I'm looking to put Overland rims on my 2011 liberty... I may need some advice as well...
but... from my research... overland rims being 20x8, from factory it runs a 265/50 tire. If you can fit a 265/50 tire and not rub then you should be perfectly fine. if not then you would need to run a smaller tire (whether it being tire width or ratio of rubber or both) that would BE SAFE on a 20x8 rim with your particular size vehicle. overall tire size is what will determine if it will fit in your wheel well.
the question is whats size tire we should use on Overlands without rubbing but still being safe and drivable... I just wanted to find out from someone else with exp so I don't have to find out for myself the hard way
