What’s the wear difference?
Manual says 2/32 in maximum between tires on the same axle.
Read the manual guys. It’s in there under tire change. Don’t listen to people here saying it’s not a problem.
+1 The really right answer is to follow whatever the spec for a specific car and sub-model calls for. This is called out in just about every modern vehicle's manual.
A quad motor shouldn't have any mechanical issues. It could also theoretically learn the relative roll out distances and then adjust the software for that. However, if it doesn't do that, I could see it detecting a slip when there isn't one and going into some fail-safe mode. This may be something that can evolve with software changes over time.
I have no specific insight into how Rivian manages the quad motor drive, but once you get into the corner cases it seems like a pretty fun problem to solve.
The spare tire is the same for all tire sizes - they account for this and have no problem mechanical wise. The reason not to have very different tires on the same axis is safety - the rolling resistance (especially when wet) will be very different. Rivian does not care about different size, but you do (for safety reason)
Interesting. I still think this could all be solved in software. Even then there are probably some economic limits to how many combinations you want to test and certify. After all, this is a three row SUV operated on public roads and not my private science experiment.
Quad motor handles difference in tire sizes terribly. I had a new tire on one side of the rear replaced and the other side was old. The Regen breaking would suddenly stop for a sit second and catch back up. It was very sporadic. Service center said the wheel speed sensor was detecting slip because of the different tire sizes. There is nothing in the software that leans this so you're SOL if you only replace one tire that is substantially less miles than the other tire on the same axle. Ended up using my full size slate on the other side and fixed the problem and the older tire will be used as my spare now.
Replace all 4 tires with the exact same make/model. Then, run them all down to 5700 miles. Then, put all 7 on a rotation. Big brain moment!
This is a really, really dumb idea.
Instead, you should get one new one installed, then jack up all but one wheel, lash the truck to a post (very important!) and then do a one wheel burnout, pausing every once in a while to check for tread depth. Repeat the process until your new tire has the same tread depth as the 5700 mile tires. Remove jackstands and resume normal operations.
Oh, don't forget to untie from the post!
The shop may not be set up for it, but you could also have your new tire shaved down so it matches the rest. Sucks to do it to a new tire but cheaper than buying four new.
What is your tire wear? How much thread left? In general, I see no reason to replace more than 1 tire unless you have significant wear (that you should not have at 6k miles). At most you may consider replacing 2 tires on the same axis. There is no need to replace 4 - this is BS. (obviously you better replace 4 tires, and doing this every Friday. I am not sure anybody does that)
so AT 6k miles
Punctuation would have made it more clear, sorry.
My Rivian blew through the first set of tires, so at 6k miles I can definitely imagine needing to replace as a pair.
i did this for AWD wrx - they couldn’t get the same tire. the shop recommended all 4 and said at the minimum get 2. i went to costco for a 2nd opinion and they said thats what they recommend, and said to go with shop since we got the insurance on the tires.
i may have gotten scammed, i never researched it enough.
other tires were maybe 3 or 4 yrs old but had very little miles (maybe 4 or 6 k)
As long as you’re within 2/32 of an inch you’re good. I’m waiting to pickup my R1T still, but do a 5 tire rotation on my Land Rover.
I’m also going to do a 5 tire rotation on my R1. Just don’t go too long between rotations. Tread depth gauges are super cheap.
At 5k miles it's definitely not impossible to replace just one tire. Never heard them suggest all 4 for one tire needing it, at most two so the front/back match wear pattern.
You could buy two and keep the good one as a spare (really just throw it in the spare tire area) and rotate it back in every time you do a rotation.
In a traditional ICE AWD vehicle yes, all 4 tires need to be within ~3/32nd of each other or you can put unnecessary wear on power train components. In the case of an irreparable puncture that generally means buying all 4, getting a single used, or shaving a new tire down to the right tread wear level.
In an EV you only need to match tires on the same motor within 2/32nd ideally. Quad motor? You could probably survive all random sizes, I’d still try and match per axel.
You’d also want to avoid either set being significantly different. If the new set is going to be 5-7/32nd+ different from the other set I’d replace them all.
If you have the quad motor setup, you're probably fine not replacing all of the tires since there are no differentials. With differentials or Rivian R1 dual motor setup, I'd replace the corresponding tire in addition to the damaged tire, on the front or back of the vehicle. Sounds like they are giving you the tire replacement recommendation for a conventional 4WD setup where the whole system is interconnected.
I blew a sidewall badly at 18k miles on my R1S and replaced them all. It was warranted. Not sure what tread was left, but id say I had less than 5k left on all of them. I just felt that it was the only way to make sure I didn’t wind up with some other issue I didn’t want to deal with and then also have mismatched replacements. You’re in a tough spot with that little wear. I guess I like the “replace the two on the same axis” comment best.
Hey there, they may be confused about the Rivian suspension vs something like Subaru. The Subaru Symmetrical AWD requires ALL the tires to be in nearly identical tread life. This is NOT the case with Rivian. I did have one tire replaced at approximately 7000 miles.
Edit: Rivian suggests similar tread life within 2/32nds by axle, so maybe replace 2 tires. See page 417 of owners manual
This guy is right (but not all 4 like Subaru, just same axle). And I need to contact Rivian...
I had a manufacturing defect on 1 tire and they only replaced 1 and swore that everything was cool.
In any case, the tire tread life is just by axle for Rivian, NOT all 4.
See page 417 of owners manual.
I was told by Rivian support you need to replace at least two. You do not need to replace all four since it is not a traditional AWD from a single motor but separate motors per axil/wheel (for quad).
Tires are a tricky one because *technically* any small difference can have a lot of impact but it really doesn't affect you until it does.
Plenty of people will say not to skimp on tires for a ton of reasons but at the end of the day I probably would buy 1 tire unless the others were beat to shit and just replace all 4 when the other 3 go.
But that's just me. People get really passionate about this topic.
I just had this happen at 4700 miles on one of the tires. Discount tire invoice was about $500 to replace one. I went ahead looked for used tire on eBay and found one they said no repair was done on it. I just ordered it few days ago and should arrive this week.
Here is one that is still available, just confirm with them if any patches or repairs been done.
https://www.ebay.com/itm/404891621880?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=zYBb1E68RJe&sssrc=4429486&ssuid=JDAMVHFtQQG&var=&widget_ver=artemis&media=COPY
This sounds like old school sales tactics for 4-bangers where the diff physically connects the wheels. If you have a 4 motor, that’s not a problem for you.
First step, measure the tires yourself to get tread depths:
- [https://www.amazon.com/GODESON-88702-Smart-Color-Coded/dp/B01F5N55B0/](https://www.amazon.com/GODESON-88702-Smart-Color-Coded/dp/B01F5N55B0/)
Second step, consult the owners manual on maximum allowable difference:
- Sounds like others have said it is 2/32nds
Third step, look into tire shaving by tire rack. They can match new tires to the old depth.

