Interesting article in AOPA magazine about 2 months ago about tires.
There was a comment in there that you should DISCARD tires that have
been run at pressures >10 (I think it was 10) below recommended pressure
because of deformation of the structure.

Same thoughts here - I keep nose @ 45 and Mains @ 55. No matter what I
also make sure the mains are the same - no need for more braking on a
t/o run just to keep the airplane straight. T/O roll is SUBSTANTIALLY
different with low tire pressure.

Closest I've come to being killed in a plane is low nose gear tire
pressure. I had been flying aerobatics in a super decathlon all day
when the instructor decided he wanted to fly my Velo. He weights over
250#'s. I was experimenting with tire pressure and it was about 15 to
20 #'s. The runway was 3000 ft. The nose would not lift because the
nose went down about 2 inches on takeoff run. It finally lifted at 85
knots and I cleared the trees by less that 20 ft. I was also full of
fuel. Density altitude was not the primary problem in Louisiana
although it was over 90 degrees. Recommend over 30 #'s and think about
the nose drop with loading.

I was trying to soften the landings some years back and had the
brilliant idea (BRILLIANT I say) to lower all the tire pressures. All of
them to 30 lbs. , it worked great with one person on board. UNTIL high
density altitude day, 95 degrees F and at gross weight. Used most of a
6000 ft runway before I bounced the plane in to the air to get rid of
the rolling resistance from the tires. Be careful how low you try to run
the pressures. Later testing found that weight vs. tire pressure really
changes takeoff distance.
