Do Tires Need to Be Replaced If the Grooves Are Cracked?

Tire groove cracking indicates that the tire has aged and can no longer be used, requiring immediate replacement. Precautions for replacing tires: Choose the right tire: The specifications of the tire must match those of the other tire on the same axle. Replace the valve stem as well: After replacing the tire, the aging cycles of the new tire and the valve stem differ. During the new tire's cycle, the valve stem may develop issues. New tires are best installed on the rear axle of the vehicle: If more worn tires are placed on the rear axle, it reduces the rear wheels' water drainage capability, thereby increasing the risk of driving in rainy conditions. Tires should not be used further under the following circumstances: The tire is already worn. Tires have tread wear indicators with a height of 1.6 mm (the legal minimum groove depth). Using worn tires on wet roads can lead to "hydroplaning," increasing the risk of losing control. The tire is damaged. Hitting curbs, falling into potholes, or punctures from nails can severely damage tires. Damaged tires may be repairable, but only a professional repair shop can accurately determine whether the tire can be repaired or needs to be replaced. The tire has aged. If tread deformation or significant cracking is observed, stop using these tires immediately and have them inspected by a professional repair shop to determine if they can still be used. The tire has a bulge. Tire bulges are a high-risk factor for blowouts, especially on highways. Tires with bulges should be replaced promptly.

Can the steering wheel be turned when the handbrake is engaged?

The steering wheel can be turned when the handbrake is engaged. Handbrake usage precautions: Parking on slopes and engaging the handbrake for extended periods: It is well known that the handbrake must be engaged when parking on a slope. However, if parking for an extended period, avoid leaving the handbrake engaged continuously. Keeping the handbrake engaged on a slope can cause significant damage, as the slope increases the braking force required, accelerating wear. The correct approach is to first secure the vehicle with the handbrake, then place bricks or other objects under the tires before releasing the handbrake. Re-engage the handbrake to distribute the load between the wheels and the handbrake. Alternatively, you can leave the car in first gear or reverse. Steering wheel handling techniques: Place both hands firmly on the left and right edges of the steering wheel. Grip naturally with your fingers curled inward and thumbs extended along the wheel's edge, avoiding bending them inward. This grip positions the right hand closer to other controls for easier operation. Additionally, when the right hand operates other controls, the left hand can still effectively steer.
