What to Do When the Tire Has a Small Cut?

[JulianaAnn]

The solution for a small cut on the tire is to have it repaired at a professional repair shop. Car tires are one of the important components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help absorb shocks while driving, ensuring good adhesion between the wheels and the road, improving the vehicle's traction, braking, and off-road capability, as well as bearing the weight of the car. When buying tires, pay attention to: 1. Determine the appropriate tire type for your car; 2. Know the tire size, usually marked on the side of the tire; 3. Check if the purchased tire is a retreaded one and note the production date of the tire.

As a veteran driver who frequently takes long-distance trips, I can't stress enough how important it is to not overlook minor tire damage. Last month, my front right tire had a small cut that I thought was nothing, but it ended up bulging while I was driving on the highway. The location of the damage is crucial—scratches on the tread's surface rubber are no big deal, but if the cord fabric is exposed or the sidewall is damaged, you must replace the tire. When using a coin to measure tread wear in the grooves, also check the depth of any cuts; anything over 2mm is very dangerous. Tire sealant is only suitable for puncture wounds—never apply it haphazardly to cuts. A small tip: if you encounter a similar situation, don't take risks like I did. A tire shop can remove the tire, spray it with soapy water, and easily check for leaks.

My best friend scraped the curb while reversing last week and got really anxious about a chunk of rubber torn off the tire sidewall. The sidewall is the most vulnerable part of a tire, with only a single layer of rubberized cord fabric—any damage there can easily lead to bulging or blowouts. She immediately used her phone flashlight to inspect it for ten minutes: if you can see the grid-like cord fabric, the tire must be replaced immediately. For dark cracks, press them to test elasticity. From my experience, minor rubber wear might be tolerable for city driving, but avoid highways and heavy loads. Rear tires have slightly higher fault tolerance than front tires—you can temporarily move a damaged tire to the rear in an emergency, but a professional inspection is still necessary. Rubber aging is also critical; tires over five years old should be replaced for safety.

When I first got into car modifications, I didn't know much and thought peeling tires were just normal wear and tear. There's a saying in the modding community: sidewall damage equals a ticking time bomb. Especially for low-profile tires with an aspect ratio below 45 - any sidewall damage means immediate replacement. Last time, my Nankang NS-20 tires had a chunk of rubber scraped off after just 3,000 km. A water leak test at the tire shop revealed hairline cracks. Actually, tire rubber has a layered structure - surface damage isn't the main concern, but compromising the inner cord layer causing deformation is dangerous. Always check for scratches near the wheel rim edges during car washes, as that area most commonly causes secondary tire damage.

Last time I changed tires, the technician shared an interesting tip: The biggest fear after tire surface damage is getting small stones embedded. Sand particles act like a file, continuously grinding the wound during driving. My handling experience involves three steps: Use a stiff brush to clean debris from the wound, assess depth by touch, and finally apply tire protection wax to seal out moisture. Be especially cautious of cuts deeper than the thickness of a 1-yuan coin, particularly V-shaped wounds in the shoulder transition area which are prone to tearing. Keeping tire repair sealant for emergencies is fine, but note it only fills holes and can actually corrode the casing fabric on surface damage. Also pay attention to the tire's age – tires over six years old with even minor surface damage should be retired.
