Thanks guys!
From my calculations a 10 inch wheel with 25mm offset equals a backspace of 6.484 and when using tru-turn the recommended backspacing is 5.75 but I've read that 6 1/4 will also work.
I think with the 10 inch wheel and the 25mm offset I should get away with less 1/4 spacer to hit below the 6 1/4 sizing.
This is based upon a 10/2 = 5 + .5 for actual width and 25mm equaling .984 inches.
yay math!
