And how does that work for variable tire temperatures?
What if you plan to drive from the coast to the top of a high mountain? How will you maintain the proper tire pressures during that trip?
PV=nRT
No matter WHAT temp you set your tires to, they WILL vary according to use, ambient temp, speed, etc.
do this once COLD, drive around a lot, do it with tires WARM, interpolate from that data.
The temps dealers use - the mfrs’ settings on door frames - is a guarantee of rapid tread wear and tire replacement.
OEM tires as a general rule are crap. With wear ratings in the 200-300 range (Pirellis and Michelins are typically twice that), compounds are soft, and out of the dozens of cars I’ve owned in my life I have never seen a set of OEMs last more than about 20,000 miles before losing traction, getting noisier, showing wear bars.
Michelins I’ve routinely gotten over 60,000 miles out of by comparison.
Rotate, balance, keep TP within range and they’ll go far.
JMHO.
