Is this size tire to large? 245/60R18 TIRES
Hi oneill_sel. :wavey: Are we talking about a tire that size for a Fusion/Milan/MKZ? If you are, well this is my opinion, and as they say opinions are like...
Yes, the sidewall will be much too large. It will look like a truck tire on your car.
Look at it this way, if you have the stock 225/50R17, your sidewall is 50% the height of the tread width. So 50% of 225 is 112.5 mm.
You will be putting on a tire who's side wall height will be 60% of the tread width. So 60% of 245 is 147 mm. So your sidewall will be 34.5 mm taller X 2 (sidewalls) = a tire 69mm larger in diameter than stock. In other words 6.9 cm taller than stock. That is almost 2 3/4 inches
Traditionally, if you go up one wheel size (say from 17" to 18"), you go down one aspect ratio size, not up two (50 to 60).
As you can see, it will look rather silly (again, in my opinion).
On top of the way it will look, your speedometer and odometer calibrations will be thrown off, reading lower than your actual speed/distance.
And just to make it the triple whammy, I am not 100% sure, but you may run into fit problems.
I would call someplace like "The Tire Rack", "Discount Tire" etc, before purchasing a tire/wheel combo like that for your car.
