Can a vehicle pass inspection with different tire tread patterns?

Can a vehicle pass inspection with different tire tread patterns? Yes, but the left and right tires must have the same tread pattern. Here are specific methods for tire maintenance: 1. Regularly check tire pressure: Tire pressure is a crucial factor affecting tire lifespan. It should not be too high or too low; inflate according to the vehicle's indicated pressure. In summer, try to keep the pressure slightly lower; in winter, ensure tires have slightly more air than in summer due to thermal expansion and contraction. 2. Inspect wear conditions: Some vehicles may experience uneven tire wear, so frequently check the inner side of tires for abnormal wear, focusing on whether tread depth is consistent on both sides. 3. Remove foreign objects promptly: Debris in tire treads poses potential hazards and may eject during driving. 4. Perform wheel alignment regularly: When the vehicle pulls to one side or exhibits abnormal steering, align the tires promptly to prevent further issues. Wheel alignment ensures even force distribution across all four tires, avoiding excessive wear.
I've encountered this situation before - I replaced two tires with different tread patterns before the annual inspection, and got stuck immediately. The inspection requires identical tread patterns, especially on the same axle. Different tread patterns lead to significant differences in drainage and grip, causing imbalance during emergency braking and making the car particularly prone to skidding on wet roads. Because of this, I was required to change the tires on the spot, which was not only time-consuming and costly but also nearly caused me to miss important matters. During normal driving, I've also noticed that mismatched tread patterns cause tires to wear out faster, reducing their lifespan by at least 30%. I recommend everyone choose tires with identical tread patterns when replacing, or simply replace all four at once. Check the tread depth monthly yourself - if it's below 1.6mm, the tires should be replaced. This approach saves trouble and effort while prioritizing safety.
I've been focusing on car maintenance for several years and understand that inconsistent tire tread patterns are a major taboo during annual inspections. Tires on the same axle must be identical, otherwise it affects vehicle stability; different tread patterns cause uneven friction, extending braking distance by 1-2 meters and significantly increasing accident risks. Legally, many local annual inspection standards explicitly stipulate this point, and tread depth must also meet requirements—below 1.6mm means immediate failure. For daily driving, I recommend checking tire consistency every quarter. If you find different tread patterns, go to a professional shop to replace them immediately—don't wait until the annual inspection to discover the problem, as that's both costly and dangerous.
