what do i get by posting if i have a doubt? getting insulted? i think i dont need this. it reminds me of:

I THINK he means that the curve of the wheel at the lip where it meets the tires is different between front and rear.
It isnt', but I THINK that's what he's saying. Like so many of his posts, it's hard to tell.

In any event, you and I gave him what he wants, responses.

 

I agree that is why I stopped posting. To many have arrogant remarks and can be cruel to those of us who were new to this car. So, I just do the best I can to figure out problems on my own.

 

The rear wheels have a wider track than the front, the rear wheels are wider than the front, therefore the outer edges of the rear wheels are farther from the centre line of the car than the fronts. The track width is measured from the centre of the wheel width.
I am ignoring the tires widths as they could vary.
I have no idea if this the answer as I am only guessing what the question was, as the post title has changed, so I guess it not the answer anyway.
