A little less friction as you inflate the tube is a good thing as it helps the tube stretch comfortably without binding.
As a rule I inflate my tubes to about 60 or 70PSI then I mostly deflate them to allow the tube to reseat and I double check the seating of the tire on the rim. Then as I inflate a second time I carefully check the tire seating on the rim as tire pressure hits about 100PSI or so.
Most people are guilty of WAY under-inflating tubes.
Others just run tires until they are bald at which point you don't really have anything protecting the tube from small stuff you run over all the time.
Ran over a thumbtack 2 minutes after I started riding one day - talk about something to piss a person off. Grrrrr....
