tire pressure

"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.

There is a better way.

Buy a TPMS, and set the pressure by it.

We found that running with the pressure at the suggested pressure by weight caused the tires to heat and go over the recommended max pressure by the manufacturer.
We increased the pressure, and found the tires did not heat as much and stayed under the max pressure.
So we increased it more and found it heated less, did it again, no change, and that is where run our tires. 10X22.5 Michelins at our load 97 pounds is where we run. recommended pressure was 90.

Plus. Look at the tire sidewall.you will see a max. cold inflation pressure. Don't exceed that number.

Tire pressure/weight tables are set up for actual weights.

If you are close to your axle's GAWR, then use the PSI recommendation on the plaque likely near the driver's area that lists GAWR's, tire size and PSI.

Longer term answer is get it weighted and set pressures accordingly.
