The right tire pressure for your ride is personal and depends on your riding style, the terrain you'll be riding and the conditions of that terrain on the day you're riding. What you see below is a recommendation of a starting point pressure, a "ballpark" if you will, based on rider + gear weight and tire width. You'll also see a decal on your wheels indicating maximum inflation pressure. Never exceed the maximum inflation pressure of your tires or rims. Enjoy your ride!
