Probably a dumb question... do you swap out the spare too?

No. The spare is basically a doughnut.

It’s a full size spare.

Interesting thread. I’m going for K03’s soon, have 18’s, no plan on buying five. Rotation is good. Regardless, check the spare’s pressure. Recently had a blowout (Screw) on sidewall on K02’s on my Titan. Pressure in spare was 4 lbs. Shame on me, lucky I have AAA.

The spare also has TPMS, so in theory, you will get a warning if your spare tire's PSI drops below the preset PSI, like your other 4 tires.

That has been answered in many posts, by many inmates, on this forum. The spare is full size, just like the tires that you drive on.

I only bought 4 BFG's. The spare is factory.

Not sure what you mean by doughnut, but my spare, and I was under the impression that all Land Cruiser spares, are the same as the rest of the tires. I plan on doing a five tire rotation. I initially bought four tires and when I’m ready for the rotation, I will buy the fifth.

no such thing as a dumb question!

But I have run across a lot of dumb answers.

I just upgraded to KO3's. I haggled the price down about $20 a tire, so ended up doing 5 because it was in my budget. I also like the way it looks (You can see the spare from the rear profile of the vehicle, it also hangs down a bit more because it's wider and a bigger diameter than stock @275/70R18).

IMO it's purely preference.

For some reason— I thought the tire size of the spare matching was significant due to the all time 4x4 (within a 1/8” or 1/4” of wear, etc.).

I’m new to Land Cruisers, so please correct me if I am wrong!

That would be true if the center and rear diffs are locked on dry pavement. So don't lock them if you have a different size spare in operation.

Otherwise it's not really any different than going around a corner and the outside tire is traveling further/faster.

I will when I upgrade the tires. I did that when I had my Tacoma.
