Replacing my Chunking Pirelli Scorpio Rivian Tires with the Michelin Defender LTX M/S

Ever since I got my R1S, I've noticed that the battery range estimation hasn't been the best. Driving a Tesla for the last 3 years, it never had this kind of issue. During my last trip, the driver display shows 255mi remaining. My total trip (including 2 destinations) is 160mi so I believed I should be able to make it easily with a nice cushion. But the center display showed that I would arrive at first destination with 4mi remaining, and run out before the second destination! I knew this was false so I made the drive anyway, and arrived at second destination with 50mi remaining. If I understand correctly, the driver display range is simply the total rated range multiplied by SOC. That makes sense here, since my vehicle is rated for 370mi, 255mi is 68.9%. Coming from Tesla, I expect the number shown in the center display should account for factors like elevation, wind, traffic speed, etc. It's sad that my own mental estimation is better than Rivian's.

Earlier this week, I droped a thread about my chunking Pirelli Scorpio tires. So on Wednesday, I had them swapped for the Michelin Defender LTX M/S 2 tires and the ride has dramatically never been better.

Like some owners might have noted, the Pirellis after 15k miles had become unbearably loud (for me anyway). I mostly drive on the highway and don’t really do any dedicated off road driving.

These are silent, 70k mile warranty, and from what I understand are quite capable for an all-season tire. Just wanted to share in case anyone else was thinking of swapping their tires for something more comfortable on the road.

Cheers
