Fitting 325/60/18's on a 2020 Silverado?

[baethye]

Hey guys, long time lurker but first post. I searched first and did not find any results, I know how onerous it is to have the same question asked all the time lol

 

I have a 2020 Silverado 1500 Z-71 Crew cab that has a 2" leveling kit on the front. I found 4 new Nitto Terra Grapplers for an insane deal that I couldnt pass up. 

The tires are 325/60/18 or 33X13X18 and I'm wondering what my best option will be going forward to get these on the truck as I would guess with such a wide tire I am going to have some pretty good rubbing when turning? I plan on running these on the stock 18" wheels. If I could get away with wheel spacers and my existing leveling kit that would be ideal. I do use my truck quite a bit for towing so if I can get away with not lifting it that would be preferred but if I have to thats just the nature of the beast. 

 

Thanks for any input!
