My factory spare under the bed is a 285-60. I think I will just use that. If I have a flat on the rear, I will pull one of the fronts off and put it on the rear, and use the 285 on the front. I think that would get me home or to a tire shop for a repair. I don't think I want a full size 37 taking up most of my bed, and I'd have to move it to use the gooseneck..pita.I ran 37s on my 16 PW. Obviously wasn’t fitting underneath. So I got a 285/75/17 (~34”) on the steel wheel for underneath all the time. Then strapped a matching wheel/37 in the bed when off-roading or trips.
Plan would be to put the small one on the front (RF preferred) to get home if needed.
Definitely a pain taking up all that room and a big reason why I’m really trying to keep the new diesel smaller.
