This is the best article I've found so far: https://blog.tiremart.com/tire-load-range-and-ply-rating/ I think it implies that the higher load range really is more of an estimated durability. And higher durability means you can run higher pressures in order to get a higher load index. But the...

Thanks. I forgot about that, as I've looked this up before, but ended up very confused. For example, as you said the XL tire's max capacity is 41 or 42 psi, but the max tire pressure is 50 psi. The SL rated tires have max capacity at 35 or 36 psi. So, if you see something that's SL vs XL with...

The 21" and 22" tires are about 33" diameter. The stock 20" tires are about 34" diameter. The 275/60R20 tires are about 33". So, they work well for those coming from 21" or 22", but would be off for those coming from stock 20".

The reason I did the calculation was because it was presumed that the 800V architecture would definitely make it take less time charging on a trip. But, as noted above, it could be very similar. But, as you noted, the Standard Pack is probably more comparable in price and range. And it probably...

One thing that was pointed out on Reddit is that the e-AWD versions are about the same efficiency as the Dual Motor Rivians, but obviously a lot less range, and slightly smaller and probably lighter. So, it turns out they'd get about the same miles added per stop for many people: First, as this...

I should add, I took picture of the electronics that Munro had after they took apart their R1T. I think it had a Qualcomm for one of them. But nothing seemed significant enough to do any higher levels of driver assistance. I could share the picture though.

Does anyone know who provides the hardware and software for Rivian's driving assistance solution?

Cool. It's right next to Holly Ski Resort. And it's a county park: https://www.oakgov.com/community/oakland-county-parks/parks-trails/holly-oaks-orv-park

So, then the received KW at each % of battery should be about the same, it'll just take like 15% longer per percent? Check my math, but I think that means it'll still receive more total kWh as it should be able to continue to receive near peak KW until it starts tapering at the similar...

Sadness. :( My misunderstanding. I wonder if the rate of recharge (C) is any different then.

Someone with a Max Pack should check the charge curve, because it might be higher. If the pack is basically the same but with higher voltage cells, then the cell pack would be like 15% higher KW and the same charge %/time. I bet people could get almost 250KW. What do you think?

I suspect tearing it up 10mph faster around the curves may also impact range. :) Presuming your location, there are a lot of great roads in that area, and I go out of my way to wind my way through it when going anywhere near that area.

I didn't see it in this reporting, but I believe the first EV9's won't be eligible for any of the Tax Rebates from the IRA. I believe the Rivians would be at least eligible for half. That would effect the resulting price accordingly. I personally like the look of the EV9 and I think it's got a...

If you make a reservation early, they'll give you some free things that presumably you'd otherwise have to pay for. So, here's the list of things you'll have to pay for: "Customers who make a reservation request through November 27, 2023 will be eligible to receive a suite of gifts after their...

Just in case this hasn't yet been said, if you're going to try running Load Index 113, you should make sure you're also using max PSI, as it's only rated for that weight when at max PSI.

I don't have any specific sources of range for towing except what people have reported on here. I think there is a thread of people reporting their range when towing. It mostly taught me that I shouldn't plan on towing things. :) But I was asking about the Chevy, Ford and Ram trucks. You...

This is very interesting. I do suspect the DM will be like 4%+ more efficient than the QM when in conserve based on their EPA testing. It might be even better when they get more compared to full time AWD, but they didn't test that for DM. The raw values for QM Conserve vs DM are 331-336 for 21"...

I highly suspect Rivian is trying to keep the number of variations of the vehicle down and just hit the target market. And they assume the target market wants the max range when the select max pack. And the dual motors are still likely a few percent more efficient than the quad in conserve. I...
