Here's what you should do:
1. Safety First:
* Pull over immediately: Find a safe spot on the side of the road as quickly as possible.
* Turn on your hazard lights: Warn other drivers that you're stopped.
2. Identify the Cause:
* Check for Obvious Issues: Is there something blocking the tire? Is there a flat?
* Listen for Unusual Sounds: Do you hear grinding or screeching noises?
3. Take Action:
* If the cause is obvious (like a flat tire), try to fix it. If you're unsure, call for roadside assistance.
* If the cause is unclear, do not attempt to drive the car.
* Call a qualified mechanic: They can diagnose the problem and make sure your car is safe to drive again.
Possible Causes of a Locked Rear Tire:
* Brakes: A problem with your rear brakes (like a seized caliper) can cause the tire to lock up.
* Wheel Bearings: A damaged wheel bearing can cause the wheel to seize.
* Mechanical Issues: Other mechanical problems, such as a broken axle, can also lead to a locked tire.
Important:
* Never attempt to drive a car with a locked tire. This can cause serious damage to the vehicle and is extremely unsafe.
* If you suspect a problem with your brakes or wheel bearings, get it checked immediately. These problems can quickly become dangerous.
