What are the symptoms of tire out-of-roundness?

The symptoms of tire out-of-roundness include: 1. The vehicle pulls to one side while driving; 2. The car body and steering wheel vibrate. The functions of tires are: 1. To support the entire weight of the vehicle and bear the load of the car; 2. To transmit traction and braking torque, ensuring the adhesion between the wheels and the road surface; 3. To reduce and absorb vibrations and impacts during driving, preventing severe vibrations and early damage to car components; 4. To adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency. Tires are circular elastic rubber products installed on metal rims, designed to roll on the ground for various vehicles or machinery. They support the car body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance.
When I'm driving and the tire is out of round, the most obvious symptom is the steering wheel shaking like a phone vibration. Normally, when driving above 60 km/h, the entire driver's seat shakes, especially when holding the steering wheel—my fingers even go numb from the vibration. Once on the highway, when the speed exceeded 80 km/h, it felt like the whole car was doing a swing dance, with stuff in the trunk rattling loudly. I took it to the repair shop, and sure enough, the right front tire was out of round. The mechanic said this kind of shaking would get worse over time and cause uneven tire wear, with the edges wearing down completely. Now, I'm extra careful going over speed bumps, worried about knocking another tire out of round. Additionally, the braking distance increases, and it's easier to skid in the rain, posing significant safety risks. It's recommended to get it checked as soon as you notice the shaking.
