I would drop it to about 30 and see what that gives you.

Not ok! You want the most even wear across the profile. Lower your pressure by about 3 PSI and repeat the test until you get it right.

You missed the boat there, he already lowered the pressure and did the test again. Way to read the whole thread.

Really? I answered to the question: Should I lower pressure or not!
