Well Dougy,
The motor will not matter since he has 5.13s.
Like yourself, I was also just giving some advice based on the little knowledge I've accrued while daily driving a Jeep , banging on it pretty good, and doing my own work on her for 6 years. It's just my opinion that if he wants 37s with this setup, I don't see a reason not to get 'em right now cause There's really not much difference in those tires (depending on brand).
I was just lol' ing at the post "Stick with the 35s if you want to drive it..."
They're 36s anyways, right?
I will admit that I've never daily driven a JK on 35s or 37s, but then again, you ain't neither. I'll agree to disagree.
But yes, Seth. I think it will fit in your garage
