Tire Stretch

[sLow_E36]

I currently am running Nankang 215/35/18 on my 10.5 miros which is a stupid amount of stretching. A buddy of mine is hooking me up with a set of Hankook Ventus V12 tires 225/40/18.
I went online to willtheyfit.com to see how they would look but I can't tell from those pictures. So if anyone has experience with this setup or has knowledge on stretched tires is it going to be a stupid stretch and do i have to worry about debeading easily. The main reason why i need to know is cause I'm in the military and if i get stuck or something happens i got no tools or buddy around to help me

well 225/40 is wider and taller than a 215/35 so I cant see it being worse than a 215/35. Both sizes will be massive stretches however
