Of course, I have to explain it every time I go to the tire shop to get rotated.
“The spare goes to the right rear, everything goes counterclockwise around the car, the left rear goes to spare.”
And I have to watch them to make sure they actually do it.
That's an impossibility out here... at least at the chains.
Radials, they absolutely will not cross-rotate.
At some point in the past, there was apparently a problem with the belts breaking if the rotation was reversed.... of course, in the 80s, directional tread became a thing and most tires these days are directional, so cross-rotation would mean dismounting and flipping them on the wheel.
There are a lot of myths that persist in the auto "care" world.
3000 mile oil changes. That's recreational oil changing, a waste of money, and bad for the environment.
No auto maker has ever recommended 3000 miles.
I went back through Toyota service manuals as far back as I could (early 80s) and they were always 5,000 for severe service, 7,500 for normal driving.
Early 2000's, they added a maintenance light, which was a 5,000 mile clock, and they dropped the 7.500 mile option.
Then in 2010, they started going to 0w20 synthetic and 10,000 mile intervals.
