Does a slow tire leak require patching?
2 Answers
Tires with slow leaks do require patching, but it doesn't need to be done immediately. However, you should schedule the repair as soon as possible. If left unrepaired for an extended period, more air will leak out, leading to lower tire pressure. Low tire pressure can pose safety hazards while driving. Here are the dangers of low tire pressure: 1. Low tire pressure increases tire body deformation and contact area, accelerating shoulder wear and making the tire sidewalls prone to cracking. 2. It causes increased friction (greater rolling resistance), leading to excessive heat buildup, higher fuel consumption, accelerated rubber aging, fatigue in the cord layers, and potential tire blowouts.
As a frequent driver, I believe that slow tire leaks absolutely require prompt patching—it's no trivial matter. Leaks are usually caused by small holes in the tire, such as a nail that hasn't fully penetrated or a loose valve stem leading to gradual air loss. Ignoring it can result in continuous pressure drop, increasing fuel consumption, wearing out the tire sidewalls, or even causing a sudden blowout at high speeds, leading to accidents. I recommend checking the tire pressure yourself first; if it drops too quickly, head to a professional shop immediately. Technicians will use soapy water to locate the leak—small holes can be fixed with a patch for a small cost. Major issues like sidewall damage may require a new tire. Don't skimp on this effort—safety comes first. Regularly checking tire pressure monthly can prevent many issues, and proper tire maintenance can extend their lifespan by tens of thousands of kilometers.
