Car normal RPM range: Generally, a car's RPM ranges between 1000-3500, with maximum torque output occurring around 3000 RPM, after which it becomes inversely proportional to RPM. Below is relevant information about car RPM: 1. Typical engine idling speed is 1000 RPM, increasing to 1500 RPM after starting. Shift to 2nd gear when speed doesn't exceed 15 km/h, with subsequent upshifts generally occurring at 2000 RPM until reaching top gear. High-performance engines may tolerate an additional 500 RPM. During normal driving, RPM in any gear should generally not fall below 1500 or exceed 2500. When exceeding this range, timely downshifting or upshifting is required. 2. For regular driving, maintaining around 3000 RPM is usually sufficient. Higher engine RPM means more work per unit time, thus greater power output. However, excessive RPM accelerates the combustion cycle, causing incomplete fuel combustion before exhaust, resulting in exponentially increased fuel consumption. Therefore, higher RPM isn't always better. Appropriate RPM mainly depends on vehicle speed and gear selection.

The age requirement for applying for an A1 driver's license is between 26 and 50 years old. Other requirements are as follows: Height must be at least 155 cm; visual acuity must be at least 5.0 on the logarithmic visual acuity chart (either naked or corrected vision); no red-green color blindness; ability to distinguish the direction of sound sources with each ear at a distance of 50 cm from a tuning fork; both thumbs must be intact, and each hand must have at least three other fingers intact with normal movement function; both lower limbs must be intact with normal movement function, with a length difference not exceeding 5 cm and no movement dysfunction. An A1 driver's license can only be obtained through license upgrading and cannot be applied for initially like a C1 or B2 license. The most common path is to start with a C1 license, then upgrade to an A3, B1, or B2 license before upgrading to an A1 license. Applicants must have held an A3, B1, or B2 license for at least five years and must not have accumulated 12 penalty points in the current scoring cycle or the last five consecutive scoring cycles to upgrade to an A1 license. For those upgrading from an A2 license to an A1 license, the requirements are: having held the A2 license for at least two years and not having accumulated 12 penalty points in the previous scoring cycle. According to Article 12 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," applicants must meet the following requirements: For small cars, small automatic transmission cars, small automatic transmission cars for the disabled, and light motorcycles, the age requirement is between 18 and 70 years old. For low-speed trucks, three-wheeled vehicles, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, or wheeled self-propelled machinery, the age requirement is between 18 and 60 years old. For city buses, large trucks, trolleybuses, or trams, the age requirement is between 20 and 50 years old. For medium-sized buses, the age requirement is between 21 and 50 years old. For tractor-trailers, the age requirement is between 24 and 50 years old. Students undergoing full-time driving vocational education who apply for large buses or tractor-trailers must be between 20 and 50 years old. The permitted vehicle types for an A1 license include: large buses with a capacity of 20 or more passengers, as well as passenger vehicles with a body length exceeding 6 meters. Other permitted vehicle types include: A3 (city buses), B1 (medium-sized buses), B2 (large trucks), C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled vehicles), and M (wheeled self-propelled machinery).

What is the original tire model for the Honda Vezel?

The original tire model for the Honda Vezel is the TURANZA-215/55R17. All wheel types are equipped with 5-spoke aluminum alloy wheels. The wheel hub is one of the important components of a car, directly contacting the road. Together with the car suspension, it reduces the impact on the car's movement and ensures a comfortable riding experience. It also ensures good adhesion between the wheels and the road surface to improve the vehicle's traction, maneuverability, and driving capability. Additional relevant information is as follows: 1. For tires older than 6 years, even if they are not frequently used or show no obvious damage, they should be inspected by a qualified technician. When inspecting and replacing tires, do not mix brands, models, or tread patterns. 2. Do not mix tires with significantly different degrees of wear. Do not use tire specifications that are not recommended. Do not mix tires with different structures. Do not mix summer, all-season, and snow tires.
