70 mph nailed to 3000 rpm

Hey, wait …I’ve lost 200 rpm. Something tells me my new front tires might not be the same as previous, or I have a bad ECU, or maybe my pizza box is bad

That's normal, it's about 100 rpmpy (rpm/year). Monotonic, derivative < 0 but not constant. Until the crank spins backwards of course.

I’m used to a lot of things shrinking but not distance.

You been on the road too long. Cooking dinner on the engine is a old Truckers hack.
