I have searched this and the tire section and haven't found a reference to this. Has anyone changed tire sizes from stock 285/30R20 and 305/30R20 to 285/35R20 and 305/35R20 on their ZL1? I can't find a non summer only tire in the stock size, but can in the 35 aspect. That will close the wheel gap 0.6" so rubbing shouldn't be an issue. I appreciate everyones feedback.

+1 I am trying to do the same thing. I havent been able to find anything definitive on here. I already have a set of 285 35 20 from my 1le that I would like to run on the front so from what I understand I would be best off running a 35 aspect in the rear to not mess with the nannies. I have read on the 2ss's that for some a 305 35 rubs and for others they had no rubbing. Most have said that they have at least relocated the wire harness on the rear drivers side. If you go over to the wheels section there is some info there but I dont think any specific to the 2017 ZL1. I did read that one guy went to a 295 35 and had no rubbing at all but I would prefer to go with a 305 if possible.

The Pirelli Winter SottoZero 3 on TireRack come in both of the stock sizes. They are "Performance Winter/Snow tires."

You know my son...I have the Pirelli Winter SottoZero III, on my 2SS, and they are Fantastic. Like Icyrain said, they have them in ZL1 sizes, which I will also get for my Z.
