As many of you have read, my new wheel/tire combo ended up not fitting. Even after I did extensive research for the perfect backspacing and tire width.
Well, I broke out the ruler and straight edge and measured the backspacing of the wheels that were sent.
(SEE PIC that I got from GP001s thread)
When I measured this way, I found out that the backspacing is actually 5.75 backspacing rather than the 5.5" that discount tire.com had told me they were. I had to wait until this morning to call them. I get one of their reps on the phone and explain the situation. This is what he told me:
"The wheels you have ARE, INDEED, 5.5" backspacing, but once the factory installs the 1/2" mounting surface and offset is adjusted, it comes out to be closer to 5.75" of backspacing. What you need is a 22mm offset. With this offset, and the 1/2" mounting surface added from the factory, it should give you about 4.65 (or.87 - I dont remember) total backspacing. We will see if we can order some ZERO offset wheels that will give you 4.5" backspacing because they dont have the extra mounting plate on them"
Ok...the good news is, it looks like they will exchange the wheel/tires for what I need. I will probably have to pay shipping...but, hey, thats only $30. bad news is, they think they are going to have to order them and it may take 6 weeks! Good thing my car isnt road worthy...good thing I kept my old wheels and tires too!!
The part that gets me is the explanation on backspacing. When I ordered, they said they had 4.5 and 5.5" backspacing. To me...that means...the distance from the wheel mounting surface to the top of the inner wheel lip (see pic). According to these guys....that is PRIOR to the offset/mounting surface, etc is installed on the wheel from the factory.
has anyone heard of this before? I thought that I was right in the way that I was measuring.
