Just bought these, think they will fit?

You'll be OK with offset, bolt pattern and width, but might have issues with the tires rubbing the strut plate in the rear depending on what size tires you get. It's strange - some non-LTZ's have issues with 18's and some don't - I don't think we ever really figured out why. But if you need to buy new tires, then you can plan for this with the tire height - just make sure that the overall size (wheel + tire) is the same height as your current wheel+tire height and you should be fine (there are "calculators" on-line to determine this stuff).

I had similar spec wheels on my LT I had. They fit but the back tire was close to rubbing the strut. Never had any rubbing issues. If you encounter a issue with rubbing you could try using a spacer.

I have been eyeballing those GWGs in 20"... Our stock wheels have a 48mm offset so with those being a +40 this will help with potential clearance issues. I would say to put a 245/45-18 size tire over the stock size 235/50-18 to make full use of the wheel and the upgrade. If you need more room a 5mm spacer will push you out to +35 and should be right there at the fender lips. Definitely don't want to go beyond that.

Edit - Make sure you buy the install kit with the hub rings. You will need the rings to prevent vibrations. I believe the hub measurement on our cars are 70.3 and those wheels are slightly bigger. The rings will make up that difference and keep the wheel "centered" to the hub.
