Snow Mode instead of All Purpose for more even tire wear

[jaredm]

It was demo'd in one of Kyle's videos. I think it was the factory tour video about a month ago. Software was in testing so I expect it soon.

It looks like the current AP will become Conserve, and the vehicle will start up in Conserve if not driven for 4 hours. Conserve mode will probably default to auto ride height as AP did before, to meet EPA.

The new AP will have memory like the Tri/Quads, so turning off auto ride height in AP will persist. But you'll have to switch to AP at least the first drive of the day, depending on how much you drive.

It's better than what we have today but it's not perfect (I want it to always start in AP, but whatever)

You likely need an alignment. FWD cars do not wear that differently and they only use their front wheels for propulsion. We have an EV which mostly uses the rear tires for propulsion, but the front motor kicks in when needed and the wear is even. We always align our wheels out the gate, though. Wear is pretty even.

Aligning and rotating tires is probably the easiest solution.

You're stating the opposite. The front motor is always engaged the rear motor engages when needed in All Purpose mode. Take a look at the screen and it should show you

I got 41,000 on my factory 21 inch tires. But I have a 2022 quad R1T and drive 90% of the time in all purpose with auto ride height. I rotated every 10,000 miles or so. As others have said an alignment may be needed. The current tires are looking like I should get about the same with this set. At 67,000 and they look good yet.

Your data definitely is like a unicorn. Almost everyone I know with a Rivian, including mine 24 Dual R1T even at 10.4K miles the read is down to 6/32nd. Even wear because I have done 2 rotations so far at 5K and 10K miles.

No. That’s not how my EV works or my ICE. It was just a statement about RWD cars. Whether RWD or FWD, most people will see front tires wear faster than rear ones unless they drive like a maniac.

Sorry what EV do you have? I assumed we're talking about Rivian on the rivian forum

Yea sounds like more double speak from them just shuffling settings around to make it feel like they fixed it. We can already put it Sport or other drive modes and stability settings for 4 hours. Except Rally that constantly nags about wanting to be in another mode.

Well, I've now had three different RWD EVs. I don't drive like a maniac. On all three, my rear tires would wear faster than my front.

On my Rivian, I have about 1/3 of my 30,000ish miles towing, so enforced AWD, but with more load on the rear. About another 1/3 of my miles have been in Conserve, putting a lot more wear on the front tires. (Since Rivian in Conserve becomes FWD.) Between all that, my tires have about even wear all the way around. (And still have 7-8/32nd on all four, having only been rotated once about 10,000 miles ago.)

We have a first generation R1S with 15,000 miles, with 21" Pirelli Scorpion road tires (what's probably now called "Range" - neither Sport nor All Terrain). Hadn't rotated the tires yet. Inspection revealed the front tires are ready for replacement (only ~3mm tread left); rear tires are fine for at least another 15,000 miles.

In the vehicle screen (the drive train icon) it's very clear, as others are posted, that ~90% of the general purpose, paved road acceleration and braking (not hard in either case) is using almost all front motor. Thus the very uneven tire wear. When switching to snow mode (which Rivian says is not for off roading, is specifically for road and highway driving), general purpose acceleration and braking are evenly distributed front/rear. Regen seems the same (plus we can still set it).

95% of our driving is dry paved roads. We're thinking of using snow mode for all of that. We'll trade slightly less acceleration for having to rotate or replace tires every six months.

Anyone else tried this or have thoughts?
Thanks

Range? The 21" option was "standard", discontinued with introduction of gen 2. IMO, there's no need to get clever with drive modes. Better to monitor wear and not neglect tire rotation schedule. In any car, and any wheeled vehicle (including those with 2 wheels), more of the stopping force is at the front, because when you decelerate, weight is shifted forward. This is why all cars have bigger front brakes than rear. Driving a lot in lower than standard height will also contribute to and hasten uneven wear.
