I have a 2019 ram 1500 bighorn.  I want some new wheels and tires for it.  Dont have much room for lift and still fit in my garage door. I wouldn't mind going up a size if possible without rubbing. I believe my wheels have +19 offset.  What offset can I get with an 18" wheel and not rub with 275/65 or one step bigger if possible. Thanks for any help!!
