upgrading wheels and increasing wheel gap?

1306 Views 9 Replies 6 Participants Last post by  IDLOOK2
it is my understanding that when we upgrade to 19s or so, the wheel gap actually increases, and therefore makes our car look like a 4 X 4. Is this not the case?

My friend and I are having a debate. He says when you upsize, it will fill the wheel well up, and you really don't have to lower. I ofcourse disagree, and just with pics of BMWs on 19s alone, they do look raised.

Can ne1 give a technical and good explanation of exactly WHY it gives the car a raised look? I can't quite seem to put my explanation into words.

You're totally wrong. :tongue: Since the outside diameter of the tire is exactly the same as stock, the wheel gap is exactly the same. Unless you go with a tire that is the wrong size, it's a fact.
so, since it's hard to find an exact match of tire with the perfect profile you're lookin for, and most of the time, upgrading rims plus low profile tires will be slightly bigger (my 19s with 235/35 is about an inch bigger than the stock 17s), that would be why it would raise the car then, right??
no Dinan susp...too much $,not enough lowering. (

I decided to go with Eibach/Bilsten combo instead.
