The Tesla service manager told me I MUST use their wheels and tires as I look for a 2nd set of wheels and tires for Colorado winters. Is that true? In the end, I'm looking for a 3rd party Tesla focused wheel and tire dealer in Denver that I can source wheels, tires and install. Any help would be greatly appreciated as I can't wait till Dec. 1 for a 2nd set when we all know Colorado doesn't wait that long for the first real snow fall(s).
