Does Automatic Tire Repair Fluid Damage Tires?
2 Answers
Automatic tire repair fluid can indeed damage tires. This fluid is a synthetic polymer compound that chemically reacts with the inner rubber of the tire and the wheel hub, leading to corrosion of both the tire and hub. Additionally, automatic tire repair fluid can negatively affect vehicle stability. Normally, tires require even mass distribution for proper operation, but when this fluid is injected into the tire, it may only adhere to one side of the tire wall, disrupting the tire's balance. Reasons to avoid using automatic tire repair fluid include: 1. It cannot repair excessively large punctures; 2. It is ineffective for sidewall punctures; 3. It is incompatible with vehicles equipped with tire pressure monitoring systems; 4. Caution is advised when used in extremely low temperatures or at high altitudes.
I've been driving for over a decade and have used tire repair sealant several times. For instance, during a long trip when my tire got punctured by a nail, I quickly sprayed it on to stop the leak – it worked well enough to get me to a service station. But the trouble came later. Once dried, that stuff clogs up the inside, requiring chemical cleaners for removal. The mechanic told me it corrodes rubber and rims, accelerates tire wear, and affects wheel balance – I could feel the steering wheel shaking while driving. It's a lifesaver in emergencies, but the damage is real. Now I keep a spare tire in my car to avoid long-term reliance. Safety first! Professional post-emergency treatment saves money in the long run – a bottle costs tens of yuan, while repair fees may exceed hundreds, which is a huge loss. My advice: use it strictly for emergencies, then get immediate professional inspection to protect tire lifespan.
