I believe the load rating is for max tire pressure. That'd be 50 or 51 PSI for most passenger tires. Having a higher load rating allows them to run lower PSI, probably mostly for comfort.

From the announcement page: " Meeting the needs of the growing heavy-duty and luxury pickup truck market, the new Defender LTX Platinum tire will offer six 20” rim sizes with cutting-edge aesthetics and dramatically better treadlife than its competitive set. Featuring a 70,000-mile warranty, the...

It's interesting that on the 22" tires, the tread depth is higher, but the tire warranty is lower. I wonder if they're using the same compound, or if they just expect 22" tires to wear a lot more quickly. Michelin is a top quality tire making and these are important tires for them. So, I would...

The DM is about 121 pounds lighter according to the EPA filing: https://www.rivianforums.com/forum/threads/r1-weight-estimate-and-more-for-quad-vs-dual-motors-from-epa-filing.17123/post-365634

This was my thinking as well. Without the early pricing, it just doesn't make much sense to get the 20" or 22", as with a little work you should be able to get a setup cheaper than the current new upgrade price. It's barely more expensive to get the full set from Rivian than the upcharge from...

That's great! I've been seeing plenty of Dual Motor Rivians in the R1 Shop. So, I think the time is now!

Here are some details I collected from the EPA data: https://www.rivianforums.com/forum/threads/r1-weight-estimate-and-more-for-quad-vs-dual-motors-from-epa-filing.17123/post-365634 The quad is tested with conserve and All Purpose. Dual is just All Purpose because it has a built in Conserve...

We need to get this person side by side with someone of the same spec but quad motor for some real side by side testing. There are too many environmental variables to compare one to another between days and drivers and routes and weather, etc.

I definitely see my tire pressures go up and down with temperature. But, when I check at about the same temperature after many months, I don't tend to see much loss unless I have a hole in my tires. However, throughout the year with the tires that are on the car (I swap with summer/winter), I do...

I heard Nokian was planning on supporting Rivian, but apparently not yet in the 21" size: https://www.nokiantires.com/rivian/

That's an interesting idea. But, I wonder how long that would take. My tires don't tend to lose much air when between swapping them for the seasons when I use my standard type air compressor (the kind with a small air tank). I feel like they lose about 0-?2 psi maybe over about 6 months. That's...

Plenty of auto manufacturers use Ethernet right now. I don't think it's a replacement for the bulk of the low speed CAN busses in use right now. I had it explained to me from someone at Munro and Associates that the major reason Rivian has such a large harness is because they don't use position...

I wonder if they'll try to get the NACS connector included at that point as well.

Also from the article: Rivian "is moving onto a simpler network architecture that reduces the number of parts (mainly ECUs) needed by about 60%. That allows the brand to also shorten the wiring harnesses by around 25%." This clearly coincides with the standard battery pack. I wonder if the...

I haven't seen anything actually confirm that the R1T is more efficient than the R1S. The R1S is lighter and they have the exact same cross section area. The EPA tests are very similar. And I think both the dual motor's are rated the same range now...

I believe this is basically the same behavior that Tesla's have. I haven't really heard of issues with Teslas. But, I know with my Tesla, it accelerates very slowly off the line when using TACC or FSD Beta. I nearly always get a really large gap between me and the normally slow ICE vehicle in...

Just a note, you could align your vehicle at any of the ride heights, but the ones that are farther away from that height would be more out of alignment. So, for people that like Low or Lowest, you could get someone to fix it for that height.

Yeah, the diono seats are really tall. Thankfully my wife is okay with the reduced leg room.

I need to update my comment from before, they did actually run a test at every 5 mph and plotted it on the graph against their theoretical and they didn't match, and chose the theoretical values instead for some reason. The real world values clearly show less range at lower speeds and better...
