Hey guys, I know this is the place to ask........ I just bought my 2019 Tahoe Premier a couple months ago, but am already thinking about getting ready for the dreaded winter months here in Canada. My truck has the standard 20 inch rims and standard brakes..... I cannot find anywhere what size the rotors are, and the big question is, can I put 17 inch rims on this truck or do I have to go to 18's for winter? I have to have winter tires as it is a requirement here and I would never be on all seasons, they just don't cut it, and I do not want to use my chrome rims in winter.....a good buddy who is a top drawer mechanic at work, said if I went to a slightly smaller rim and a higher aspect ratio tire it will amount to the same thing and is a bit of a cost saving...... so can I use a new 17 inch rim or do I have to go to 18's as a minimum?
