What is the standard stock wheel size in a 2017 1LT? (diameter, width and offset)
Tire wall says 245/45ZR18, Standard Rim: 8J
So I'm pretty sure I need a 18x8 rim if I want to stick with this tire size?
What is the (stock) offset?

This will give you all the wheel information you need: https://www.wheel-size.com/size/chevrolet/camaro/2017/. Click on the calculator, then the link icon to see all the details (offset, backspace, scrub radius etc).

I believe your tires should be 245/50ZR18, by the way, unless your car has either the 1LE or the RS package.

I'm confused. Mine is a 2017 1LT. As far as I know, no RS or LE package. Bought it pre-owned from a Chevy dealer. Could they have changed the wheels and tires? Or put smaller tires on?

No idea what your dealer did, but I had a 2018 2LT, non-RS, non-1LE, standard wheel/tire setup, and it definitely had 50 aspect ratio tires, check this (old) picture below.

Nothing changed between 2017 and 2018 in terms of wheel and tire options apart from the 50th anniversary edition being no longer on offer after MY 2017, and also see the 2018 order book excerpt below that specs these tires at 245/50R18 (not ZR, I was wrong there).

With all that said, if you have the wheels shown in my photo, you should be fine with 8.5" wide, 18" aftermarket wheels if that's what you're planning to switch to, just check the offset at the site I linked (it's 32 mm, I think, but please double-check) and don't stray very far from that.

All you said make sense. Thank you. I have the same wheels and I see the R0H code in my RPO plate too.

You're welcome, good luck with your new wheels

(BTW you can also go up to 19" or 20" wheels and get tires with less sidewall if you want, it's the total diameter and offset that matters. Then again, this is a more complex question, I'm not suggesting you should as there will be drawbacks, just saying you aren't confined to 18" wheels just because the car came with those from the factory.)
