When I bought my 2015 last september,there was NO OPTION for a spare.Go to the ram promaster city 'build and price" for the 2016,no spare listed as an option last time I was on there.About a month ago.What you bought and paid for is listed on your Monroney, read that carefully. You may not have gotten the spare because you did not pay for it. That's not being screwed it's not doing your due diligence. Many vehicles today do not have spare tires but opt for a repair kit instead and many are very expensive vehicles too!
Im still waiting for someone to post a picture of one installed too..haha.
