I'm with Denise on this one---I add air before every ride unless I'm in a rush!
I also like to top off to 110psi. I hate how you loose that little bit of pressure when you take take the pump head off the valve, so I figure after that I'm still ahead of 100psi and I'll roll just a little faster with the extra top-off

I wouldn't recommend this, but I've heard of a guy who rolls 140psi and hasn't gotten a flat for years! Your bike can really do some unfriendly things when pressure is that high though...
