What is the tire pressure for off-road vehicles?

Off-road vehicle tire pressure standards: Standard tires: 2.4-2.5 bar, Reinforced tires: 2.8-2.9 bar. The maximum pressure should not exceed 3.5 bar. Hazards of over-inflation: Tire friction and adhesion decrease, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components. Hazards of under-inflation: Increases friction coefficient with the road surface, leading to higher fuel consumption; Makes steering heavy and prone to deviation, compromising driving safety; Increases movement of tire components, causing abnormal heat due to excessive rolling; Reduces functionality of cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim causing damage to the bead area and abnormal wear.

Can illegal cameras capture speeding violations?

Illegal cameras can capture speeding violations. The following is an introduction to the principles of speed detection systems: 1. Speed measurement methods: Speed measurement is divided into fixed-point speed measurement and interval speed measurement. Fixed-point speed measurement measures the instantaneous speed of a vehicle, which must not exceed the speed limit of the road section. 2. Speed measurement distance: Interval speed measurement calculates the average speed by dividing the distance traveled by the time taken. If the average speed is higher than the speed limit, it indicates speeding. 3. Speed capture rate: Current speeding violation capture systems can achieve a vehicle capture rate of 100%, with a recognition time of about 1 second. The daytime vehicle recognition rate is over 95%, and the nighttime recognition rate is over 90%. The applicable speed range is 5-180 km/h.

What Type of Gasoline Does a Cadillac Use?

Cadillac uses 95 octane gasoline. Below is relevant information about Cadillac gasoline: 1. Gasoline Octane Rating: The gasoline octane rating represents the ratio of the actual gasoline's anti-knock properties to those of standard gasoline. The higher the rating, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher octane ratings are not necessarily better; the appropriate gasoline rating should be selected based on the engine's compression ratio. 2. Compression Ratio: The primary criterion for selecting gasoline octane rating is the engine's compression ratio, which is also a core energy-saving indicator in modern vehicles. Engine operation consists of a continuous cycle of "intake - compression - combustion - exhaust - intake" in the cylinders. The compression ratio is the ratio of the cylinder volume when the piston is at its farthest and closest points in the stroke.

Where to Obtain a Vehicle Inspection Report?

General comprehensive inspection stations can perform it. Below is relevant information about vehicle inspections: Conditions: Vehicles whose condition does not match the records in the driving license or vehicle files, or whose license plates or driving licenses are damaged, incomplete, illegible, or self-made. Notes: The vehicle's exterior must not be modified. The tint of glass sunshade or explosion-proof films must not be too dark (items inside the vehicle should be visible from one meter away; mainly applies to vans and trucks, but not to passenger cars with fewer than 5 seats). Vans and trucks must have enlarged rear license plates. The number of spring leafs must not be increased or decreased. The number of seats in vans must not be altered, and a fire extinguisher must be present. The cargo compartment of box trucks must not be modified (no side doors, no roof openings, no tailgates). The size of tires must not be changed, and the tread patterns of tires on the same axle must be consistent. Vehicles with unresolved traffic violations or those impounded by the court cannot undergo annual inspection.

How to Automatically Fold the Rearview Mirror?

The method to automatically fold the rearview mirror is to press the rearview mirror folding button located near the driver's side electric window control. The driver can fold it from inside the car. When starting the vehicle, the rearview mirror will automatically open. The function of the car rearview mirror is to reflect the situation behind, beside, and below the car, expanding the driver's field of vision and reducing the occurrence of safety accidents. The method to judge the distance of the car by looking at the rearview mirror is: 1. Use the center of the rearview mirror as a reference line. When the car body is on the outside of the reference line and the rear vehicle cannot be fully seen, the distance is 5 meters; 2. When the rear vehicle can completely appear in the rearview mirror and the car body is pressed against the reference line, the distance is 10 meters; 3. When the rear vehicle is pressed on the central axis of the rearview mirror and there is still a car's width between the vehicle in the rearview mirror and the outer edge of the rearview mirror, the distance is 15 meters.
