I'd be happy to bring my car to Bollingbrook, IL if anyone has a Weathertech contact. They might be able to make one faster?I asked my high-up contact about both of these, because I care about them too. No word on all weather floor mats, but pricing for wheels and tires should be finalized in a few weeks, though that says nothing about supply.
The 19s will definitely be available for purchase; it is just a matter of when.
For now, I would recommend the motor trend all weather floor mats and cut them to size (if necessary).
