so my rear tire has a slow leak that i have to fill up about once a week...other that getting a new tire what should i do for the problem?

 

Get a whole new bike. usually seems to do the trick

 

Fill it with a bunch of air and listen for any leaks. Examine the whole tire, looking for anything resembling a cut or hole. Another good idea would be putting slime in tire. That may fill any voids.
Also make sure your valve stem is tightened down.

 

yeah i found the reason its leaking...stupid nail. anyway my treads gettin kinda low anyway so i might just replace it all.

 

I would go the safe route and get a new tire.

 

yea i knew there was a nail in there somewhere. id get a new tire although some people plug it.
