Stock Wheel Specs?

[Danner]

I would like to get a second set of wheels for my 2007 Tahoe, used for LT tires when towing. These will be 265/70/17, just like the OEM tires.

What wheels offset do I need to get, to match the OEM wheel set-up exactly?

I can't seem to google it or find it at Chevy.com

BTW> I'm looking for black steel wheels, like the GM police wheels, of NASCAR style. Any soruces?

BTW2> Do earlier year Chevy Tahoe wheels fit the 2007? What about 1500 p/u wheels?

Thanks a bunch.

I have tried with no results to find info on my wheels so many times. Sometimes you gotta pull one off and use your tape measure. Wanna calculate your offset?
1. Measure the wheel width, edge to edge. Let's say it's an 8" wheel but this measurement might be 8.25". Use this because it is your reference to find the centerline.
2. Centerline will be at 4.125"
3. Measure backspace (from backing plate to outermost edge on inside of wheel, same point used before.) Let's say it is 3", since it is less than 4.125" it is "negative" offset, if it was more than 4.125" it would be "positive" offset. Subtract your measurements backspace minus half-width. This formula will automatically tell you if it's negative or positive. So 3" minus 4.125" = -1.125". See the negative?
4. Find an online convertor to convert the inches to millimeters. In this case 1.125" is equal to 28.575 mm. Don't know if it rounds up or down, but it doesn't matter much really.

So in this case you have a negative offset of 28 mm. Remember that the width must be the same, and the backspace will be automatically the same too.

* This is just fun stuff I do in my head, if anyone sees a mistake or something backwards, feel free to say so. But I think it's right. Also I believe that when you take the mystery out it forces the "experts" to be more reasonable in their pricing and assistance.

The stock OEM wheel is 31mm positive offset and 6" of backspace with a rim width of 8".The offset should be stamped into the metal on the inside of the rim.

You don't have to stick strictly to the OEM specs but it's a good idea to stay as close to it as possible. For example my after market rims were 9" wide with a 28mm positive offset and a 6 1/8" backspace and they fit just fine.

You can probably find some takeoffs for pretty cheap, that way you have the exact same wheel.
