxx RT - 225/40R19 93Y XL MO

MFS stands for Maximum Flange Shield. It is a protective rubber profile that runs around the circumference of the tire above the flange to help protect the wheel rim from curb damage.

The Sport Maxx RT is a summer performance tire. It is not designed for snow or ice, and the rubber compound will harden in extreme cold, reducing grip.

The MO marking indicates that the tire has been approved by Mercedes-Benz, signifying it meets the specific performance and quality standards set by the vehicle manufacturer.

While the tire features motorsports-derived technology, it is primarily a high-performance street tire. It can handle spirited driving, but specialized track tires are recommended for intensive racing use.

It is generally recommended to rotate tires every 5,000 to 7,000 miles to ensure even tread wear, though you should check your vehicle manual for specific intervals.

XL stands for Extra Load. It indicates that the tire has a reinforced construction capable of carrying a higher load capacity than a standard tire of the same size.

Check tire pressure levels and ensure your vehicle's wheel alignment is within specification.

Have a professional technician check your vehicle's alignment and suspension components.

The tires likely need to be re-balanced; visit a tire service center to ensure the wheel-tire assembly is perfectly balanced.
