As a general rule, I run my tires (Freq. G's) at 120 psi. Recently though I switched riding spots from a really nice basketball court to a parking lot at the university I work at... from what I think I know, most basketball and tennis courts are laid out with a somewhat forgiving, cushioning surface so that folks don't blow out their joints when playing on them. My rolling tricks feel REALLY good and solid at the bball court; the feedback from the ground when pushing forward into tricks is great at 120, and everything feels solid when rolling.
On the other hand, the university parking lot (where I moved to because the foot traffic at the courts started becoming a pain in the a*s to deal with) is a really hard, non-forgiving asphalt. At 120, pushing into tricks and rolling them just feels really squirrelly, and it seriously feels like I'm a beginner doing basic rolling tricks there. Tons different then the bball court... spinning is fine, but controlled rolling just seems harder there, and I'm suspecting I'll need to adjust my pressure.
So, long story short, do any of you folks adjust tire pressure regularly for different spots? And how much do you do it by depending on where you ride? I remember one of my Japanese bmx mags have a chart with surface pics and the recommended pressures you should run, but I think I lost that issue when I moved back from there... Thanks in advance!
