Conserve mode: Need new tires!

[RivianNE]

So what i am hearing is we should conserve the use of conserve mode?

Unfortunately, EV tires still have a ways to go in terms of treadlife. The combination of weight (EVs are definitely plus sized) and acceleration is the death knell for treadwear.

Folks on here have reported that RIvian has suggested only using conserve when you absolutely need it - like road trips where you are trying to get yourself to the next charger.

Unfortunately, getting additional range from conserve can be addicting.

Wouldn't it be great if Rivian could push an update to have power come from either the front two wheels or the rear two wheels in an alternating way so you could at least have more even wear on the tread.

Interesting idea, that would even the tires’ tread life.

Doesn't conserve mode physically disconnect the motors from the wheels and therefore reduces drag. I guess that is the reason you cannot switch at highway speeds.

Regarding the tire wear, now you just have the front tires that provide acceleration and they have to basically get double the weight moving as the rears are no longer contributing, therefore causing greater tire wear. Having a heavy right foot probably doesn't help.

Heavy right foot?

Who, me??????

Yeah - I'm thinking with a motor controlling each wheel, couldn't they effectively modulate power to the front and rear axles making the vehicle effectively front or rear wheel drive?

Seems like that could be worked out in software.

My understanding is all 4 motors are the same so why can't converse mode have a selector so you can specify if you want front wheel drive or rear wheel drive?

Plus rear wheel drive would give someone a quiet mode since the motors are all the way in the back.

The physical disconnects only exist on the rear. There is no way to not-power the front motors. This was a design/cost choice Rivian made.

Is there an explanation of why conserve mode is so bad on tires?

Why is it any different than a front wheel drive vehicle? Sure I get that its a heavy vehicle, but conserve mode is likely mostly used for trips.

It's also not like conserve mode gives you enough power to do burnouts.

Was the OP seriously supposed to rotate their tires every 2 months.

I can’t think of any other 7,000 lbs front wheel drive vehicle. also, adjustable suspension.

umm I only switch to conserve mode once I’m up to 70 and before I engage cruise. Should I not be doing that?

Same, I only go into Conserve mode once at highway speeds.

I am basing my statement on this previous thread. Personally, I have never used conserve mode.

You got me thinking if such a thing exists, and then I remembered the GMC Motorhome from the ‘70s. Front wheel drive, even heavier, and with an adjustable (rear-only) suspension, but it produced substantially less power and not a fair comparison since in a different category.

Same. Once I am stable on the Highway at speed 75+mph, then I switch to conserve mode and engage the Driver+. When I am nearing my exit I go back to All Purpose before exiting.

The rear motors have a mechanical disconnect “clutch” that disconnect the motors from the axles in conserve mode. This does not exist on the front, by design.

Weight and horsepower/torque is why it is different from other front wheel drive vehicles.

I'm usually in All Purpose and occasionally Sport. I replaced the two front tires at 11k, but moved the rear to the front, and then replaced those two at 15.5k... It seems to get even wear I'm going to have to rotate every 2-3k miles.

You say that but the new dual motor is front wheel drive in all purpose unless you accelerate hard enough to engage the rear motor.
