Michelin Defender tires installed on 20" wheels

[Taiga]

Any range updates now that you've been driving on them for a while? I know you said 6% loss but how many Kw/mile are you averaging?

FWIW my guide told me in an email that using non OEM tires will void the vehicle warranty.

Does Rivian take a position on people using a non OEM size/brand tire on their R1T?

Yes, this is a safety related issue. Our tires are built to our specs and weight class of the R1, so a lesser tire is a safety concern. This will void your warranty if there is an issue, here's what the warranty states:

Our tires are calibrated by size to work with the drive modes so any variance can cause performance and safety issues. Always use Rivian tires and Service to avoid causing damage and voiding your warranty.

I believe it is against the law to void an entire warranty if the tires meet the manufacturer recommended specs...I guess how close those specs need to be is a question though.

I'm no expert but unless they can trace the issue of whatever happened to the tire itself, assuming it matches minimum spec, I don't think they would have any ground to stand on in the court of law.

I’m considering switching to the Continental Terraincontact h/t in a 275/65/20 for daily driving and keeping the stock pirelli ats on a set of dodge 2363 wheels I picked up for when I do some off-roading.
The continentals weigh 57 apiece and are 126/123s. Should I expect much, if any, of a range increase?

The lack of a recommended winter tire is a big miss and a safety issue. To say using one like a Nokian LT3 that meets all of the vehicle specs will void the warranty is ludicrous.

Sorry for the delay. After the latest test, I’m actually seeing a range increase of about 4-8% when compared to the road tires, which is mostly driving in a mix of AP, Conserve and Snow modes, mostly city/town driving.

Curious what the range would be with these tires and the evsport aero covers

Just to clarify, the "road tires" in this context are your former 21" wheels/tires that came with the truck? If that's the case, then is your range at 100% in conserve mode more than 440 miles? And how does the ride comfort, noise, and vibration with your current wheels/tires compare to the 21" wheels/tires?

Thanks for answering everyone's questions! This post and your responses are really helpful.

I'm sure Rivian is looking for any excuse to cancel warranties

I think it's safe to interpret the warranty comments as: "Rivian will not warranty a third party tire." So if you put on some other tire and it catastrophically fails due to defect (or improper load rating or whatever), they're not going to cover that, or any damage resulting from it. (Whereas the stock tires failing due to defect would be a warranty issue.)

As others have noted, consumer protection law is pretty clear here - they can't blanket void the warranty due to a single modification unless they can demonstrate that the modification caused the specific failure in issue. If you change your tires and battery catches fire, Rivian's still on the hook.

(I am not a lawyer, though I did drop out of law school once.)

I’m also getting ready to pull the trigger on the Scorpion AS Plus 3 in 275/60 R20.

Did you? Any feedback? thanks

After switching from stock 22” wheels to aftermarket 20’s with similar to stock 20” tire size, I think this is a good choice for anyone that prioritizes ride quality over performance or looks. I suspect that the on road performance doesn’t suffer much vs OEM 22’s and is superior to OEM 20” tires. The taller sidewalls improve the ride quality and remove fear of damaging a wheel on a curb or pothole. It’s a lot more fun to drive this way (IMO). For example I don’t slow down for speed bumps & the truck doesn’t miss a beat. I suspect that the vehicle was designed around the 20” wheels & tires.

Not yet. I’ve just crossed 10k with the ATs and have done a second 5 tire rotation. I think I’m going to get 25k out of them. My ATs really have zero resale, so I’m inclined to wear them out then make a one time change to 33” AS3. I may try to source 3 more wheels and have a winter set.

Which tire did you go with that’s similar to stock 20s?
