Buick wildcat production stopped in 1970! A different site also states this car came with 15" wheels as stock not 14" as your site reads! Where do you get your false info? I have owned my car for 20 yrs and know these facts as such. Why don't you people?
...not sure on what’s the best / biggest / widest / maximum tires or rims will fit your car?
Write about the tires you are currently driving on.
