l would rather not higher the car..

Yes of course they will. the concept of putting larger wheels on the vehicle is countered by reducing the size of the tire. You may be familiar with the term ''low profile''? Well that is exactly what is done, reduce the size & profile of the tire to only take the same size as the previous wheel & tire package. Supposing u had a (faked for example here) 205/60/16. This represents ur current set-up: 205 tread width, 60 side profile height, & 16 inch wheel. You would then increase width, reduce profile, & increase wheel. Example would then become a 255/40or45/20. Please keep in mind the sizing there is completely fictional & l would recommend taking ur car to someplace like Les Schwab for exactly what ur car is capable of taking.

l would not put 20'' rims on a Mark. The car looks really good with factory chrome wheels or one size up after market, which would be 17''. The suspension is not designed for wheels that big and you will kill the suspension & your ride quality

yup l had some on mine and they looked bad ass
