The Drive: Why Gen 1 quad devour tires

[Mark_AZR1T]

I’m not buying that explanation. My Gen 1 Launch Edition has over 50,600 miles on my AT tires, plus about another 5K left. It's not about the Bosch motors. It all comes down to Rivian’s inability to consistently deliver proper alignment and suspension from the factory.

I may have just gotten lucky, but to me, it’s clear: tire wear has nothing to do with the motors and everything to do with setup quality.

*and the person driving it. I know why my tires are wearing quick and it’s 100% my fault. I drive the shit out of my tri and did out of my old quad.

TLDR: Relates to amount of control over engagement and disengagement of the Bosch motors at the rear. With Gen 2 in-house motors, there is more control. Thus, allowing them to blend in/out power delivery between the two axles better, to limit tire slip/wear.

I don't buy that explanation. The rear disconnect on the Gen1 is only engaged when you switch to Conserve - either manually or if you have Auto enabled then automatically at a set speed. I don't think the number of times this switch happens for normal use cases could every introduce noticeable wear on the tires, even if it was causing wear.

My Gen1 R1T has OEM 20" tires with 30k on them and still 8/32" all around. I rotate every 7500. That means they still have maybe another 30k left in them. I manually switch to Conserve only when driving on the highway, after getting up to speed.

My Gen1 QM needed tires at 20k miles. I wouldn't call that eating tires.

I made it 37k miles and could've gone more with my 21s

Old is made new again? Deflection is one of the oldest tricks in human history.

After reading through the article, my opinion is that the author didn't understand or chose to dramtize the difference between the Gen1 and Gen2 motors and architecture and how much it affects the Gen 1. Nobody in a Gen1 is switching between All Purpose and Conserve the way the Gen 2 does automatically, but that seems to somehow be a major part of the author's "smoking gun" as to why Gen1 tires wear so much more than Gen2. I think he misinterprested Rivian's comments about that. IMO he's wrong.. I'm at 24K miles and have 1/32 difference front to rear, and I estimate I will get 35K miles out of the factory OEM 20" tires. Give or take, that's what I got on my Avalanche and Suburban. It's all about driving style, alignment and to a lesser degree, road conditions.

But… bear in mind you have the 34.1” factory ATs, with deeper tread than other factory offerings. Not everyone chose the same wheel/tire configuration Complaints of premature wear shouldn’t be alien to regular visitors of this site. I recall ones complaining about worn Verde AS at just 12k miles (though those cases may have more to do with user error of Conserve, or bad alignment, or both). There are multiple factors that amount to accelerated wear. The article touches on some: traction and weight transfer.

I was at 41,000 on my 21's when I replaced them. They were the first set my next ones seem to be lasting as well same Perellis from Rivian. I drive mostly in all purpose with auto for ride height. I do launch very occasionally. I only use conserve on long interstate streches. It does seem to have pretty good alignment which I am sure helps. It is a 22 Quad R1T. Currently 66,000 miles.

I could see the disconnect being why they don't switch between 4 and 2 wheel drive in conserve, but not that it's the cause of wear.

I have 19k mostly city miles, with minimum of 5/32 left on all tires. I use AP standard most of the time. The wear on 21' Pirelli isn't too bad. They should get me 30k miles, which is about the same I get on my car with Pilot Sport As3+. I don't launch from stop, but do use about 75% of the power while getting on the freeway or while passing.

I think the problems were a mix of Conserve mode, aggressive launch from a stop and bad alignment.

hell yes! I was on the phone the other day and passed a car hard. Guy on the other line "What the F are driving a space ship?" didn't realize you could hear that over the phone bluetooth.

I currently have 33k on my gen 1 quad 22” scorpions. I can probably get another 5k out of them. I say probably because 5k ago I was thinking I had 5k left. They seem to wear slower the more worn they get. I drive 50 50 between AP and conserve. Do my own rotations every 5k.

 

[Ecupip]

The main culprit was that everyone was leaving their cars in conserve mode (lowered and FWD) all the time. That, plus driving spiritedly, would wear out the front tires extremely quickly.

I really think it’s driving habits. I have 30k on the oem 20” scorpions. Only reason I’m getting new tires is the unbelievable noise they are making. I do rotate every 7500 miles. Also I try and use conserve on highways when dry. Keep ride height in normal. Getting the Michelin defender LT/X ms2’s this week. Can’t wait for noise reduction
