I've always done a 5 tire rotation. Well I did once non bias tires became readily available. If you go to a shop with vibrations, shake or shimmy the first thing a good shop will tell you is to come back when all 4 tires are the same diameter. You could always shave one down but shaving down a perfectly good tire doesn't make sense to me.
I rotate tires at oil change every 5K. It requires relabeling them in obdlink mx+ fusion.
Have to drop the spare in the Fall to oil the undercarriage anyhow. I've seen spare tire carriers so rusted up you couldn't drop it if you had to.
5x TRD Pro alloy black wheels PTR56-89210-F2
4x TRD Pro Center cap, new red ring PT280-89210-F2
4x Lug nuts black PT076-60200-02
Worked for me.
5 tires obviously last longer than 4 when rotated. And when 4 are wore out you can pretty much rest assured that they will no longer be available when you need new ones, if you didn't rotate the spare it will not match. I went with 5 265/70r17 AT3W Wildpeaks 2 months ago and the AT4W are already out. And they are different diameters. Same thing happened with my Taco, the original KO tires were replaced with KO2's soon after I got it.
Personal preference and mine is 5 identical tires and wheels. In rotation.
