What to Do About Scratches on the Tire Sidewall?

3 Answers

Solutions for scratches on the tire sidewall are as follows: 1. If the scratch on the tire sidewall is not severe and has not damaged the tire's cord layer, it may not be a big issue even if left unrepaired. 2. Of course, if you're still concerned, you can go directly to an auto repair shop to patch the damaged area and redo the wheel balancing. A properly patched tire will perform almost as well as before the scratch. 3. However, if the scratch has reached the cord layer inside the sidewall, the tire should generally be scrapped immediately to avoid potential safety hazards. In summary, scratches on the tire sidewall directly impact driving safety and should never be ignored.

I just encountered this situation a few days ago—I scraped the curb while driving. Never underestimate a scratch on the tire sidewall because it's the thinnest and most vulnerable part, unlike the tread which has steel belt protection. Stop immediately to inspect the depth of the scratch. Use a coin to measure the depth of the damage. If the white cord layer inside is exposed or you feel a noticeable dent, the tire is done for and must be replaced. Even if the scratch seems shallow, stay alert for potential bulging. I recommend going straight to a professional tire shop for an assessment—don’t take shortcuts and risk driving on the highway, as a blowout is no joke. The spare tire can only serve as a temporary replacement for a few dozen kilometers. When replacing the tire, check if the rim and suspension have also been damaged.

I've been driving trucks for twenty years and seen plenty of tire issues. For sidewall scratches, the key is location and depth: the shoulder area bears the most stress and is most dangerous, while areas closer to the wheel hub are relatively safer. If you find a scratch, slow down and stop immediately. Use your phone flashlight to check for exposed white cords or cracks. If it's raining and visibility is poor, apply some saliva to the wound—bubbles will seep out if there's a bulge. Never try to patch it up with glue or tire sealant; tire patches are completely ineffective on sidewalls. Last time I had a scratch, I switched to a full-size spare and drove about a hundred kilometers, but never exceeded 50 mph. When getting new tires, remember to adjust the spare tire's pressure to the standard value—significant wear differences can cause the vehicle to pull to one side.

Is There a Specific Order Between Shifting to Neutral and Pulling the Handbrake?

Whether to shift to neutral first or pull the handbrake first depends on whether it's a manual transmission or an automatic transmission vehicle. The sequence for manual and automatic transmission vehicles: Manual transmission vehicles: Pull the handbrake first, then shift to neutral. Automatic transmission vehicles: Shift to neutral first, then pull the handbrake. Detailed steps for parking manual and automatic transmission vehicles: For manual transmission vehicles: First, press the brake pedal to slow down the car, then hold the brake to bring the vehicle to a complete stop. Pull the handbrake, shift the gear to neutral. Turn off the engine, exit the vehicle, and lock the doors. For automatic transmission vehicles: First, press the brake pedal to slow down the car, then hold the brake to bring the vehicle to a complete stop. Shift the gear to neutral, pull the handbrake, and after the car comes to a complete stop, shift to P (Park), turn off the engine, exit the vehicle, and lock the doors.

What is the 911 car?

The Porsche 911 is a sports car produced by Porsche AG of Stuttgart, Germany in 1963, designed by Ferdinand Alexander Porsche. The Porsche 911 has gone through seven generations of models, featuring unique styling and excellent durability, making it one of the legendary models and a representative of mid-rear-engine sports cars. The Porsche 911 series is divided into the Carrera series, Targa series, Turbo series, Turbo S series, and GT series. The 911 is the successor to the Porsche 356 model. The 911 replaced the previous 4-cylinder engine and was the first to feature a rear-mounted six-cylinder horizontally opposed engine. Although the 911's power output was only 130 horsepower at that time, it could still accelerate from 0 to 100 km/h in 9.1 seconds, with a top speed of 210 km/h. The 911 models from 1973 to 1989 belong to the G series, during which the displacement of the 911 models increased from 2.7L to 3.2L.

Where is the Volkswagen Bora's ESP switch located?

After starting the Volkswagen Bora, the ESP (Electronic Stability Program) system is activated by default. There is only one switch button, located at the lower left corner of the center console. Additional information: The role of the Bora's ESP in driving safety: 1. Adjusts braking force distribution to prevent the rear wheels from locking up first. It typically fails only when there is a hardware malfunction in the module; 2. Prevents wheel lock-up by calculating the vehicle's slip rate and controlling it near the peak adhesion coefficient, which is a passive safety control; 3. Traction Control System (TCS), which operates under conditions such as low-adhesion road surfaces where the drive wheels slip. The TCS requests the engine to reduce torque while lightly applying the brakes for smooth vehicle acceleration; 4. Vehicle Dynamic Control (VDC) system, which primarily corrects understeer and oversteer by actively pressurizing individual wheels. Both TCS and VDC involve active pressurization, meaning they can apply pressure to the brake lines without requiring brake pedal force.

What are the differences between the 2018 Lavida and the 2019 Lavida?

Below are the differences between the 2018 Lavida and the 2019 Lavida: 1. Difference one: Different emission standards: Most 2018 Lavida models comply with the China V emission standard; the 2019 Lavida models all meet the China VI emission standard. 2. Difference two: Exterior design: The 2019 Lavida has some new changes compared to the older model in terms of the front face, body length, width, height, and rear. 3. Difference three: Interior design: The most noticeable change is the more comfortable dashboard, featuring a brand-new center console screen and a vibrant steering wheel; the air vents are three large circular outlets, and the direction of airflow can be adjusted by turning the central switch. 4. Difference four: Safety features: Side airbags for the front and rear seats and the main airbag are only available in higher trims, but safety features such as tire pressure monitoring, ESP stability control system, seatbelt reminder, and child locks are standard across all models.

Why Does the Car Engine Sound Louder in Hot Weather?

Here are the specific reasons why the car engine sounds louder in hot weather: Poor Acceleration Performance: When pressing the accelerator, you may notice poor acceleration, lack of power, and a hysterical sound from the engine. This is most likely to occur when the engine is hot, cold, or low on oil. Dirty Gasoline: Issues such as air filter, spark plugs, ignition wires, fuel, fuel filter, carburetor, or fuel pump problems. Check if the air filter is dirty, if the spark plugs are old and need replacement, if the ignition coil is faulty, or if the gasoline is contaminated. While driving, acceleration may seem normal, and ignition might appear fine, but when maintaining a constant speed, you might notice that the engine RPM is too high while the speed doesn't increase accordingly. Try checking the coolant, oil pressure (too high or too low), the oil pressure gauge, or the ignition timing settings, as these could also cause such symptoms. Other possible causes include internal engine issues, such as a clogged EGR valve.

Why Does a Motorcycle Burn Engine Oil in Summer?

Motorcycle burning engine oil is due to the piston ring oil ring having insufficient elasticity and excessive light leakage. Insufficient elasticity and excessive light leakage: When the piston ring oil ring has insufficient elasticity and excessive light leakage, it leads to burning engine oil, which is a problem with the piston ring itself. If the gap between the valve stem and the valve guide is too large, or the valve oil seal does not seal tightly, this burning oil phenomenon is unrelated to the piston ring. Even after replacing the piston ring, the engine oil may still burn. Cylinder size deviation and excessive ovality: If the cylinder size is out of tolerance and the ovality is excessive, or if the surface has scratches or grooves, the oil ring cannot scrape off the excess oil on the cylinder wall, causing oil to enter the combustion chamber and participate in combustion. If the taper ring is installed upside down, it will scrape oil upward, also increasing oil consumption. If the piston rings are not staggered in position during assembly and are aligned in a straight line, oil consumption will sharply increase.
