Hello Chris,
I am new to the forum and looking into some new wheels and tires myself and wish to maximize tire size without lifting or modifying. My 07 Limited stock wheels need replacing since I think I ruined them, another story. From what I gather, without any modification or lifting, a 32" tire +\- is about it. You can slice it many ways with rim size, but I think for 17" the max tire size for stock is 275-70/R17.
It would be great if others could verify.
Another question I would like to ask members is what influences their decision on rim size?
Roger
