benne Posted December 3, 2022 Share Posted December 3, 2022 (edited) Hey all, just purchased a 2019 MKZ 3.0T AWD with 30k miles. The car came with the 19" wheels with the 245/40/19 size tires. I live in Minnesota and the car has Goodyear Eagle Touring tires which are working OK in the snow and ice storms we are getting. I'm contemplating purchasing snow tires, which will stay soft as the temperatures drop towards 0 degrees and below. I am curious if anyone has put 17" wheels on the MKZ 3.0T? Are there brake clearance issues? The obvious reason going 17" is the cost of wheels and tires are drastically cheaper, and the ride quality is more comfortable with the larger sidewall. Are there any tire diameter specs that need to be within a certain measured range to not cause damage to the AWD system? The Tire Diameter of 245/40/19 is 26.7 inches. It would be nice to free up some space between the edge of the tire and the fender/wheel well as snow and ice can build up and rub/obstruct the tire when turning. It looks like 225/55/17 also has a tire diameter of 26.7" 225/55/17 = 26.7" diameter / 0 radius change 235/45/17 = 25.3" diameter / 0.7" radius change 225/45/17 = 25" diameter / 0.85" radius change 235/50/17 = 26.3" diameter / 0.2" radius change I looked in the manual and couldn't locate any information regarding these requirements.

Hi benne and welcome to the Lincoln MKZ Forum. You can go to an 18" wheel, if you wish, but a 17" wheel is too small to avoid brake/suspension interference. And whatever you do, you will want to keep as close to the factory/stock overall wheel/tire diameter as possible. This will keep your speedometer/odometer accurate and help avoid any suspension/fender interference. See here: https://www.tirerack.com/wheels/results.jsp?autoMake=Lincoln&autoModel=MKZ+3.0T+AWD&autoYear=2019&autoModClar=&package=false Hopefully the link above will work without needing "cookies". If not, just perform another search for wheels for a 2019 MKZ 3.0T AWD. Let us know how you make out and good luck.

benne Posted December 3, 2022 Author Share Posted December 3, 2022 Thanks for the reply! Could you please elaborate on "feeder" interference? I'm not familiar with that term! Usually work on older vw/audis Quote Link to comment Share on other sites More sharing options...

Usually work on older vw/audis Im pretty sure he meant 'Fender Ineterference', meaning don't get a large tire where it will rub the fender, or quarter panel. Also too low of a wheel offset can push out the tire and could cause some rubbing issue on the quarter panel. Quote Link to comment Share on other sites More sharing options...

Usually work on older vw/audis Hi benne. Oooops...typo! Yes, "fender" interference, as fusionff stated. Thanks fusionff! I went back and corrected the typo. Good luck.

benne Posted December 4, 2022 Author Share Posted December 4, 2022 Ah thanks for the clarification! I did notice the fenders on these cars are more "widebody" inspired and have to be considered with Wheel choices. Quote Link to comment Share on other sites More sharing options...
