If you're not sliding, I wouldn't drop them, but if you are, 3-4 psi makes a BIG difference. For hard twisty riding on the street, that's what I do. Sliding is dramatically reduced. This is on an older heavy bike that recommends 36/42. On some of the lighter bikes, the recommendeds are lower. I know a lot of guys who use 32/32 on the street. I don't think I would ever go less than 30 at either end.
A tire gauge is standard equipment on my bike and is used often. Always know what your cold starting point was so that when warm, you can take a reading and then add or subtract the change that you're looking for. If in the course of the ride, you will then have an interstate blast of 50+ miles on the return, stop and inflate back to recommended cold pressure by getting the hot reading, doing the arithmetic, and adding the difference.
I run recommended for normal driving, drop 3-4 for spirited street riding, add 2-3 for continuous interstate, and have gone as low as 30/30 on the track which is 12 out of the rear and 6 out of the front. The hardest riding you can do on the street just doesn't compare to the torture they get on the track. That torture results in heat, which results in higher pressure, that actually puts the tire back to something similar to the recommended pressures. Hope that helps.
