Question: what is the difference between 2 ply and 4 ply?
Answer: There are differences between tires with different number of ply. A 4 Ply tire is more resistant to punctures, can take more load, and take tire repair better than a 2 ply. A 2 ply tire is usually less expensive than a 4 ply, can't take as much load as a higher ply tire and tends to flex more when hot.
