Conserve mode: Need new tires!

[Goose]

According to Rivian:

Why don’t Dual-Motor AWD and Performance Dual-Motor AWD vehicles have Conserve mode?

Dual-Motor variants use our Automatic AWD drive system. In All-Purpose mode and above about 19 mph (30 kmph), Dual-Motor vehicles are propelled by the front motor and front wheels only. Similarly, a Quad-Motor vehicle in Conserve mode de-couples the rear motors so that only the front motors are in use. Dual-Motor vehicles will decouple the rear axle to maximize range whenever possible. Automatic decoupling and recoupling on demand makes a separate Conserve mode in Dual-Motor vehicles unnecessary.

Automatic AWD in a Dual-Motor vehicle automatically maintains the rear axle coupling during high acceleration or disconnects the rear axle when not in high acceleration. This also helps reduce cases of increased front tire wear as power is more evenly distributed across all four wheels when needed.

I read that too, it’s extremely vague. Who dictates what “high acceleration” is and what point the rear axle engages? Also, for those of us that are gentle on the throttle (accelerator for EV’s?), does that mean it’s hardly ever AWD and would have increased front tire wear?

I would much rather the truck be rear biased rather than front if they’re going to mandate 2wd.

I don’t know. I bought quad. But there are dual motor trucks hitting the streets now so I’m sure we’ll find out how they perform.

So after only 1 year and 18k miles, I already need new front tires. Maybe 50% of that driving was done using conserve mode.

My recommendation, do not use conserve mode unless if you have to. In our situation, conserve mode was the difference between stoping at a 50kw charger vs +100kw or having to add another stop, especially driving through Vermont or upstate NY.

I don’t think I would use it going forward, unless I absolutely have to. I would confess that I often forgot to turn it back to « All purpose » when exiting the highway. My recommendation for Rivian is to create a « Smart Conserve Mode » that only turns off the rear motors if over (maybe) 50mph.

Anyway, hoping my experience will help others.

We love our truck!

Have you rotated the tyres every 5k miles?

2024 Leased R1S Adventure. I left in conserve mode. Didnt get any rebalancing after picked it up - which i hear now was a mistake. At 8.5k miles i took it for rotation and was told front tires have too much wear to make it worthwhile. Now at 12k front right is almost bald. Need 2 new 22' Scorpions as my turn in date is 3/30/27 and dont want any mismatch issues when i turn it in - if that is a thing. Any recommendation on best place to buy / install in Coral Gables / Miami? Thanks.
