Do you change all four of your tires?

A couple of years ago I needed to replace the front tires on my daily a 08 Ford Expedition with auto 4x4. I had aggressive Goodyear E 285/70/17 on it from when I used it for work. But the front tires were shot and the rear tires had years worth of tread left on them. I wanted to go with a hywy tread but at $400 per tire I couldn’t swing all four in one shot so I ran the new front tires for about six months before I switched the rear tires. There was no issues with anything including ABS, traction control or even the automatic 4WD.
I use the Expedition for pulling multiple different trailers including my 30’ camper so the tire selection is necessary, the bonus was getting 75K out of the tires.
Well that has a transfer case. Totally different animal.
