What are the differences between 700x28 and 700x32 tires in terms of performance and suitability for various riding conditions?

700x28 tires are narrower and typically offer lower rolling resistance, making them faster on smooth surfaces. They are suitable for road biking and racing where speed is important. 700x32 tires are wider and provide more stability and traction, making them better for rougher terrain and gravel riding. They offer a more comfortable ride but may be slower on smooth roads. Choose based on your riding style and the terrain you will be riding on.
