What are the requirements for tires in motor vehicle annual inspections?

Motor vehicle annual inspections have the following requirements for tires: the tires must be intact without severe damage; the tire models must be consistent with matching tread patterns. The maintenance methods for tires include: 1. Regularly remove stones stuck in the tire grooves; 2. Minimize exposure of tires to direct sunlight; 3. Promptly check tire pressure; 4. Pay attention to suspension maintenance; 5. Periodically inspect front wheel alignment; 6. Be mindful of driving habits. The functions of tires are: 1. Supporting the full weight of the vehicle and bearing the load of the car; 2. Transmitting traction and braking torque to ensure adhesion between the wheels and the road surface; 3. Reducing and absorbing vibrations and impact forces during driving, preventing excessive vibrations and premature damage to vehicle components; 4. Adapting to the high-speed performance of the vehicle while reducing driving noise, ensuring driving safety, handling stability, comfort, and fuel efficiency.
Last year during my annual inspection, I got stuck because of tire issues. The inspector carefully checked each wheel. The main concern was that the tread depth couldn't be too shallow - the grooves must be deeper than 1.6mm. I've found it easy to check using a coin. The tire surface mustn't have bulges, cuts, or cracks, otherwise it could blow out at high speeds. The sizes must also be consistent - you can't mix different sized wheels, and my small car got warned about this. Tire pressure needs to be normal as too low pressure affects braking and fuel consumption. I was also reminded that the spare tire shouldn't just be for decoration - it needs to be inflated and usable. Since then, I check my tires monthly to avoid trouble. Safety first! I recommend everyone spend ten minutes checking these points before their annual inspection.
As someone who tinkers with cars every day, I've learned that annual inspections have strict tire requirements for safety. Wear is a key focus—tires with treads shallower than 1.6mm will fail because bald tires have a high risk of skidding. Damage is also inspected; bulges or cuts indicate structural weaknesses that can lead to failure upon impact. Size matching is crucial too, as mismatched front and rear tires can cause handling imbalances, affecting cornering. Slightly low tire pressure might be overlooked, but severe underinflation is dangerous. Even spare tires, though rarely used, will be inspected if they show aging or deformation. My advice is regular maintenance: note the date when replacing tires, as they should be changed every 3-5 years. Simple checks like inspecting treads and using a tire pressure gauge can save you from inspection hassles.
