What tire pressure are y'all running? I just got 275/65-18 Duratracs (American Racing AR931 wheels) from Tire Rack. Load Range C...51 PSI max. For the life of me, I can't seem to find the "sweet spot" with PSI.

Greetings & Salutations. Allow me to preface this by saying: a) I've tried searching, prior to this post, and I'm still confused; b) for all the vehicles I've owned, I have to ask each time, because the measurements are taken into account differently. I currently own a 2019 Silverado RST 2.7L, with the stock 18×8.5, 265/65-18. I'm looking into getting 18×8.5 +30mm, 5.94" backspacing, with 275/65-18. Stock suspension, no spacers. I know the speedo will be off a little, but what else am I not thinking of? I know this is the King N00B of all question; and it is the most asked question on every automotive forum, and for that I sincerely apologize...but this whole thing still confuses me. Thank you.
