As long as it all fits, its all good. Though to be honest the spare shouldnt be a big deal. I have gone over a year without a spare in my car, and in that year I have had one tire eat a saw blade, and another come off the rim due to running a 275/40/17 tire on stock rims on not so perfect road. Both times, not having a spare wasn't that big of a deal, not even a real inconvenience. The only real problem was getting the tire situation resolved within a reasonable time, my advice is to keep a pair of your best old tires laying around that you can have thrown on the rims while you wait for the desired tires to show up.
