What are the signs before a tire bursts?

Tire bulging is a precursor to tire blowouts. If bulging is detected, it is recommended to immediately inspect, repair, or replace the tire. Below is relevant information: The sidewall of a tire is very thin, with the carcass layer providing reinforcement to the side. Bulging or even blowouts can easily occur at damaged areas of the carcass layer, and such damage cannot be repaired. Situations where tires cannot be repaired include: severe damage to the sidewall, puncture holes in the tread exceeding 6mm in diameter, damaged or deformed bead, rubber corroded by chemicals, tire bulging, or damage from running flat. Situations where tires cannot continue to be used: 1. The tire has worn down to the tread wear indicator marks, which indicate the legal minimum groove depth of 1.6mm. Continuing to drive poses serious safety risks. 2. The tire has suffered severe damage, such as hitting a curb, falling into a pothole, or being punctured by a nail, which can cause significant harm. If the damage is on the sidewall, replacement is advised as sidewall damage cannot be repaired. 3. The tread is deformed or shows obvious cracking. In such cases, a professional repair shop should be consulted to determine whether to continue using or replace the tire.
I've been driving for over thirty years and have experienced several tire blowout risks. The key warning signs are feeling the car body unstable or slightly shaking while driving, and the steering wheel vibrating slightly, which are often caused by underinflated tires or uneven wear. Bulges on the tire surface are a big deal—they feel soft like bubbles when touched, indicating that the inner cord layers are broken, which can easily lead to a blowout at high speeds. Additionally, excessively worn tread grooves become shallow, especially when the tread wear indicators are exposed, increasing friction and the risk of heat buildup. I make it a habit to check tire pressure by pressing them manually when refueling each month and use a coin to measure tread depth for wear. When parking, I inspect around the wheel hubs for cracks or signs of air leakage—these small details can save lives. Avoid speeding and overloading to reduce high-speed friction; safe driving is the way to go for the long haul.
