how do i find the leak.....i have to way to put air into the tire .... i havent looked yet so it might be a huge gash but.......bumblebee said:Find the leak before you freak!!! It could be a simple puncture that can be repaired and you go on, no problems...if it is large hole you need to make a decision considering safety and your tire. If it's a side wall, no brainer, new tire...remember, those tires are the only things keeping you upright and going. You want to ride on them with doubts???
