What have people run on the stock wheels for Auto-X I'm looking at either the Falken RT660 or the Bridgestone RE71R for this upcoming season.

Last year I ran the RT660 on my 2018 Camaro SS 1LE and was pretty happy with them overall.

It looks like there are a few options to run the RT660s but not sure what will fit/be optimal on the car
275/30r19-25.6" front
305/30r19-26.3" rear
or
275/35r19 - 26.6 front
295/35ra9 - 27.2 rear

I know on my Camaro I went down on diameter to optimize the gearing (Stock I would do 78MPH in second) the smaller diameter put me in the power in second on more of the course will a 305 be too much rear tire on the Supra?

stock rear diameter is 26.6" and front is 26"

In the Bridgestones it looks like the best option is
275/35r19 front
285/35r19 rear

opinions? ideas?

I'm going to run the 295s on the back and the 275s on the front. The RT660s are supposed to be the best this year and the RE71s are discontinued. Many of my friends down size like you did last year to put them in the power band, but this car isn't like many autox cars as the automatic shifts so fast. I'll be honest, depending on the track set up your probably going to be in third in the fast sections. I did autocross this car last year twice on the stock tires and I cant wait to run again with proper set up. Front sway bar is already installed and the tires will be ordered this week. March cant come soon enough.

I'm leaning towards the 275/35r19 front and 295/35r19 rear since i'll be sticking with the stock wheels I don't want to pinch 305s too much I've had issues in the past with going that wide and losing some of the feeling from the tires.

front sway bar is on order car should be here in a couple months then just have to wait for some warm weather!
