Ours came without a spare as well. I am looking at buying one and mounting it on the back or underneath. We have GSERS Platinum +, but from what I have been reading, if you an inflated spare, then there is no additional cost. If you have an uninflated spare that needs to be mounted, then you are looking at about $163 to do so. If you don't have a spare and they get one for you, so one said they were quoted $400 for a TT tire and then the $163 to mount it. I think it would be wise for me to go ahead and spend a few hundred bucks and get one w/wheel and have it just in case.
