Look up that old thread and verify it yourself. Not many people left on here that are knowledgeable in the 1st gen cars.
Since I can't post URLs yet, I've attached a screenshot of the statement I was referencing earlier, below. Without knowing for sure that what will work on first-generation Intrepid will also work on a '95 Vision, that post doesn't really get me all the way to verification. Are you saying that that's definitely the case? In this situation, what goes for his car will also go for mine?
If you doubt the "mechanic"...measure yourself. The tires you'd like are .7" wider than what you have. Divide that by 2 to get .35" wider on one side. Jack up your car and turn the wheel and see what clearance you have between your current tire/wheel and the strut spring seat. If you can't do that yourself...have someone else do it. Sounds like your "mechanic" buddy is a putz if he didn't even look/measure.
The math was easy enough to work out for myself earlier, and it seemed that there's enough space while the car is sitting still for them to fit in there. I'd just assumed that there was more to the story than how they fit in a stationary vehicle. I figured there would be a certain degree of flex under various circumstances, which may make the tiny gap that would be left over less than ideal when actually driving the car. Hence, my hope of getting information from someone who'd actually done what I'm looking to do.
The "mechanic" sure didn't impress me much. While he made it a point to tell me that, if I did get the tires and bring them to him for installation, he'd charge me to take them off their old rims, charge me to mount them on my car, and if they did end up rubbing, he'd charge me all over again to undo the process and reinstall my old tires - but didn't seem to see any value in getting up and actually looking at the car. He also wouldn't get up off his ass to check out my sunroof issue. Apparently, he just doesn't like money quite enough to justify working on a sunroof, which he hates doing.
