Tyre Pressures

[stevierst]

Depending how much riding you do, (new biker will be constantly in the saddle no doubt!!) I'd do a full 'walkround check' at LEAST once a week. (Thats my name for the POWDERS check btw :rolleyes .)
I must admit I do the tyre squeeze every time I roll her out of the garage which is every day for work just incase there was a puncture from the day before, and glance under the bike to see if any fluids have spewed out. It's all dependant on what you trust, know about your bike, and how much your life means to you.
