Ridiculous is in the eye of the beholder.
The maximum tire width which will fit on the stock suspension depends upon the width and offset of your wheels. I have no experience with 88s, but on the pre-88 models a 255/40 tires on a 17" x 8" wheel with +35mm offset leaves about a finger width of room between the inner sidewall and the strut. No issues at all with 225/45 (same wheel) on the front.
