I'm familiar with using a tire pressure chart as a baseline for inflation. Many threads here point people to
https://www.goodyearrvtires.com/pdfs/rv_inflation.pdf
However that's just for a small number of tires (Endurance trailer tires, G614 RST, G670 RV and G670 RV MRT), none of those even come in the size my Class C has (LT225/75/R16).
I tried searching the net in general and haven't had any luck. Is it just that they only publish charts for RV/Heavy truck tires? Or is my 'google fu' really bad?
Thanks!
