Anyone know the width and offset of the original Xtreme 18-inch wheels?

I saw an old post that had them at +18 offset. Hmm.... my wheel research is off now... lol

Yeah the information was verified from GM and on the back side of the wheel if memory services me right

I also see the original Extreme tire size was 235/50/18?

If Extreme is 18X8 +28
and Nissan Titan is 18X8 +25 If I run the same tires 235/50/18 I am just about the same?
I have 2wd Z85 2010 Crewcab? I guess the Extreme is dropped a little lower?

Yes, the Titan wheels have been done many time on the Colorados and canyons.

The only thing that needs to be done it open the center bore up a hair to fit.

and the factory Xtreme tire size was 235/50-18; Goodyear Eagle RS-A tire

but does the xtreme sit lower than my Z85 will? If I run 235/50/R18 Titan rim will the tire diameter be smaller than my current stock 215/70/16? to me the current diameter of my tire looks small as it is?

Looks like 2.1% difference.

thanks!! looks like maybe a 245/50/18 would be a closer tire diameter match for me?
