As the title really. I pumped up my tyres when I started cycling to work a few weeks ago. Since then I've just given the tyres a squeeze to see if they still feel firm. Would you recommend getting the pump on them more often to check the pressure? Also, when I pull the pump off, there's a small release of air as the valve disconnects (half a second or something). Should I be putting a bit more than the correct pressure in to account for this?
