Does a small tear in the tire need to be replaced?

[DiXavier]

Tire with a small tear needs to be assessed based on the location of the tear. If it's on the tread and there's no air leakage, it can continue to be used normally without replacement. If there is air leakage, it should be repaired before further use. If the tear is on the tire sidewall, check if the cord ply is damaged. If the cord ply is intact, short-distance driving in the city is possible. If the cord ply is damaged, the tire should be replaced immediately. Below are the handling methods for a damaged car tire: 1. If the tire is damaged while driving: Pull over immediately to inspect the tire. If the tire pressure drops rapidly, do not continue driving; replace it with the spare tire and drive to the nearest repair shop. 2. If the air leakage is slow, use a car air pump to replenish the tire pressure, then drive at low speed to a repair shop. Never continue using the tire with severely low pressure as it poses significant safety risks, can further damage the tire, and may even harm the wheel rim.

Last time my tire got a chunk peeled off, I went to several shops for advice. The key to tire damage lies in the location and depth. If the sidewall is damaged, even a small piece needs replacement because it's the thinnest part—once the cords break, it's prone to bulging. For the tread, test the depth with your fingernail; if the white cords aren’t exposed, it might still be usable. However, you should check the damaged spot daily and keep an eye on it during car washes. If you notice cracks lengthening or bubbling, replace the tire immediately. A sudden blowout on the highway is no joke—my neighbor learned this the hard way, spending over ten grand on repairs. Also, if the tire is over five years old, it’s safer to just condemn it outright for such damage.

After driving a taxi for ten years, the tires I've replaced could fill a warehouse. Tire surface damage depends on the situation: superficial tread damage like being chipped by a stone can be patched and still run for thousands of kilometers. But sidewall damage? Change it immediately! The sidewall is like an eggshell; damage to the cord layer is like a ticking time bomb. Once during a night shift with passengers, I ignored a sidewall cut, and suddenly there was a loud 'bang'—the steering went out of control. Checking the surveillance later, it was all because of a fingernail-sized cut. Now I teach my apprentices: after spotting damage, first use a phone flashlight to check the interior—if you see a grid pattern, stop driving immediately. Then press around the wound with your finger; if it feels soft, it means the cords are broken. Don't hesitate to spend a few hundred bucks—a blowout repair could cost you ten new tires.

With two decades of experience in the repair shop, I've handled countless cases of tire damage. Three golden rules: location, depth, and shape. Sidewall damage over 3mm deep must be replaced; tread damage can still be saved as long as the cords aren't exposed; jagged tears are ten times more dangerous than smooth ones. Last week, a car owner hesitated to replace a damaged tire, resulting in a tear on the highway that even deformed the wheel rim. Here's my advice: apply soapy water to the damaged area—if bubbles form, it's leaking and needs replacement; if not, monitor tire pressure regularly and inspect immediately if it suddenly drops by 0.2 or more. Any damage on tires older than five years should be discarded outright, as aged rubber can't withstand secondary damage.

Three generations of my family have been off-roading, and we've blown eight tires in the Gobi Desert. When a tire gets a cut, you must play detective: First, check the wound location. Cuts on the tire shoulder are the most treacherous—this area bends frequently, and a small nick can turn into a major split in just two weeks. Next, measure the depth—if a key tip can penetrate more than 5mm, the cords are definitely exposed. Third, consider the tire's age—for tires over 60,000 km, any cut is a death sentence. Once, while crossing a no-man's-land, we ignored a tread cut, and three days later, the whole tire split open like a banana peel. Now, our team's rule is: If a cut is found, seal it temporarily with hot vulcanizing cement, and replace the tire immediately upon return. After all, wilderness rescue costs can buy half a car.

Car enthusiasts often face tire troubles when modifying their vehicles. Assessing structural damage is crucial when the tire's surface is scratched: minor rubber abrasions on the outermost layer are harmless, but exposing the white cords is a fatal flaw. I once had a set of performance tires where a 2 cm cut from a metal fragment just reached the cord layer; a professional internal patch at a specialized shop saved them. However, the sidewall is different—it only has a single layer of cords, so any damage here is like puncturing a water bag. At a track day last year, I witnessed something even scarier: a rice-sized abrasion on the sidewall caused the tire to burst like a balloon at 160 km/h. For regular car owners, I recommend replacing the tire if the damage exceeds the size of a coin. Modified car owners should be even more cautious, as their tires endure far greater pressure than standard ones.
