Oh - and the original question. I have the 285 spare mounted on the stock 17" steel rim but I am shopping for a Trail wheel so I can rotate it in. My last set of 265s I never used the spare and then struggled to get $50 for a brand new tire when I sold it. Would rather go ahead and use the spare and get and extra 20% on miles before I need to replace again.
I am part of an off-road recovery group and we are required to have a matching spare.
I definitely want the same size-ish tire no matter what rim it's on. The Limited has AWD with a limited slip center diff. I'm not sure what it would do with a speed difference between two wheels.
I had a '99 Jeep with Quadra Drive, so had front and rear LSDs. I got into the habit quickly of rotating all 5 tires. Mismatched tires on an LSD would give you some issues...
The concern for me with the Limited would be that center diff, but I'm not sure how big of a rotational differential would be needed to give you problems.
I'd get a matching spare just to be on the safe side. Not sure rotating all 5 would be necessary, however.

Before I took possession of my 21 TRDORP, I had the dealership do the 4 and I had retained my previous 5th....BTW, it was already a TRD wheel and a BFG AT KO2.
