Wheel help

[Gstick]

Someone PLEASE set me straight on my OEM 17" x 7" 6 spoke alloy wheels. (off of a 2010 SR5 4x4, 4R) I know that the bolt circle is 6 x 139.7 mm or 6 x 5.5". (same thing)

And the backspacing is 4.5"

Now I have read (somewhere) that the offset is 0, but Ultra Wheels (in California) claims that the OEM wheel is a +12 offset. The 17" x 8" wheel that I want has a +5 offset with 4.5" backspacing. I was told that this wheel won't fit. :redbrick:

Also, is the hub diameter the same thing as center bore ?
If these are the same, then I believe my OEM wheel is 108.__ ?

Thanks in advance!

SR5 rims are 17x7 with a 6 x 5.5 bolt pattern and a 4.5 inch backspace.He is correct in that the stock SR5 rim is +12 offset and the Toyota hub diameter is a 106mm. It's a 0 offset if it's a 17x8 rim and 4.5 backspace.

108mm bore on the aftermarket wheels work because the cap usually takes up the other 2mm. At least on my AR Mojave's they do.
