Will the car pull to one side if the front tires are one new and one old? The reason is that the new tire has higher air pressure, while the old tire is slightly more worn, resulting in different grip levels between the left and right tires. The causes of vehicle pulling to one side are as follows: Different tire tread patterns: The tread patterns on the two sides are different, or one side is deeper while the other is shallower. It is best to use the same model of tires for the entire vehicle. At the very least, the two tires on the front axle and the two on the rear axle must be the same, and the tread depth must be identical. If they exceed the wear limit, they must be replaced. Unequal tire pressure on both sides: Unequal tire pressure will cause the tires to become different in size, inevitably leading to pulling to one side when rolling. Uneven spring deformation of the front shock absorbers: The condition of the shock absorber springs can be judged by pressing or comparing after disassembly.

Which button is for heating in the Envision's air conditioning?

Buick Envision's steering wheel heating button is located in the left-hand control area of the multifunction steering wheel, specifically the lower button of the circular button group. Method to turn on the heating: After starting the Buick Envision, wait approximately 5-10 minutes for the water temperature to reach normal operating temperature. At this point, you can activate the Envision's heating system. First, adjust the air conditioning circulation mode to internal circulation. Once set to internal circulation, the temperature inside the vehicle will gradually increase. Then switch to heating mode by pressing the button with the red arrow. The more times you press this button, the higher the interior temperature will become. Important notes for heating operation: Do not turn on the Buick Envision's air conditioning system when using heating, as the warm air utilizes the vehicle's own heat cycle to conserve energy. Activating the AC will increase fuel consumption and reduce engine power.

What tires does the Axela use?

The Axela uses Goodyear tires with a tire size of 205/60R16. The Goodyear Tire & Rubber Company was founded in 1898 and has a history of over a century. Goodyear is the world's largest tire manufacturing company, headquartered in Akron, Ohio, USA. The company primarily produces tires, engineered rubber products, and chemical products in over 90 factories across 28 countries. For the Axela's tires in daily use, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves on the tires gradually become shallower. If the tread wears flat, it will lose its drainage and anti-skid functions, significantly reducing the car's performance. Small cracks may seem minor but can be a hidden danger for tire blowouts at high speeds. Additionally, promptly remove pebbles lodged in the grooves. Try to park on flat ground. Avoid parking on roads with thick, sharp, or pointed stones. Do not park the car near or in contact with petroleum products, acids, or other materials that may cause rubber deterioration. After parking, the driver should not turn the steering wheel, as this operation accelerates tire wear. Do not splash water to cool the tires. In hot weather or during high-speed driving, tires are prone to overheating, and the tire pressure may increase. In such cases, stop to let the tires cool down. Never release air to reduce pressure or splash water to cool the tires, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent or hard braking to prevent accelerated tread wear caused by dragging between the tires and the ground.
