Do you have any better shots of the 1.5/1 lift on stock tires? You are the only person I know with this lift and stock tires haha! I just bought a set of 1.5/1 also. I know I am set on 275/70/17 tires with no issues. If I can fit 285s without BMC, i prob would do it!
Just phone pictures, hopefully they help! I read a post that somebody fit 255/80 Coopers on a TRD Pro with fully stock suspension but we’ll see. Look at at my tire a full lock I have a feeling they’ll rub.
