Judging by the 265 wide tire and the fact that this is for the Touring model, I'm assuming this is the wider wheel option on the 'top-er' models? maybe 8.5?
Yes, the wheel size is exclusive to the Touring and Elite trim for the 2019-2021 models years, however, the Elite has glossy black finish instead of the metallic gray of the Touring. Both are 20X8.5 inches.
