You probably know you'll "feel" the road imperfections a bit more, and perhaps have slightly faster wear at the middle of the tread. On the other hand, it will help protect your rims from pot hole damage, and increase steering response feel. It also raises the speed at which you will hydroplane in the rain (square root of the tire pressure x 10 is a rough formula). For just 2 lbs. none of these changes will be significant, as the tires would vary 2 lbs anyway with a 20 degree F change in ambient conditions. If this makes you more comfortable, no major reason not to go for it.
