Best Location for Donut Spare?

[Crickett]

So I haven’t had my ZHP on a square set of wheels and tires—245/35ZR18 Michelin Pilot Sport A/S 3s on 8" 135Ms—for even two weeks and this happens:





Only eleven days and 535 mi on the tires and no road hazard insurance … d’oh!

Anyways, since I have the same size wheel and tire at each corner, I wanted to ask the Family’s opinion on which wheel position would be best to install the donut until I can get a new tire. The flat occurred on the left rear, so that’s where it is now, but would there be any argument to putting it on the front axle instead? I thought that, since our rear tires wear faster than fronts, it might be smart to put the donut up front to reduce its wear. Or do you think it won’t matter much at all?

Alternatively, I do still have my set of winter wheels (205/55R16s). Would it be beneficial to put two of those up front and two good 245s at the rear, saving wear on my donut? Or maybe just drive on all four winters until I can get a new 245 (it has been kinda cold here recently … )?
