Ran my tire pressure 6 psi low for 2 years because a guy at a car show said so
I always went by the old rule that you run a couple pounds under what the door sticker says because it "rides softer" and grips better. Then last month my buddy pointed at the wear bars on the outside shoulders of my front tires after only 28k miles on a set rated for 50k and asked me what psi I was running. The insides were barely touched. I pulled out the gauge and I was sitting at 29 on a tire that wants 35, and I do mostly highway miles out to my shop in Reno. Now here's my debate: some of you will say the door sticker is a lawyer number and you should go by the tire sidewall max, while others say sticker all day. I am not sure who is right, so tell me what you actually run and whether you ever caught a wear pattern like mine.
