And I can run on mine at 70psi and not get pinch flats as would happen with maybe thinner 700 road tires like 25's.
good point... i ASSUMED road tires... since that what i ride 99% of the time! so my 120 psi recommended tires (700X23) i run at 100 for a nicer ride! (and for my size, too.... no need for me to have 120 psi in my tires!)

my mtb tires.... hmmmmm.... my bad.... i have NO IDEA what is in them.... i ride it so rarely... and i have hubby take care of the air! but they are at less than recommended psi, too!
