What is the difference between 185 and 195 tires?

185 tires and 195 tires differ in width by 10 millimeters. Tires, commonly referred to as such, are typically made of wear-resistant rubber materials and can be classified into solid tires and pneumatic tires, with pneumatic tires consisting of an inner tube and an outer tire. Tires are one of the crucial components of a vehicle, serving several key functions: 1. Supporting the entire weight of the vehicle and bearing its load; 2. Transmitting traction and braking torque to ensure the adhesion between the wheels and the road surface; 3. Reducing and absorbing vibrations and impacts during driving, preventing severe vibrations and premature damage to vehicle components, thereby ensuring driving safety, handling stability, comfort, and fuel efficiency.

What is the standard for gear backlash?

3ml~4ml. Below is relevant information about gear backlash: 1. Introduction: Gear backlash refers to the circumferential play of one gear when the other gear in a meshed pair is fixed, measured as arc length along the pitch circle. In rotary mechanism transmissions, the pinion is installed with the rotary bearing as a standard component whose tooth thickness cannot be altered. To meet heavy load requirements, the pinion's thickness cannot be reduced. 2. Design principle: To ensure proper lubricating oil film formation between tooth surfaces and prevent gear seizure caused by thermal expansion during operation, appropriate gear backlash must be maintained during meshing.

Can Antifreeze Be Added Directly?

It is not recommended to add antifreeze directly. Before adding antifreeze to a car, the engine cooling system should be thoroughly cleaned, especially during seasonal transitions when the antifreeze level needs to be checked. If the antifreeze is insufficient, it should be replenished promptly. Cleaning before adding antifreeze is mainly to prevent chemical reactions between scale in the engine and the antifreeze, which could cause the scale to detach and affect the normal performance of the antifreeze. The car's cooling system is crucial as it primarily serves to dissipate heat from the engine and provide warm air for the air conditioning. Antifreeze generally needs to be replaced every two years. If a shortage is noticed before the two-year mark, you can top it up with the same color and brand of antifreeze, preferably into the reserve tank. If the reserve tank is empty, it is advisable to check for possible leaks.
