What are the best all-weather floor mats for the Rivian R1S Dual-Motor?

Congrats on the R1S! Im in CO too and the salt is a total nightmare. I would suggest being careful with older stock since the floorpan might have minor tweaks on the newer builds. You might want to consider:

• WeatherTech FloorLiner Custom Fit for Rivian R1S for a tight seal.
• TuxMat All-Weather Floor Mats for Rivian R1S for max side coverage. Make sure to verify the retention clips work with your specific build tho... sometimes they shift if not locked in.

Tbh, I've been pretty disappointed with how some of the premium brands have handled the R1S floorpan updates lately. Tried a few sets that were supposedly compatible but they just didn't sit flush around the center console of the dual-motor build, which drives me crazy. For Colorado slush, you really need that high-wall protection that doesnt warp when it gets freezing out. Use something with a grippy underside or itll slide.

• 3D MAXpider KAGU Series All-Weather Floor Mats for Rivian R1S are great because the backing grips the carpet like crazy so they never slide under the pedals.
• LinerX Custom Fit Floor Mats for Rivian R1S 7-Seater are made from a heavy-duty TPE that is super rugged but still flexible enough to handle the floor layout.
• Lasfit Custom Fit TPE Floor Mats for Rivian R1S have really solid coverage for the dead pedal area which is where most of the salt ends up. Definitely double check the manufacture date on whatever you buy... the slight tweaks Rivian makes mid-production are a headache. Let me know if you want photos of how they sit!

Reminds me of when my cousins mats slipped under the brake. Total nightmare, but we survived! Safety is everything with these heavy EVs, makes me happy I pay attention to it.
