I am looking to put 20's on my Magnum and was wondering if I could fit a 275/45-20 tire on the car. If not what is the max tire size in terms of width I can go?

Same here. I have some 235 65 17 snow tires on mine and there is room to spare and no rubbing but i can see there is not much room to spare.

I run 275/30x22 in the front and 295/30x22 in the rear without and trouble. And the car is lowered.

the highest you can go is 22's with a 35 series tire.......I have 265/35/22 pirelli's and im good to go not a problem with the tire hitting that bolt....even though its about an 1/8th away from the tire LOL
