Hello all,
My 2016 MCS F55 4 door came with the 195/55/16 tires and wheels. I would like to know what other options I have for sizes that will fit the car without issues. Is there a chart or posting that might have this info? Thank you

 

Tire Rack or Discount Tire are probably the easiest places to find alternate sizes .

 

Factory wheel/tire sizes are 195/55R16 with a 6 1/2" x 16 ET 54 wheel
205/45R17 with a 7" x 17 ET 54 wheel
205/40R18 with a 7" x 18 ET 54 wheel

These will clear the front struts, a wider tire on a factory wheel will get too close to the struts without wheel spacers

 

Keeping your same OEM wheels, you can step up to a 205/55-16 tire and get a little bit extra contact with the road

 

This will also slightly soften the ride, which is nice.

- But no free lunch: Going wider on the same rim width makes the tire's sidewalls more flexible, and you WILL notice this in tight, sporty turns.
I can say this with certainty, having gone from 205mm to 215mm on my 17x7" wheels. (You're also adding at least 1 pound of unsprung weight per tire.)

I definitely don't like the trade-off, and will possibly go back to 205's at some point, using good spacers to get a similar aesthetic.
