I've been debating the same thing. Mine came with a spare, but the only place to put it is in one of the lower compartments, just lying there, not secured. Question is do I feel comfortable with out a spare on a 3500 mile road trip? The tires are new as of last summer, but that doesn't always help. Road side service is available if you can contact them. There are plenty of places I've been that I don't have cell service. If they do get there, do they have a new tire that you need for a price you don't feel like you've been taken advantage of. Sitting in my driveway I'd be reasonably comfortable changing the tire, They're actually slightly smaller than my E350 van tires. I've got a 10 ton bottle jack, 30" breaker bar and a 150in/lb torque wrench. At night in the rain on the side of the freeway, not so much. I've change 1 tire on my commuter car alongside a busy freeway. Not worth the risk or the anxiety. And grandpa joe's hardware feed and tire shop -- "sure I think we can find a tire that will fit" then charges you twice what it's worth for a used tire that only "fits" Did that once in northern california when I blew a tire on my TT. Still figuring out where to store it, but **** sure it's coming with us weather I change it myself or not.
