anyone who tells you to run low tire pressures isn't steering you in the right direction...
if you go too low and really pull thru a turn you can pop the beed on the tire or kiss the rim to the tarmac and all sorts of crazyiness will ensue.

lower pressures shold only be used on track tires (r-compound or similar) something designed with a stiff sidewall made for lower pressures.

if you know your tire pressure will grow (for example 8 psi) fill to about 9 psi below max rating cold.

just a saftey tip i've learned over the years.
