About half an hour ago i was just driving along and all off a sudden my tire goes flat in seconds after going over a set of railroad tracks, my question is i filled it back up with air and it is leaking from the bottom of the nossle where u put air into to fill your tire. How would i repair this? I just posted here because i own an integra

 

take it to a tire shop. they need to replace the valve stem.

 

Cool thx
