Good idea.

I'd be interested to know the difference in tire sizes for the Previa, sounds like it could have been a couple inches. With regards to your "rotate four or five" question to yourself: No evidence, but it seems the difference -- in tread wear between a new tire (spare) and whatever wear is on the same model driving tires -- can't possibly be enough to damage the drivetrain in less than a few hundred miles. Then again, if you've got a free rotation package, why not rotate all five at a time?
Do GX's come with a matching spare wheel? 4Runners don't. For whatever weird reason they paint the spare yellow on some. Others have a steel wheel. Obviously Toyota doesn't think customers use the spare as a 5th tire in the rotation. Or they think someone wants to run a yellow wheel?? Odd choice
I don't think a different size spare would make any difference over a few hundred miles. The axle differential would have practically zero additional wear through the slight offset in the spider gears. And the tire height/speed difference front/rear would be small given that half of the effect is compensated by the rear differential. Because it's a helical gear type torsen diff - there's not clutch plates or other wear surfaces to wear out. Just a slight internal rotation difference. There would be some friction on the gear teeth due to the rotational difference, but it would be pretty small. I'm sure there would be some additional resistance and a small drop in mpg. I doubt you'd notice it. This is a pretty good simplified explanation of what's inside. https://pdfs.semanticscholar.org/1e59/16df64c80cd903bdaf6f68d8b1bf93e8b033.pdf

Unless you're still under warranty, I'd still refer to post #2 in this thread that I wrote about. I really wouldn't chance it if at all possible. Even if warranty covers it, it is a very long repair, maybe a couple of weeks unless they have everything at the dealer.
I know I won't do it.
Just my 2 cents worth of experience.

So, I am resurrecting this thread because I am feeling like a dumbass...
I'm reading that a 285/70/17 (32.8" OD) fits beneath the 460, but I can't seem to get my 255/75/17 (32.1") in there. What could I be doing wrong? I will say, I used to work at a tire store and did this for a living (lol) so it shouldn't be this hard, right? What seem to be happening is its getting squeezed between the rear sway bar and the factory tow hitch bracket.

The person in this thread referencing the 285/70 in the stock location is talking about on 4Runners. You’ll have to trim the hitch and possibly deflate the spare some to get it to fit.So, I am resurrecting this thread because I am feeling like a dumbass...

Haha, a 285/70/17 most definitely won't fit under the 460, but it does just barely fit under a 5th Gen 4Runner. I made my 255 fit but I had to trim the hitch a tad in order for it to clear and even then by only a millimeter or two lol.

So, the burning question is, will my 265/70/17 Ridge Grapplers fit under either our 470 or 460?
Did you have to trim the bracket the hitch bolts to? My tire seems to have about and 5/8" overlap over that bracket. It appears that If I cut off enough I'll end up cutting off two of the hitch mounting points.
Maybe I just need to bite the bullet and buy that rear door spare mount...
Mine did not fit.....LT265-70x17
Factory tow & KDSS
$1100 later...RidG Swingaway carrier.......wife hates it...
