BTW: Is the problem more back tire or front tire?
Have you tried a slim tube?
it happens to both the front and back tires equally.
by slim tires do you mean 23s? if yes than i have tried them
Aren't you the one who deliberately flattens his tires (lets the air out of his tires) every night?
I know so many people who re-pump thier tires everyday, thats why i purposefully repump them everyday
