The first number, 215, represents the tire's width in millimeters. The second number, 60, is the aspect ratio, which is the ratio of the tire's height to its width. The third number, 15, is the diameter of the tire's rim in inches.
The 195 tires are narrower than the 215 tires, which means that the 215 tires will provide more contact with the road and therefore better traction. The 215 tires also have a higher aspect ratio, which means that they will be more comfortable to ride on. However, the 215 tires are also larger overall, which means that they may not fit in the same wheel well as the 195 tires.
If you are considering replacing your 195 tires with 215 tires, it is important to do some research to make sure that the 215 tires will fit your vehicle. You should also consider the impact that the wider tires may have on your vehicle's handling and performance.
