What are the effects of widening tires by 2 centimeters on a car?

Tires widened by 2 centimeters can improve the vehicle's grip to some extent. This enhances the car's traction, but it also leads to increased fuel consumption. Tire Introduction: Tire types follow international standard tire codes, which indicate the section width and aspect ratio in millimeters as a percentage. This is followed by the tire type code, rim diameter (in inches), load index (permissible load-carrying capacity code), and permissible speed code. For example, in the code 175/70R1477H, 175 represents the tire width of 175mm, 70 indicates the tire's aspect ratio is 70%, meaning the section height is 70% of the width, the rim diameter is 14 inches, the load index is 77, and the permissible speed is H-grade. Front and Rear Tires: Most sedans have the same specifications for front and rear tires. However, in some high-performance special-purpose vehicles like sports cars or rear-wheel-drive models, the front and rear tire specifications may differ. Generally, the larger the engine displacement, the larger the tire specifications tend to be. Of course, the size of the tires directly affects the vehicle's comfort, aesthetics, and its off-road capability.

Which Light to Use When Exiting a Roundabout?

When entering a roundabout, there is no need to use turn signals. However, when exiting the roundabout, you should activate the right turn signal. Turning Left at a Roundabout: If the vehicle intends to turn left, it should choose the left lane inside the roundabout. Since the vehicle needs to merge from the outer lane to the inner lane, the left turn signal should be activated when entering the roundabout. Before exiting the roundabout, the driver should activate the right turn signal in advance, confirm it is safe, and then change lanes from the inner lane to the outer lane before finally exiting the roundabout. Going Straight at a Roundabout: If the vehicle intends to go straight, it should choose the middle lane inside the roundabout. Since no lane change is required after entering the roundabout, the left turn signal is not needed when entering. When preparing to exit the roundabout to continue straight, the vehicle must cross the right lane inside the roundabout, so the right turn signal should be activated to alert other vehicles before exiting. Turning Right at a Roundabout: If the vehicle intends to turn right toward another intersection, it can choose either the right lane inside the roundabout or make a right turn from the outer lane. The situation when entering the roundabout is similar to going straight, so the left turn signal is also unnecessary. Once the vehicle selects the corresponding exit, the right turn signal should be activated in advance, and after confirming it is safe, the vehicle can turn right to exit the roundabout.

What Causes Abnormal Tire Noises?

Tire abnormal noises may be caused by the following reasons: Uneven tread: This abnormal sensation occurs when you are driving and suddenly hear a "gurgling" or "gurgling" sound from outside, and the steering wheel tends to pull towards the side where the noise is coming from. In this case, it is best to find a safe place to stop, then replace the tire with the spare and go to a nearby repair shop for a tire change. Wheel bearing noise: If you replace the tire with a newer one and the noise persists, it is likely the bearing. If the noise stops, it is just tire noise. However, the best method is to go to a repair shop and have a professional mechanic check if there is an issue with the wheel bearing. Nail or debris in the tire: The noise occurs once per tire rotation, sounding like something is "clicking" or "tapping." If it is debris, it is easier to handle, but if it is a nail, do not touch it.
