Tire Question? do they grow when mounted?

SunF 22x10-8 22x10x8 ATV UTV A/T Knobby Race Replacement 6 PR Tubeless Tires These Tires Look A Bit Shorter Than The Tires They Are To Replace.

 

I just put dirt devil's on my ATV, then a month later put them on my wife's ATV. The fronts are the same size on both. I set an unmounted one next to the one on my ATV, and it was around an inch shorter.
Yours look to have a much rounder profile, I would definitely say it will be the same size once mounted and inflated.
