Front Tire Size on a Demon?

I prefer a bigger tire myself. On stock suspension and front disks. I was able to put a 215/70/14 on the front. I never got any wheel rub from lock to lock. But when the wheel was turned it was only about half an inch from the front corner lip of the fender. So If it were me I wouldn't go any larger on sidewall height. My wheels had 4 1/2 inches of backspace. I'm not sure how it would affect it though with 3.75 inches of backspace.
