1. First, you can observe the logo on the side of the tire. Usually new tires will have the tire's trademark and related parameters on the side, while retreaded tires are mostly fake. Try to pick it out. If it is a retreaded tire, you can pick out these marks. Especially the production date. Changing the production date is a common operation for retreading tires.

2. Observe the lanugo. New tires have lanugo hair, but retreaded tires cannot fake lanugo hair

3. Observe the tire pattern gloss. The pattern of new tires has a soft luster, while retreaded tires will be over-waxed due to gloss, making them look unusually bright and have shallow patterns.

4. Observe the tire elasticity. New tires have better elasticity than retreaded tires. Use a key to lightly scratch the tire. If it is a new tire, the scratches will disappear quickly, but a retreaded tire will not recover for a long time, leaving scratches.

5. Pull the tire wear mark with your hands. Generally, the wear marks of retreaded tires are affixed and can be easily pulled off, while the wear marks of new tires are integrated with the tires and are not easy to be pulled off.

6. Price. The price of new tires is usually similar to the market price and is very stable. And if the price of the tire is too different from the market price, then it may be a retread tire.
