The Tesla All-Weather mats in the back of my car have serious curling issues where they bend around the edges quite severely. I told my Service Center and they told me that that was a common problem and that there was nothing they could do. I even emailed the Tesla Store and they just told me to buy the newly redesigned mats.
TBH I wouldn't really recommend them. Because of the curling, the dirt and grime just falls under the floor mats onto the carpet below.
There was a whole thread about this issue a while back:
Weathertech Tesla Floormats curl up in the back row!
