Hey guys I want to get the biggest size tire with the original stock 20inch rims I already have. My truck doesn't have a level kit. Do you guys think size 305/55 R20 tires would fit without any problems??

Don't quote me in this, but I'm pretty sure that tire will rub.. I know you can fit 33's, but I think they need to be 285 wide or less

it depends on what width your wheels are. if they are 20x9 305's will rub for sure. if they are 20x8 there is a chance they won't rub.

Because of the offset right?

Which stock rims are 20x9 and which are 20x8?

yes, the 20x9's have more positive offset.

as far as i know...2009 to 2012 the 20x9's are the laramie and sport chrome clads. Not sure on 2013 wheels yet

I've got 305/45 R22's on my 2012 R/T and don't have any rubbing issues at all.
