I got some decent goodyear a/t tires a couple of years ago. Apparently they are an e rating (10 ply I think). I had nitrogen put in them and they filled the tires to what the door sticker says (32??). From what I understand the door sticker is for the stock P tires, right? These new ones are LT e rated. What should I use for tire pressure for these? I will add air to the tires. I now know nitrogen was a total waste. Thank you.
