Yes, seriously underinflated tires are not good. But there is a happy medium.
Super inflated tires will have less contact with the road and will bounce more on the upper surface of uneven pavement irregularities. The millions of tiny vertical bounces will add up to wasted forward motion. Medium inflated tires will make better road contact and thus transit forward motion energy better.
My tires say maximum inflation recommended is 105 lb/sq.inch....that's "maximum". I keep them at 95 on the rear wheel and 85 on the front. That is nowhere NEAR low enough to get a pinch flat, mind you. With these pressures, I have stable steering and a smooth quick ride, and I'm not bouncing off every pebble like a kangaroo or feeling every nasty bump right on my "keester".
Lisa, I keep my tires inflated to 130; the maximum is 145. I don't bounce on anything except large bumps; my daily rides are smooth and fun. I don't have road shock. My cruising speed is between 16 and 19 and I can increase my speed if I desire. I prefer more air pressure because it gives me a better ride. If I kept my tire pressure as low as 95 I would be slooooooooooooow.
