Hi all -
I commute by bike to work most days of the week and got a flat a few weeks ago. I replaced the tires with Slime Tubes but for some reason I can never get adequate pressure on the tires. No matter how much air I put in there, they always seem to sag when ridden. There's obviously no leak since the slime stops leaks, and the pressure never seems to change after I've inflated it...it just never gets to a maximum level when I keep inflating it with are (using a hand pump). I do hear a click in the cap of the pump whenever I'm inflating it and it's near maximum pressure.
Never seemed to have this problem using regular tubes. Anything I'm doing wrong?
