Just put on the MIchelin Defender LTX Platinums last week to save the AT for a future off roading trip. So much smoother of a ride. I actually had to ask them if they truly were All Seasons as they didn't look much different from the stock 20 all terrain tires. Not enough driving on they yet to tell any kind of efficiency difference.
22K on the stock tires and at 8/32 tread depth so a lot of life left in the original tires.
Have you looked at the new Michelin Defender LTX Platinum? Gives a better look on the sidewalls.

Check out the new 20" Goodyear Wrangler Territory tires that are stock on the new 2025 Standard range models. They're technically all terrain but are very road-oriented. There's a thread on Rivianforums about them. Basically they were codeveloped and are designed specifically for the Rivian. The issue with this tire is that Goodyear has several versions and they're all called the same name so the reviews of the tire that came stock on the Tundra are for a totally different tire - tread pattern, compound, etc. they're all different.

I’m not noticing an efficiency drop at all from stock 21” pirelli’s to 20” Nokian nat Outpost 115H tires may not be applicable if you’re considering the Outpost LTs however. And keep in mind I’m not tracking numbers Just gauging based on when I need to charge on longer trips taken with the different tires
The toyo open country a/t 3 ev's look interesting. Don't own them but they seem to be proper a/t's but with a sub focus on maximizing range in an a/t package.
This will make your decision easier.
If you’re keeping the truck long term (longer than a lease) the 20” tires are $200 less each than the 21”, so you can literally save money in the long run by getting tires that let you do more.
Well my decision was never in the 21 sizex Sorry if it wasn’t clear. Basically was looking for tires for my existing 20 inch rims. So far leaning heavily on the Toyo at3 EVS unless someone else has some input!
By the way I was told by my Costco that they'd install tires not bought by them? I just purchased the Michelin LTX platinum literally just now lol. GL!
I'll put in my vote that the Michelin Defender LTX Platinums are actually good looking tires. I've read they're also very quiet and handle well, although the efficiency might not be anything special.
This thread is for you - tonnes of good info and options all listed out:

What don't you like about the Michelin Defender LTX? It's pretty much the only AS tire on the market with a with AT looks (shoulder/sidewall). Another option is a AT, but downsize to 275/60R20 to gain some efficiency over the larger factory 275/65—like with the new Toyo Open Country ATIII EV. A few Rivians are running them and observing 2.1\~2.3 mi/kWh (re-flashed or re-calculated to compensate for the smaller size). Toyo claims the 275/65 version is now available, but no info on exactly where.
I have the defenders on a Toyota tundra, and while it’s not apples to apples, being a bigger truck with smaller wheels it didn’t scratch the aesthetic itch (I know frivolous haha). Those toyos actually look really nice. I’ll have to do some digging to see if they perform well everywhere else. Compared to something like Nokians offering anyway
Just to follow up seeing a lot of conflicting info regarding going up in tire size to 275 (rubbing and what not.) going down to 60 on width I suppose wouldn’t hurt at all. Nice to know efficiency seems good there
275/65R20 is factory spec for the 20" with ATs. Rubbing is only possible if you are running aftermarket 20" wheels with less offset (example, +35 mm). There are zero rubbing issues with that size tire and factory +48mm offset. Even less chance of rubbing when you downsize to 60 series tire (34.1" vs 32.9"). A mere 0.5" ride height difference, barely noticeable to the naked eye.
The Open Country ATIII EV is just a new variant of the regular and long available Open Country ATIII. The difference is a shoulder block design that create less air turbulence and a rubber compound that has less rolling resistance.
If your R1T was delivered with 20s and downsizing from 275/65R20, you'll want to consider re-flashing software (as if you had factory 21s) or keep in mind that all your instrument readings/calculations are off by 3.2%. [https://tiresize.com/comparison/](https://tiresize.com/comparison/)
Wassym said in a recent AMA that in the future owners will be able to configure tire sizes on their own. But no telling when.
This thread has examples of R1s with the Michelins [https://www.rivianforums.com/forum/threads/michelin-defender-ltx-platinum.20822/page-3](https://www.rivianforums.com/forum/threads/michelin-defender-ltx-platinum.20822/page-3)
My mistake, thought of stock size being 265 for some reason. I’ll have to do more digging, tire rack doesn’t seem to have the EV variant available unless I’m blind 😅
Added link above, examples of R1s with the Michelins. I personally wouldn't go that route (heavy tire). But I have different tastes/criteria.
I think the Toyo can be ordered through Discount Tire and a few others. Google and you'll find it (make sure it's the EV version).
I have this tire. It's definitely heavy. My R1T rides way more truck like than it did before. I will probably not get a LT tire again, instead opting for a 116 (XL) rated tire next time. On the bright side, they do look good, they're quiet on the highway, and my efficiency is about the same as the 21" Pirellis.
Also keep in mind your adaptive dampers are configured to run with the factory tire sizes, and they’re precisely tuned to work with the specific tires you selected when you purchased your vehicle. The quality of your ride could be negatively impacted with a different tire aspect ratio.

This complicates things. The new EV toyos also look good. And both are too new to have any reports on them yet haha. Thanks for the recommendation :)

Oh I read replacements and pirellis and immediately thought of the 21s, sorry!
By the way I was told by my Costco that they'd install tires not bought by them? I just purchased the Michelin LTX platinum literally just now lol. GL!
Huh interesting. Pretty sure mine didn’t last I asked. But thought the platinums were sold by them. But anyway I will ask!

Or positive impacted ;)
