The first number, 185, represents the tire width of 185MM. 65 indicates the aspect ratio of the tire section is 65%, meaning the section height is 65% of the width. The letter R stands for radial tire, and 15 represents the rim diameter of 15 inches. The Buick Excelle has a maximum speed of 170km/h and a fuel consumption of 4.7L per 100km.

I remember last year when I took my Buick Excelle to change tires, the mechanic immediately pointed out that the original factory tires are usually 195/65 R15 or 195/55 R16, depending on the model year. For example, older models before 2010 mostly used 195/65 R15, while newer models might have been upgraded to 16-inch. These specifications mean the tire width is 195 millimeters, the height is 65% of the width, and the tire diameter is 15 inches. When changing tires, it's essential to match the manufacturer's recommendations to maintain stable steering and braking. From my own experience, if you accidentally install the wrong size, fuel consumption will increase, and it's easier to skid in rainy weather. So, I recommend everyone to regularly check the label on the door edge or the vehicle manual, where the accurate model information is indicated. When replacing, consider well-known brands like Michelin or Continental for longer lifespan. Generally, tires should be replaced every 5 years or when the tread wears down to the safety line. Don't compromise safety to save a little money.

What lights should be turned on when a motor vehicle is temporarily parked at night?

When a motor vehicle is temporarily parked at night, it should turn on the hazard warning flashers, clearance lights, and rear position lights to alert other vehicles. Prepare for night driving by checking whether the lighting signal lamps of the vehicle are in good condition and effective before departure. For long-distance driving, proactively ask others about the road conditions along the route. Traffic regulations stipulate that vehicles traveling in the same direction at night are not allowed to use high beams. If the vehicle ahead encounters high beams from the rear, the rearview mirror inside the front vehicle will reflect the light. To avoid glare, adjust the angle of the rearview mirror to reduce the dazzling effect.

What does the automatic transmission P button mean?

Automatic transmission P button refers to the parking gear, where P is the abbreviation. After parking, you need to engage the P gear to prevent the vehicle from rolling, especially when parking on a slope. The general method to engage P gear is to press the brake pedal and wait until the vehicle comes to a complete stop before shifting or using the electronic button for models equipped with it. Additionally, due to the different structure of the automatic transmission, it is strictly prohibited to shift into P or N gear while driving. Once engaged, it can cause severe damage or even total failure of the automatic transmission, leading to significant losses. Therefore, drivers must be very careful when operating it.
