110 p.s.i, Good tread pattern. Grips well on everything so far.
First, where did that kid buy these for $16.99? That's cheap. Second, to the kid who popped more than one. Dude must not know how to install tires. Finally, these tires weigh just as much as any other. Look on J&R bikes website for weight and you'll see. Heavy... what a bunch weak kids out there. Quit being weight weenies!