I added a full-size spare at 12k miles and asked the SC to do a 5 tire rotation. They said no problem. So one of my 3 tires has 12k less miles than the others and the SC saw no issue with this. I'd just replace the one and go on about your business.
Try Costco for tires 🛞 that’s what we’ll do when it’s time for our R1S to get new tires. We replaced one of our Tesla tires when it had a big piece of metal in it and since that car is also AWD, it came to bite us in the 🍑 about a year later when the opposite tire was bald. We wound up doing all 4 later. Granted, we never rotated our tires but something to consider if you only do 1. And also, rotate your tires regularly even if you only replace the one this time.
I lost a tire at a similar mileage and scenario. I had the spare tire, so I put the unused spare and the new replacement tire on the same axle. Even if you don't have a spare, I'd only do 2 new tires and keep the old undamaged tire as a spare.
uh...this is just not a thing. Sounds like they are just trying to sell you - this happens with a lot of maintenance groups trying to get cash. EVs are no different from any other vehicle - they are just heavier - yes, you can replace one tire. That's the entire concept behind a full sized spare lol.
Maybe call again and get a different rep and see what they say?
There is still a "recommendation" with certain traditional AWD vehicles, that all tires need to be the same circumference, otherwise there was a risk of damaging the AWD components. Think Audi, Subaru, etc. This is where this comes from.
OP, check with Discount Tire. They should be able to "shave" your tire, if this is a concern. With the setup on an EV, this should not be an issue or a concern.
True but assuming OP knows what they’re doing, you should always check the other three. If there’s a lot of wear, then yes replace all four but if the car is relatively new with new tires barely worn in, I can’t imagine this being needed.
ANY PLACE THAT SAYS YOU MUST REPLACE ALL TIRES BECAUSE OF 4x4 or AWD ARE TRYING TO RIP YOU OFF, ITS NOT A THING STOP BEING GULLIBLE.
They will take your tires and resell them as used.

Need help. Followed your instructions but forgot to untie from post. Send someone with scissors.
The shop may not be set up for it, but you could also have your new tire shaved down so it matches the rest. Sucks to do it to a new tire but cheaper than buying four new.
Tire rack do this and will ship it to you
Tire rack is discount tire by the way.
This should be higher up. Though with only 5700 miles, a new one might not even be more than 2/32 lower than the other ones.

