10” Rim on rear of stock ‘72 Demon??

All,
I’m thinking of running a 10” rim on back of my Demon.
Stock wheel well and stock wheel tub, springs moved in 3”.
Have a deal,on 15x10” with 4 1/2” backspace.

I’ve rin 15x8” in the past with 4 1/2” backspacing, wondering if the 2 extra inches will rub on either inside or outer wheel well.

Thank you!

Wally.
