Five year old article on the "15 inch tire problem"

Unless cars start coming with 15” rims again, you will only see tire availability for 15” rims decrease. Like has been said, not hard to figure out. Current car production doesn’t have much, if anything, in the way of 15” rims. Certainly not with anything wider than 225 unless it’s a truck, and even then not much. So yeah, there just isn’t the demand to justify making that many sizes. And it will get worse, not better. BFG and Cooper only have options because they’re filling the demand for every single muscle car era classic there is. As that continues to wane, your only option will be Coker.
