My door stickers say 30 PSI on my '07 and that makes my BFG AT's look like they are half flat. What is correct? If I go to the tire shop they refuse to put more than what the door says. I don't mind running that pressure just the tires look funny at that pressure and make a lot of scrubbing noise at that pressure during sharp turning like in a parking lot.
Hello, I’m running BFG AT’s M+S on my 2015 Suburban PPV and I had that scrubbing noise as well. It is the tires being oversized and rubbing on the fender liner when you kick your wheels over all the way. I went to my mechanic and he took a knife and just cut out the offending spot where it was rubbing. It is just a cardboard / finer like cover coming down from the fender. You could even do it yourself. As far as air pressure goes, mine is a heavy truck, so in order to keep my tires from looking like they are low on air, I have mine sitting all at 50 psi. My shops do it, no problem. If not, go to a gas station and add the air to whatever you want to have. They are YOUR tires. Btw....I have done this pressure with all of my trucks before and have NEVER had any issues or wear patterns at all. Good luck !!!
