Has anyone run a 19" wheel as a spare on a car with 21" wheels?

Curious to find out whether anyone has driven their car with a single 19" wheel and three other 21" wheels. I'm trying to get a feel for how much tolerance the wheel speed sensors have for differences in wheel diameter. The 19" wheel/tire combo (245/45 19) is about .3 percent smaller in diameter than the 21" wheel and tire combo (245/35 21) (27.68 v. 27.75 diameter). What I'm interested in knowing is whether that difference in diameter causes the ABS, traction control and other systems to go into failure mode.

I have not done this but see no concern as worn tires have this much discrepancy at times.

Can the 19" tire/wheel combos fit in the front trunk?

Don't see why not, but it will take up a lot of space though

Yeah there is just enough space for the the factory 19" wheel and tire in the frunk.
