Better 5 over than 5 under for any tire pressure! Unless you want to be like the Ford Explorer and Firestone tire affair.
One thing which has always puzzled me is that while they always say its the cold pressure which is important. What if you do wake up in the mountains of AZ say and the pressure is just below the tire manufacturers max and then the temp rises say 4o deg F (which should be a 4psi change) over the course of the day say . Should you adjust for that?
you shouldn't adjust tire pressures like that or for that...and there is no reason to be anywhere near max inflation, cold
That can be VERY bad as it can cause loss of control...for many reasons
depending on the tire, the MAX inflation should be 44-51psi.....if you start at 36psi...you wont get anywhere near that
