That's a pretty big tire, but as long as you have your backspacing right it should be ok. I don't know if it would look right though. I'm running a 255/35/20 tire with a 20x8 rim and 5.25" backspacing.

275 45 20 tires are 28.7 inches tall.. they will fit in the front no problem but the rear is what you would need to look into.. but im pretty sure with a 5 inch backspace they will fit.. anyone else have any input??

sounds like I am up the creek with a 5.5x5 drop and 20x8.5's with 19mm offset. I am trying to determine tire size at the moment. I havent got the rims yet so I need to mount and see.

just tried 275/45's and the fit great in the rear, and probably fine in the front if I was only at like 4 inches of drop. These are on 20x8.5 by the way.
