Tire size debate

Tire size debate
I have 19's on rear. Looking to go with the Mickey Thompson EE Street SS for a drag radial.
My concern is which size.
285/35/18 Stock (which is a hair taller than the stock run flats)
26.7 vs 26.9
305/35/18 (which is about 3/4in taller 27.4)
Only concern with the 305 is would you think my shifts be off on my tune from the height difference dramatically

Going over 27 has the potential to rub the liners, YMMV.

Jaycajun on here has the 305s and says they fit nice. I also was reading that over 27in could cause rubbing.
My concern with the 285 was the bite of the tire. I have never owned a drag radial and even though it's about the same size height of my stock tire I would expect to be a night and day difference?

Here is a comparison of stock Pilot Super Sport 285/35/R19 vs Mickey Thompson 305/35/R19:
285 width is 10 5/8"
305 width is 11 1/16"
285 height is 26 7/8"
305 height is 27 1/4"

View of weights for Mickeys....not ideal but it's what had to be done...

I'm running the stock size M/T SS Radials, 285/35R19. They really aren't hooking any better than the MPSS did new. Also, these tires apparently are about 1" taller than the MPSS in the same size. My speedo is off 2mph, confirmed by the GPS in my RD & phone.
Waiting on my order for the new Michelin AS4 tires for the rear. After 3,000 on the M/Ts, there's no way I'd drive these dedicated on the street anymore.

They feel loose at speed. Under WOT they make the car push like it wants to change lanes and has a bit of wiggle. Coming back from drag week, I got caught in a down pour and almost looped it doing about 45 mph. All that for the same 60' times as the stock runflat MPSS.
I had Nitto 555Rs on my truck and never experienced any of these problems. I also drove it in rain and snow without any issues; controlling my speed and acceleration, of course.
And I see I wrote the wrong tires. I'm getting the Michelin 4S.

P305/35R19 Nitto NT05R
no computer trouble around 600whp 7 speed manual, drove fine.
most often the unsettled driving feel is a result of run flats on the front with a non-run flat in the rear... but can be caused by wide front tires in general.

Is your rear wheels the same width as stock z51 wheels?
