Wow, cool. Yeah, it seems like Drummond Island is off the beaten path a bit. That's where having a large battery pack comes in handy. Also, a 120V outlet can still be pretty nice given enough time when out on the edges of Michigan.

This has been really interesting to see. I'm wondering how the sound quality is effected by putting the seat down for each of these attempts. Is it mitigated by some eq tuning?

For similar problems, I've seen it suggested to use some hydrophobic coating, like car wax or RainX or similar. It might be a decent amount of work to keep it up to date, but it's probably better than nothing. I used it on my model 3 handles to help reduce the chances of getting frozen handles...

I think the main idea is that they're a lot more durable. They imply in their advertising that the lifespan of the tire should be a lot longer. Maybe it's worth it if you tow more. I'm not sure how 80# = 350#. I assume it's an unsprung weight estimation.

I'm trying to think of why the upper control arm would have less forces on it than the lower control arm. They run in parallel. It seems like they should see similar forces. My Lotus Elise has basically the same upper and lower arms for their wishbone suspension, and they both look stronger than...

Would the degradation be worse if the max pack battery was used with the quad motor, because the quads can pull more max power/current? I'm wondering if this is one of the reasons they don't do the max pack battery with the quad motor.

I've been wondering about the pro/cons of winter tires in the winter in SE Michigan because I don't drive to work, and they tend to clear the roads the same day or the next. So, it's usually only risky during the storm or shortly after. Then it's mostly dry and cold. I have had winter tires on...

I guess another explanation is that the right front motor is just after something a little bit warmer in the cooling loop. Does the cooling loop have a separate loop for each thing being cooled, or does it go from one to another sometimes? On my ICE vehicle, I notice the rear left tire gets...

I don't think it's torque steer, I think it's from the camber of the front wheels just following the downhill path of the road. If this is true, you might see more alignment issues with the DM as they wouldn't be able to compensate by running more power in the front right. But you wouldn't be...

It seems just as likely that Rivian is running that motor more to compensate for the crown in the road to make your car go more straight than it otherwise would. If you can find a road where the road tilts left for a long time (probably the left lane on a divided road), then you could see if it...

I was thinking about your situation when I was looking at the Load Index vs Load Range. As you go up the load range (SL, XL, C, E, etc.) they max load pressure increases as well. But it looks like there are two types for E, one has a max load rating at 80 PSI and the other was like 50 PSI. So...

Yes certainly. 113 is high enough to cover the max GAWR, but it's less than what most shops will allow 115/116.

But really how can you tell that's the back and not the front? :P It could just be the rendered the sub trunk and it covered the engine? Or it's a front wheel drive version like the R1 in Conserve.

That makes a lot more sense. I don't have my Rivian yet, but I'm very tempted to run these in the summer, but I never plan on towing: https://www.tirerack.com/tires/tires.jsp?tireMake=Michelin&tireModel=Pilot+Sport+4+SUV&sidewall=Blackwall&partnum=75VR1PS4SUVXL&tab=Specs The slightly smaller...

I had extracted the curb weights from a couple EPA filings here for R1T and R1S. https://www.rivianforums.com/forum/threads/r1-weight-estimate-and-more-for-quad-vs-dual-motors-from-epa-filing.17123/post-365634

Strangely, when I got my Model 3 Performance, they had dropped the price shortly after purchasing by $5k, and people complained and they actually sent out a $5k check. That was nice, and not really required. So, maybe they've got a mixed bag track record.

Well, I prefer to not let the facts get in the way of my reality. JK! I really do remember something that pointed to 116, but maybe I got it backwards and one of the websites said 116 but it's actually 115. Meh. Maybe pointing this out would help with those trying to get 115 load tires? It...

I think someone posted a picture of their tire and it's actually 116. The websites got it wrong. Haha, actually, can you check your tires?

The important GVWR is just the rear axle, aka the GAWR which is 4960 (last I checked). But you could find this on your vehicle. I suspect it doesn't actually matter what the math says, Tire Rack and others just won't mount something less than what the OEM puts on the car, which is 116. But you...

If you watch more of his videos, you can see examples of the cheap tires performing worse than good all season tires at many things. It's often a get what you pay for situation. If you go for the really cheap snow tires, they might be worse than good all season tires in the snow, and way worse...
