Issues with Rivian advice vs America tire advice

[godfodder0901]

No. In all purpose, Rivian defaults to FWD unless all four are called for. Fronts wear sooner

This is not true for all Rivians. OG Quads are always Quad in All-Purpose.

This is true and not true at the same time. It is true that the OG Quad is in AWD all the time in all-purpose but if you look at the power distribution its biased to the front. You can see about 20% more power for acceleration and regen goes to the front vs the rears on the quads.

The previous post says it all. Rivians spend a lot more time in FWD than AWD so the better tread should be on the front.

No on the the gen 1 quads. Most people drive in AP or Sport mode, both of which mean you're in AWD. Only conserve is FWD on those vehicles.

My post was referring to traction, specifically at the rear when turning.. I was not referring to tire wear. We all agree that the fronts wear faster on the R1 vehicles, but you still want the best tread on the rear to prevent fishtailing.

Rivian told me to put regeneration mode on low instead of standard or high, in order to maximize tire tread. They told me when you rotate tires to put the newer tire with more tread in the front. I told America tire that, however they declined and stated that they always put newer tires in the rear. Anyone else have this issue or should we force them to do what customer wants? Not sure how that impacts the mileage warranty’s. Don’t want them to say I told you so but you didn’t follow their best practice.

I had the opposite experience... I went 11k miles before my first rotation. Then I changed out my wheels for the winter. The following spring (at the Rivian service center) I asked them to mount the greater tread on the front because I wanted to even out the wear. Rivian tech said they put the more tread on the back as standard practice. I insisted and they did what I wanted, but weird that this Rivian tech would recommend the opposite of what your Rivian guy said.

I still think "more tread" goes on front.

Tires on my R1S are wearing out evenly all around, regen set to whatever the higher setting is, cannot remember.
Tires on my Model S, also AWD and max regen just rotated; all 4 tires wearing out evenly as well.

Many tire stores have policies that's outdated. Costco has the same policy.

The reason for putting the new tires in the rear stems from when all vehicles were RWD. The rear wheels propelled the vehicle forward and needs more traction to accelerate and avoid wheel spin; hence put the new tires on the rear. With FWD, you'd expect to put the new tires onto the front - the driving power wheel.

In the case of Rivian, since its a AWD with a bias towards FWD in conserve or freeway condition in the dual motor, and more regen is done by the front wheels (there is a weight transfer as you slow down to the front so it makes sense - the reason why Rivian told you to put low regen setting is to minimize the tire wear by not slowing down as strongly as the standard or high regen setting).

With the traction control on just about every vehicle, one has to really try intentionally to get into an oversteer (fish tail) situation - like turn off traction control.

We had a Saab 9-8 that needed new front tires (FWD) and Costco insisted putting the new tires on the rear (trailing wheel with no power). The tire tech knew it made no sense but that is the policy. He told me to make an appointment for tire rotation the following week to get the tire onto the front, which we did. It was just added inconvenience.

This is what I've always heard. It's not the tire's location on the vehicle that matters. It's having the best tires on the drive wheels.

For the owners that added Michelin, were you able to add “Michelin” in place of the “Pirelli” in the settings? The setting tracks the tire mileage and rotation reminders.

I’m was not able to add “Michelin” other than generic all terrain. There is a “swap” button but I think that only changes the size of the tires not the brand. It resets the vehicle for some reason.

So what you’re saying is consistent with what america tire is telling me. That’s what I told the Rivian tech when he told me this. He said that is true on non-EV cars but with Rivian and the regen braking, Rivian advises to have newer tires in the front NOT in the rear.

Yes, I just had a tech here and he said they wear faster in the front BUT mine do not?? My back are wearing faster. Tires have 25K on them, I am in high regen, rarely if ever in Conserve mode. Cannot figure out why my back tires are wearing faster?
