definitely what he^^ said... I've not noticed any major tire life degradation from running at the max pressure listed on the sidewall, and noticed about 3-5% better mileage when I kept them aired up...

Pros:
Sharper steering response
Better mileage
Lower tire temp due to less flex(could actually yield longer life)

Cons:
Rougher ride
Slightly longer braking distances(3% or so) due to slightly easier lockup
Less forward traction off road due to lack of tire flex
