Tire pressure to prevent pinch flat?
I sustained a pinch flat the other day on the rear and I was wondering if my tire pressure was the cause. I know I have a lousy 19" tire with MX sidewall, but for now that's what I've got to work with. I was running 12 PSI in the rear at the time of the incident. I've been thinking 14 PSI might help - any suggestions??

12PSI is pretty much the high end of what i'd run in a rear tire. Have you tried a heavy duty tube?

Weight, terrain, speed, obstacles, suspension, stiffness of the tire's sidewall all play into what pressure will work to prevent most pinch flats for your riding. Heavy duty tube combined with a stiff wall tire and higher pressures will help prevent most pinch flats but the tradeoff is normally some loss of traction.
My approach for a given tire is to look at the swipe/wipe on the rim. This is where the tire has flexed back onto the side of the rim and wiped (or swiped) some dust from the edge of the rim. 2-3 mm is the general guide of a good working pressure - if your getting swipe marks of a quarter of an inch add a couple of pounds pressure. If you rim is not getting swiped - then the tire is not flexing enough and you should lower tire pressure a couple of psi. Same applies to the front tire.
