Need Experienced Advice Regarding Wheels/Tires

Looking to pull the trigger on some new wheels and tires, but I'm inexperienced in the world of being non-stock. To note, I have a 3" lift from rough country (I now hate extreme terrain's customer service but love rough country's btw) on my '16 TRD Sport.

For wheels: looking at the KMC KM718 Summits, 17x8.5 00mm offset
For tires, either:

• Cooper Discoverer Rugged Trek, 265/70r17
• Cooper Discoverer AT3 LT, 275/70r17

I'd prefer the latter, but I'm afraid it won't quite fit. That's where I'd be grateful for any tips/advice from you all. Thanks

 

welcome aboard!
