69.735 repeating.

Failing that, Pi is always a good number to use.

I don't even check mine. I just pump my ASMs up until they are decently hard. It works for me.

i have been running mine at 50 psi (40-65max) i dont think i want to go any higher because then they will pop (riding) , they popped a few times at 50 what about 45 psi or is that just not enough?

You know, the lower PSI you run, the more chance of it popping... right?

I run mine near to the 90psi rating (Path plytes). It's good for riding on paved surfaces. No flats thusfar.

Generally just fill up to the rated PSI. Over inflating will tend to blow your bead off of the rim, and under inflating could lead to pinch flats. Most people ride the back pretty much full and a tad less in the front so it squishes a bit more for the wrists. Being 200lbs I'd definitely run the full rating in front and back and go from there.

That's what I was thinking. But I guess eightdip is right, it was a week long ban.
