what is 55-17
215 55R 17
No, only use 17 inch tires on 17 inch wheels.
The owner's manual of your car will tell you which sizes of tires may be used.
Yes, you can
The 2005 Mitsubishi Lancer came standard with 215 65R 16 tires. The automobile manufacture offered 225 65R 17 tires as an option.
Not without changing the wheels also. If you also change the wheels to 17 inch wheels then that is an acceptable swap.
SIZE TIRES, that You can fit on: 14" rims: 235/60/14 15" rims: 215/60/15 16" rims: 225/50/16 17" rims: 235/45/17
It depends on what wheels your cougar came with. If you have the 15 inch, six spoke fan blade wheels, you need 205/60 tires, if you have the 16 inch, sport package wheels, you need the harder to find, 215/50 tires. 17 inch wheels were not available in '99 to the best of my knowledge. If you have trouble finding the 215/50/16 tires, both the more common 225/50 tires, and the 215/55 tires can be used without much problem.
Yes you can put 205 40 17 on the front matched with 215 40 17 on the rear
