Tires with bulging sidewalls should not continue to be used. Below are the functions of tires and precautions for their use: Functions of tires: Transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the vehicle's power performance, braking performance, and passability; Work together with the vehicle suspension to cushion impacts during driving and dampen resulting vibrations. Precautions for tire use: Avoid rapid acceleration, emergency braking, or sharp turns; Avoid hitting curbs; Avoid parking on curbs; Avoid driving quickly on unpaved roads or surfaces with significant elevation differences.

A bulging tire sidewall must never be used any further, as it indicates internal ply breakage - just like a ticking time bomb that could blow out at any moment. I once accidentally hit a big pothole while driving, which caused a tire bulge. I immediately went to the repair shop to replace it, and even the mechanics said this was a major safety hazard. A tire blowout on the highway is especially dangerous, potentially causing loss of control, collisions or injuries. I recommend you stop using it immediately, switch to the spare or a new tire, while checking other tires for similar wear. Regular tire pressure checks and avoiding hitting obstacles can prevent this. Remember, safety comes first - don't gamble with your life to save a few bucks.

In my opinion, if your tire has a bulge, just replace it without hesitation—don't try to save money by continuing to use it. New tires can range from a few hundred to over a thousand yuan, but the cost of a blowout could be much worse: repair fees, towing charges, and even medical expenses could add up to tens of thousands. Once, I was helping a friend check his car—he insisted on driving with a bulging tire, and it blew out halfway, completely ruining the wheel. My advice is to use the spare tire to drive to a tire shop for an assessment. If you're on a tight budget, you can also try a reliable used tire shop. In the long run, replacing it promptly is more cost-effective and saves you the hassle of a roadside breakdown. Regularly checking tire pressure and wheel condition can help reduce this risk.

Bulging on the tire sidewall really makes it unusable, I learned this the hard way. Last year, my car had a small bulge, and I didn't take it seriously and kept driving. Within a few days, the tire blew out on the highway. Fortunately, I was driving slowly at the time, so no accident happened, but it scared me badly. The mechanic said the bulge means the internal structure is damaged and could rupture at any time. Since then, I've been avoiding potholes and checking the tire appearance every week. The safest thing is to replace the tire as soon as a bulge appears—don't take chances. Delaying it only speeds up the tire's aging process.
