We have a gravel driveway, and little bits of gravel are often tracked into our cars. I bought the all-weather mats (from Tesla - I'm not familiar with MAXpider) and they have been a perfect solution. As a previous poster mentioned, they fit perfectly. They have a small rim around them, so whereas gravel pieces would collect in the valley where the carpeted mats met the floor, these have no such issues. Any gravel or other debris that makes it into the car stays corralled on the mats where it can be easily removed. They seem very tough and durable, and would, I think, take a lot of abuse to no ill effect. I also got the mats for the back seat, and those have a couple of inches of overlap and velcro together in the center so if someone got in with muddy, snowy feet the carpet would be well protected.
