Lincoln in essence a 8" wheel is 9" and with a 235 tyre there ia not alot of room left on the inside so anymore would be asking for trouble imo.. Iv got 8" on the front and wont be able 2 run anything more than a 215/40 as thats catching the bodykit and is only 3-4mm from the koni cup. Thats et35.. For some reason each car varies when it comes to wheel width i know of a few guys that run the same et and tyre as mine and dont catch where mine and a few do.
