setting the pressure a little higher in early fall is ok as it will naturally decrease as the temperature drops. it is about 1 psi for every 10F drop (by my monthly monitoring).

i find that it is more important to check your pressures in the fall (monthly) than in the spring (every second month for me) as temperatures rise and the increase is offset by the 'loss'.

I ride about 36front/39rear for the summer and about 38/41 during cold months b/c i know cold weather will deflate it a bit.

i am at about 33.5 psi up front on 18" 255/55 and they still look flat...hmm
