Similar situation. I also purchased my CPO 2019 with 28k miles and just bought new BFG KO2 tires from my dealer at 52k miles. Tires are great at 36psi front and 34psi rear. Believe it or not, the dealer had the best price with a manufacturers rebate too. Still had some tread left, but living in the northeast I didn’t want to chance it with winter approaching. This forum is the best for information, insight and tips. Thanks to all!
