Everybody has an opinion.

If I tried to use that chart, I'd be under the recommended minimum of the tire manufacturer. Not good! Me and the bike are pushing 250#.

I inflate to gain handling and sure footedness. In my case, with a 35 on the front, and a 40 on the rear, that works out to 85 PSI in both tires.

I've tried less, and the tire starts to feel "loose" when going around tighter corners and curves. At 85, everything feels nice and secure. (I start to tell a difference at 75, and it is very noticable at 70.) 85 also keeps pinch flats at bay, and it still rides nice (most likely due to the tire size.)
