The tires are marked '130 PSI'. I read at Sheldon Brown's website that the ratings marked on the tire should be safe and usually reflect about half of the actual 'blowout pressure'.[1]

I weigh around 210 and after getting a pinch flat days after getting my first bike and having had no spare tubes at the time, I suppose I've been thinking that slightly over-inflating would be safer flat-wise than under-inflating. It sounds like perhaps I could take it down a bit to 120 or so. What do you think?
