What are the best floor mats for the Rivian R1S?

Re: Congrats on the new R1S! Seriously, ignore the generic stuff, 100 percent agree. Over the years I have learned that for vehicles with floor geometry as complex as the Rivian, laser scanning is not just marketing fluff, its a safety requirement. You need high-wall coverage to contain the mud and debris your dogs are dragging in. In my experience, you should look for thermoplastic elastomer (TPE) construction rather than standard rubber because it holds its shape better in extreme temperature fluctuations without off-gassing. Here are two solid options I have tested personally:

• TuxMat Custom Floor Liners Black Full Coverage
• These offer the best cabin coverage, basically acting like a tub for your floors.
• WeatherTech FloorLiner HP Black Laser Measured
• These use a high-friction underside that prevents sliding significantly better than cheap aftermarket alternatives.

Jumping in here because @Reply #3 - good point! Honestly, dont settle for cheap junk. With the R1S, you really need precision. I have been using the TuxMat Custom Car Floor Mats Black and they are absolutely amazing! The coverage is insane because they go way up the sides to catch all that dog mud, and the material feels super premium. If you want something a bit more rugged and utilitarian, check out the WeatherTech FloorLiner DigitalFit Black. Those are the gold standard for durability and they lock into the factory clips perfectly so they never slide around.

• TuxMat for maximum coverage and luxury feel.
• WeatherTech for heavy-duty, industrial-grade mud protection. Either way, just make sure they have the retention hooks. Safety first, always!

Congrats on the new R1S! Seriously, ignore the cheapest stuff you see on marketplace sites because those universal fit mats are a total nightmare. I tried the generic rubber route on my first car and they kept bunching up near the brake pedal, which is honestly terrifying when you're driving. You really need something that uses the factory retention posts to stay locked in place. Since you have dogs, you definitely want something with high walls or channels to catch the mud before it hits your carpet. Just be careful with the glossy plastic stuff because it gets super slick when wet, making it hard for your paws—err, your dogs—to get steady footing.

• Look for deep ridges rather than flat surfaces.
• Make sure the backing has a high-friction material so it doesnt shift.
• Prioritize coverage that goes way up the footwell sides. I would suggest spending a bit more now to avoid a headache later. If you get something that isnt laser-scanned for the R1S floor pan, you will end up with gaps that collect dirt anyway. Take your time searching for reputable fit-specific sets. If you need tips on how to clean them once you get them, just shout. Good luck with the new ride!

Building on the earlier suggestion, honestly just do yourself a favor and buy quality right out of the gate. I remember when I first picked up my vehicle, I tried to save a few bucks with some basic stuff from a hardware store, and it was a massive mistake. The amount of grit that got under the mat and started grinding into the factory carpet was heartbreaking. If you have dogs, you absolutely need something with high walls that locks into the factory mounting points. In my experience, WeatherTech or TuxMat are the gold standards here. You really cant go wrong with either of those. Yeah, they cost a bit more, but they stay exactly where you put them. No bunching, no sliding, and they basically act like a bucket for all the mud and debris your dogs bring in. When things get dirty, I just pull them out, hose them off in the driveway, and they look brand new again. Youre driving a premium machine, so dont cheap out on the one thing that keeps the interior from looking like a swamp after a rainy weekend. Just grab a set from one of those reputable brands and forget about it. Your future self will thank you for not dealing with loose mats sliding around under the pedals.
