Why on earth would one tire be inflated more than the other? I can't make any sense of that advice.

I read something about this recently. It's related to the fact that the weight is not distributed equally between the two tires. But the article was specific to touring, where I think the weight difference is greater due to the extra stuff the rider is carrying on the bike.

Personally I pump my Conti Gatorskins up to the max (120 psi front and back) and they've worked fine for me.
