Road Bike Issue

Hey guys,

I'm looking for some serious advice here. I've been riding my bike into work lately (about 21 km each way), and for the last 3 days, at some point in the morning, my front tire goes completely flat. I'll do a quick tube change, ride home, get the PSI up to 115-120, ride to work the next day, then have the same problem all over again.

I check my tire for sharps and debris at each change, am careful on my rides to stay on the nice part of the road (no bumps/potholes) yet have this problem. The only thing I can think of is it is sitting on the south side of the building in the sun, and over the day it gets too hot. Anyway - I'm running out of money for tubes and patch kits..

Any thoughts on what causes this/what I can do to stop it from happening?

Thanks
 
Check the rim for any sharp points, make sure all your spokes are tight and properly seated in the eyelets of the rim. If they are loose they can poke through to the tube. Wrap a couple extra layers of electrical tape on your rim as rim tape. When you install the tire never use tire levers. Levers should only be for taking a tire off that already has a flat tube. Make sure your tire is properly beaded around the entire rim on both sides while inflating. And if you have a presta valve, make sure the the valve core is tight. This can be done with needle nose pliers if you do not have a valve core tool.
 
Get a new tube, even if there isn't a visible lesion in your current one. It could just be worn down, or there could be a tiny hole in it somewhere. 120PSI is a lot of pressure to withstand
