Run-flat tires are specially designed to keep working for a limited distance even after losing air pressure from a puncture. They use reinforced sidewalls or internal support systems to help the tire maintain its shape and support the vehicle's weight. This means you can usually drive up to 50 miles at reduced speeds, giving you time to reach a safe location or service center. It's important to check your vehicle's manual for specific guidance, as performance can vary based on tire type and driving conditions.

To find out if your car can use run-flat tires, start by checking your vehicle's owner's manual or looking for a label inside the driver's door. Some vehicles are equipped with tire pressure monitoring systems (TPMS) and suspension setups designed for run-flat tires.

• If your car originally came with run-flats, it's usually best to stick with them.
• If not, consult a tire professional before switching, as not all vehicles are compatible.

Repairing a run-flat tire depends on the type and location of the damage. Some minor punctures in the tread area may be repairable, but sidewall damage or driving too far on a flat tire can make repairs unsafe.

• Always have a tire professional inspect the tire before attempting any repair.
• Many manufacturers recommend replacing run-flat tires after a puncture for safety reasons.

Run-flat tires can sometimes feel firmer than standard tires because of their reinforced construction. This may lead to a slightly stiffer ride or increased road noise, depending on your vehicle and driving conditions.

• Some drivers notice little difference, while others may feel a change in comfort.
• Advances in tire technology continue to improve ride quality for run-flat options.

Proper care can help extend the life of your run-flat tires.

1. Check tire pressure regularly, as underinflation can cause uneven wear.
2. Rotate your tires according to your vehicle's maintenance schedule.
3. Inspect for signs of damage or unusual wear patterns.
4. Have your alignment checked if you notice pulling or vibration.
