I'm at 20,000 miles on my Toyos and I was too foolish to rotate my spare in, I have a lot of tread still left but I feel like it's too late to rotate the spare in

 

The point of buying all 5 isn't for rotation purposes, it's so you have a spare tire that you can actually use

 

Measure them. Not sure the best number, but I'm sure you could find out. If still within a 1/4" or so I'd be comfortable.

 

I'll go against the common response and say no I do not rotate the spare. I find a worn half bald spare mounted in plain sight looks terrible, and a tire cover even worse. I have 35yr old vehicals with the original 35yr old spare not dry rotted and look fine. Of course I'm not planning a cross continent drive on a 35yr old tire, but as a spare it's still what it is, a spare that will work in a pinch.

 

I definitely rotate the spare in. These 35" mickey's cost too much to not rotate in.

And when I do puncture a sidewall on one of my four tires, the spare has similar tread wear to the other 3 good tires

 

I rotate mine in every 5k in the G pattern mentioned above. That way the spare is used and each tyre will have done 20k over 25k .

I paid a lot for the matching spare, so it owes me.

 

Or for the remote chance you ever get a flat its like insurance on the back of the jeep . Least that's how I look at it

I have rotated all 5 since I got them. Seems like a waste of money not to.

 

I think you answered your own question. If you don't understand the mis-matched spare, then rotate all 5. That way, when it's time to replace, you can go with a different brand/size/model and not have the unused spare to deal with. If you do go with the same tire, no harm. You'll have to buy all 5 again, but you will have gone approx. 20% longer between replacement than without rotating the spare.

Gives you more options...

 

Yup. And I'm getting a different type of tire when these five are done.

Folks report problems using a "new" spare put into the mix with 3 well-worn tires.
Wheel speed sensors codes, if I remember, etc.

They date code tires for a reason. Plus the TPMS battery won't last forever.
