2012 liberty jet edition, spare tire. Can I replace the doughnut with a full-size spare?

[Pharunk]

My 2010 liberty sport had a full-size spare tire. My 2012 jet edition has 20 inch rims with a lower profile tire on it with a doughnut spare. My question is will a full-size 20 inch rim spare tire still fit underneath where the doughnut is stored? I’m guessing the answer is yes but I’m not sure if the larger rim and tire will fit in that same place.

I have a 245/75R16 under there, which is 30.5 inches in diameter. It fits fine. I have heard that the next size up from that still fits, although you may have to let a bit of air out. Check the diameter of your spare and if it is 31” or under you’ll be good.

Thanks, I’m running 245/50/R20’s on my liberty. I measured diameter to top to bottom at 29 inches so I think I should be fine. Appreciate your response!

I replaced the doughnut spare with a full size spare on my 2012 Jet Edition. It fits fine. I replaced the low profile tires as well.
