Extended Product Information
FAQs
What does the XL marking stand for?
XL stands for Extra Load, indicating that the tire is reinforced to carry a heavier load than a standard load tire of the same size.
What do the numbers 255/40 R18 mean?
255 is the width in millimeters, 40 is the aspect ratio (sidewall height), R indicates radial construction, and 18 is the rim diameter in inches.
Can I use these in the snow?
The FM601 is designed for general passenger use; while it handles light weather, it is not a dedicated winter tire and should be used with caution in heavy snow or ice.
How often should I check my tire pressure?
It is recommended to check your tire pressure at least once a month and before every long road trip.
Is this a directional tire?
Always check the sidewall markings upon installation; if arrows are present, the tire must be mounted to rotate in the direction indicated.
What is the 99Y speed rating?
The 99 is the load index, and Y indicates the tire is capable of sustained speeds up to 186 mph (300 km/h) under optimal conditions.
Troubleshooting
Vehicle pulling to one side
Check tire pressure in all four tires and verify wheel alignment with a professional technician.
Increased road noise or vibration
Inspect for uneven tread wear patterns and ensure the tires are properly balanced and rotated.
TPMS light remains illuminated
Verify that all tires are inflated to the manufacturer-recommended pressure; if the light persists, have the sensor inspected.

Setup, Compatibility & Care
To ensure maximum safety and performance, always have the Kpatos FM601 installed by a certified professional using calibrated mounting equipment. Before driving, verify that the tire pressure is set to the specific PSI requirements found on your vehicle's driver-side door jamb, not the maximum pressure listed on the tire sidewall. Compatibility is limited to vehicles requiring the 255/40 R18 size; using this tire on mismatched rim widths may result in uneven wear. For maintenance, rotate your tires every 5,000 to 7,000 miles to promote even tread wear and perform visual inspections for sidewall damage or foreign objects embedded in the tread after long trips.
