Know this has been discussed a ton so I apologize if this has been posted.

I have an 11 now that I'm trading in on a 15 next week assuming in shows up on time. My 11 has aftermarket Gear Alloy wheels that are in perfect shape. They are 20x9 with an 18mm offset. Will they fit on a 15 and will they stick out any more or less than on my 11? Currently the 305/55/20 tires stick out a couple inches. I'm probably going to swap wheels but go with a different tire like a 285 width. I would appreciate any help!
