Riding around with soft tires can open up a can of worms, full of inconvenience, as well as dragging down your spirit and top speed. Always check your tires before heading out on a ride; some thinner walled inner tubes can lose between 5 and 20psi a day.
Either give them a squeeze by applying ﬁrm pressure to the top with your thumb or ping them with a ﬁrm ﬂick of the ﬁnger. They should produce a drum-like hollow sound and feel very ﬁrm when at the correct pressure.
Use a good ﬂoor pump like the JoeBlow II from Topeak available now at Ace Bike Shop (we use it at the shop)!
