Enough room for 15x10 on a Demon?

...unless you order the wrong backspacing...

Those 275/60R15s are gonna rub the springs with 4.5" BS
I run the same tire on 15x8 Cragers w/ 4.25 BS and only have 3/8" clearance to stock springs, and get a light rub sometimes.

Thats what I can use spacers between wheel and axle right? Excuse me if some words arent correct. English is not my first language. Well meanwhile it is, but I still dont know all words, especially technical.

I definitely moved away from the 15x10 idea, thanks to your guys help. I am aiming for 15x8 wheel and most likely 275/61-15 tires, as they seem easier to get too.
