Can car tires be replaced with larger ones?

Car tires cannot be replaced with larger ones. When replacing tires, it is necessary to choose the appropriate ones. The specifications of the new tires must match those of the previous tires and must be the same as the other tire on the same axle, including speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. The valve stem should also be replaced. This is because the aging cycles of new tires and old valve stems differ. During the lifespan of the new tires, the valve stem may develop issues that are not easily noticeable. Therefore, it is best to replace the valve stem when changing tires. Regarding installation direction and inflation: if using the original tires that came with the car, follow the manufacturer's instructions for installation. For non-original tires, generally, the side with the production date should face outward. If the tires are directional, ensure the arrow on the tire aligns with the direction of the car's forward motion during installation. New tires are best installed on the rear axle of the vehicle. Placing more worn tires on the rear axle can reduce the rear wheels' water drainage capability, increasing the risk of driving in rainy conditions. Therefore, if only two new tires are being installed, they should be mounted on the rear wheels.

How to Move a Car Without Knowing the Owner's Phone Number?

If you don't know the owner's phone number, you can try the following methods to move the car: 1. You can look for car-moving services in WeChat or Alipay. Since WeChat Pay and Alipay have become the most popular payment methods nowadays, almost everyone uses WeChat or Alipay, and finding a life service within them is relatively simple. 2. You can also try broadcasting a message. If your car is blocked while shopping at a supermarket, it's likely that the owner is also shopping inside. You can ask the supermarket staff to announce a message over the PA system to notify the owner to move their car. 3. Call the 114 hotline to notify the owner. After dialing 114 and selecting the manual service, verify some real information, and the operator can then transfer the call to the owner or send a text message directly to notify them to move their car. This method is quite effective, although sometimes efficiency might be affected due to line congestion.