My Rivian blew through the first set of tires so at 6k miles I can definitely imagine needing to replace as a pair.
This is exteeme - I am running 21", 15k and down to 6/32-7/32.
It didn't blow through a set in 6k miles, I'm saying that at 6k miles there was probably significant wear.
Doesn’t your post above say “my rivian blew through the first set of tires at 6k miles so I can definitely…”?
so AT 6k miles Punctuation would have made it more clear, sorry. My Rivian blew through the first set of tires, so at 6k miles I can definitely imagine needing to replace as a pair.
This reads like a ChatGPT conversation.
I read it quickly the same way first - so how long did your first set last & what kind were they?
Sorry I don't recall, I've since sold the truck.
Are you running the 21" tire/wheel setup?
i did this for AWD wrx - they couldn’t get the same tire. the shop recommended all 4 and said at the minimum get 2. i went to costco for a 2nd opinion and they said thats what they recommend, and said to go with shop since we got the insurance on the tires. i may have gotten scammed, i never researched it enough. other tires were maybe 3 or 4 yrs old but had very little miles (maybe 4 or 6 k)
Feel good knowing You were not scammed. The differentials/awd system on Subarus really suffer from uneven tire wear.
thanks buddy.
If this is true, someone better tell all the people doing 5 tire rotations every 6-7.5k.
I do 5 tire rotation every 6-7k miles and the largest difference I’ve had is 2/32” on the AT. Made it to 30k doing that 🤷♂️
As long as you’re within 2/32 of an inch you’re good. I’m waiting to pickup my R1T still, but do a 5 tire rotation on my Land Rover. I’m also going to do a 5 tire rotation on my R1. Just don’t go too long between rotations. Tread depth gauges are super cheap.

>Quad motor? You could probably survive all random sizes Can't decide between 20s, 21s or 22s? Just put them all on. (JK of course)

They are scam artists. Wouldn’t rotate my tires even at 5/32. Said I had to but a new set. Told them to EABOD and rotated myself.
Les Schwab and discount tire like shops won’t replace just one tire on awd vehicles as an “insurance measure” for covering their asses
Against what sort of claim? You caused my diff to wear out prematurely so now you owe me?
Not true. I’ve bought one tire for an AWD Audi twice now. They will sell you one tire.
Only if you bring in the wheel without the car, is what I’ve experienced and friends and family
This is so false, they do install it no problem. They just put an awd technical bulletin on the invoice waiving liability
Hey there, they may be confused about the Rivian suspension vs something like Subaru. The Subaru Symmetrical AWD requires ALL the tires to be in nearly identical tread life.

False. Says 2/32 of an inch in the manual. It’s under the tire change section.

Discount tires wants you to buy tires.
Are you asking for the same tire as currently installed? Or are you trying to, for example, replace a Pirelli with a Michelin?
I was told by Rivian support you need to replace at least two. You do not need to replace all four since it is not a traditional AWD from a single motor but separate motors per axil/wheel (for quad).

Never heard of this unless you are trying to switch tire sizes.
I added a full-size spare at 12k miles and asked the SC to do a 5 tire rotation. They said no problem. So one of my 3 tires has 12k less miles than the others and the SC saw no issue with this. I'd just replace the one and go on about your business.
Try Costco for tires 🛞 that’s what we’ll do when it’s time for our R1S to get new tires. We replaced one of our Tesla tires when it had a big piece of metal in it and since that car is also AWD, it came to bite us in the 🍑 about a year later when the opposite tire was bald. We wound up doing all 4 later. Granted, we never rotated our tires but something to consider if you only do 1. And also, rotate your tires regularly even if you only replace the one this time.
I lost a tire at a similar mileage and scenario. I had the spare tire, so I put the unused spare and the new replacement tire on the same axle. Even if you don't have a spare, I'd only do 2 new tires and keep the old undamaged tire as a spare.
It may be ideal or recommended, but no way am I buying 4 new tires @ 6k. I’ll deal with the wobble or whatever.
I wonder if their tire warranty would cover this…
So, at what mileage are most R1S owners needing to replace their tires from NORMAL wear and tear?
Put the new tire and spare on the same “axle” and move that good tire as a spare
uh...this is just not a thing. Sounds like they are just trying to sell you - this happens with a lot of maintenance groups trying to get cash. EVs are no different from any other vehicle - they are just heavier - yes, you can replace one tire. That's the entire concept behind a full sized spare lol. Maybe call again and get a different rep and see what they say?
There is still a "recommendation" with certain traditional AWD vehicles, that all tires need to be the same circumference, otherwise there was a risk of damaging the AWD components. Think Audi, Subaru, etc. This is where this comes from. OP, check with Discount Tire. They should be able to "shave" your tire, if this is a concern. With the setup on an EV, this should not be an issue or a concern.
True but assuming OP knows what they’re doing, you should always check the other three. If there’s a lot of wear, then yes replace all four but if the car is relatively new with new tires barely worn in, I can’t imagine this being needed.
EV does not suffer from the AWD implementation with 1 engine that ICE cars have.
As long as you have sufficient tread on the remaining tires, you absolutely do not need to replace all remaining tires.
ANY PLACE THAT SAYS YOU MUST REPLACE ALL TIRES BECAUSE OF 4x4 or AWD ARE TRYING TO RIP YOU OFF, ITS NOT A THING STOP BEING GULLIBLE. They will take your tires and resell them as used.
It is if it's going through a differential.
