Hi Falcon,

I use a hand pump and inflate to about 60 to 70 psi, but like derik said just press the tyres and they should feel right. If you over inflate, they become rock hard. I use the ZAP cyno bottle extentions, cut it appox till the nozzle fits into the hole on the rim. On the other end of the plastic extention i push fit a 4 mm festo tube which is attached to the pump.

Chaitanya.
