Product Information
Full details
The Churchill 255/30 R19 91Y is a high-performance tyre engineered for drivers who prioritize stability and responsive handling on varied road surfaces. It is ideal for performance-oriented vehicles requiring precise grip and consistent feedback, though users should note that the low-profile 30-series sidewall makes the tyre more susceptible to impact damage on poorly maintained or pothole-ridden roads.

FAQs
What do the numbers 255/30 R19 mean?
255 is the width in millimeters, 30 is the aspect ratio (sidewall height as a percentage of width), R indicates radial construction, and 19 is the rim diameter in inches.
What is the maximum speed for this tyre?
The 'Y' speed rating indicates the tyre is capable of speeds up to 300 km/h (186 mph) under proper inflation and load conditions.
Can I use these on any car with 19-inch wheels?
Not necessarily. You must ensure the 255 width is appropriate for your wheel rim width and that the load rating meets your vehicle's specifications.
How often should I check the tyre pressure?
It is recommended to check tyre pressure at least once a month and before any long road trip.
What is the significance of the 91 load index?
The 91 index means each individual tyre is rated to carry a maximum load of 615 kg (1,356 lbs).
Are these tyres suitable for winter weather?
These are performance tyres; while they offer great grip in dry and mild wet conditions, they are not specialized winter tyres and may perform poorly in snow or icy conditions.
Troubleshooting
Vehicle pulling to one side
Check tyre pressures are equal on both sides; if pressures are correct, have your vehicle's wheel alignment checked by a professional.
Increased road noise or vibration
Inspect the tyre tread for trapped debris like small stones or uneven wear patterns; check that the wheel is properly balanced.

Setup, Compatibility & Care
To ensure safety and performance, verify that your vehicle is compatible with the 255/30 R19 specification by consulting your owner's manual or checking the current tyre sidewall.
- Installation: Always have tyres installed by a professional to ensure proper bead seating and valve stem integrity.
- Pressure Management: Maintain the manufacturer's recommended tyre pressure found on the driver-side door jamb placard. Check pressures monthly, as incorrect inflation directly impacts fuel economy and tread life.
- Rotation: Rotate tyres every 5,000 to 8,000 miles to promote even wear across the set.
- Storage: If storing, keep tyres in a cool, dark, and dry place away from ozone-producing equipment and direct sunlight.
