"Buy a TPMS, and set the pressure by it." About all I can say is this is a first. Actually I have a lot to say as I do not see this as a better way. Yes, running more pressure than needed will not hurt the tire and will decrease the pressure/heat increase which is normal. If you look at the sidewall of your tire it will say XXX max press COLD. Pretty sure Goodyear knows the pressure is going to increase when the tire warms up, even going above the max pressure... so what? It's no longer a cold pressure.
I do run 5 psi more than the inflation/weight table because I'll still drive when there is a strong cross wind. It can shift enough weight to the down wind side so I see more than the normal 10% increase in tire pressure.
