20" Inch Best 20" Tire for Max Efficiency (R1S): On-Road with Occasional Snow Driving

[rogersmj]

Can't speak to snow performance of these tires, following thread.

Well I recently had the change to thoroughly test the Rivian Wranglers in some pretty serious fresh snow, and they worked great. No issues whatsoever getting through 15"+ plowed segments/drifts. If you're doing mostly on-road, with the occasional light trail and/or blasting through some snow to get across town in a winter storm, I think they're a great option.

I’ve been looking at the Hankook ION HT as a replacement to the AT tires. Haven’t seen reviews yet, especially for a 20 wheel and not 22. It’s not 3 peak but looks to hit every other need for someone not doing heavy trails.

There are threads with data from those already running it. Efficiency appears to worse than the factory tires they replaced.

Thanks for the response. Appreciate it.

Speaking about the Michelins, this is a good thread on Reddit that still is informative but does contain comments about no boost in efficiency. I took that to mean no efficiency boost when going from stock Pirelli 21s to Michelin 21s. There is the "speculation" comment that going from stock Pirelli 20s to Michelin 20s will see a big boost in efficiency but I have yet to find that specific data.



And I get that the comparison is fundamentally dependent on the base tire in the comparison but trying to extrapolate from a comment about "21s" to a conclusion about "20s" is problematic. Thus my original post.

Stock Pirelli in 20” are 34.1” ATs. It’s a given to observe big gains from switching to smoother rolling AS of equal diameter or less. ATs are inherently less efficient because of tread design (larger voids, greater rolling resistance). Even for fossil fuel cars. The same tread design that gives them better traction off-pavement are the very same reasons they are less efficient on-pavement. It’s a trade off.

Speaking of trade off… The OE Goodyear Territory AT RIV is a AS/AT hybrid.

Hi all, I’m an engineer at Goodyear that helped develop the Goodyear Wrangler Territory AT for Rivian. This tire performs well in a wide variety of conditions, including snow (3PMSF rated). Efficiency was a top design priority. Updating the software from the OE 34” AT to the Goodyear 33” tire improved range from 369 to 385 miles on my R1T. @DayTripping and others have documented impressive efficiency numbers with the Goodyear tire in this thread… https://www.rivianforums.com/forum/...-20-factory-at-tires-saving.37522/post-753458

How is the road noise of the Territory AT compared with the stock Scorpion? At 13k miles my Scorpions seem to be getting annoyingly loud.

Far quieter. The Scorpions are designed as off-road AT. Not the noisiest of ATs. But expectedly louder than tires that aren’t true ATs. Again, the very same traits that give ATs better traction off-pavement, are the same traits that make them less quiet and less efficient than tires that are more pavement-oriented.

But important to note, the Scorpions have UTQG of 640, while the Territory ATs are 580. These are self-reported stats from each manufacturer. And some users reported they need new tires at or around 20k miles. The bright side of that is they are less than $300 each. Service life of the factory Pirelli ATs are generally in the 30-40k range, but in the mid $400 range per tire.

ABSURDLY more quite on the Goodyears.

I have the Goodyears on my truck. It's in service, and the Rochester SC gave me a loaner with Pirelli AT's. Literally drove them back to back in a lake effect snow event. I would give the edge to the to the Pirellis in total traction. The Goodyears are still quite good, but tend to slide a bit more, and don't have quite the same "sure footed" feeling as the Pirellis. Both went through 18"+ of snow without issue or complaint at any level.

Anecdotally I was in another Rivian yesterday in Louisville that had the 21in All Season tires on it. We drove through an untouched parking lot with about 8-9in of snow/ice on it and didn't have any problems there either. The Rivian traction/motor control can make up for a LOT of tire shortcomings!!

I have no data to provide but my experience with buying tires is that the data only got me close, final decision seems to always end up being a combination of recommendations from people who’s experience I respect, my own experience with various manufacturers, and a final “gut-based” decision. The only times I have been able to calculate my way to a final tire decision and avoid having to make up my mind have been with snow tires, racing slicks, and odd sizes.

FWIW Nokian tires seem to me to work better in snow than similar tires from other manufacturers.

I swapped form the AT 20 Pirelli to the GY 20 OEM ATs and at the time I was getting just under 2.0 miles/kWh on Pirelli's. Since I switched in July I've put about 7500 miles on the Gas and I'm getting about 2.15 and that includes an LA trip, several up to South LakeTahoe, and daily driving. The efficiency has dropped this winter by about .04 which is expected and my efficiency is likely a little less as I use Pet mode quite a bit as my bestie always goes with.

On a Gen1 Quad with the new tires, if I charge to 90-95% I can make it home to Palo Alto on one charge. Going up always requires a stop in Placerville and it'll take 30-35% of the battery to get up and over the pass from that point. I can't comment on how well they respond in snow as I just haven't been up to Tahoe when there was any on the roads (thanks to this dry winter).

Overall I've been happy with these tires and they are way less loud than the Pirelli's ever were! At this point I'd buy them again as they are a great all round tire.

what you mean by " Updating the software from the OE 34” AT to the Goodyear 33”" ?are you talking about switching the tires type in the tire change menu?

Exactly that. Tire Swap feature in Vehicle Settings. We gained that in 2025.06 OTA.

Thanks for the info! My setup is very similar: Gen1 Quad, El Cap exterior and OC interior, 20" stock Pirelli ATs, etc. but it's an R1S. And I get ~2.00 mi/kWh. We also got to Tahoe (but North shore so we go I-80) and L.A. as well. We are in Sunnyvale. So quite a similar use case to you just an R1S instead of an R1T.

Based on your experience and the comments from others in this thread, I am now leaning towards the Goodyear Wrangler Territory AT (OEM).

I wasn't looking to go from 2.00 mi/kWh to 2.7 or something huge like that. I just wanted to find something that would give me some non-negligible efficiency boost but still be good in snow when we go to Tahoe. What I didn't want to do was to end up getting something that was "OK" on snow (but still possibly worse than the stock Pirellis) and was also just a negligible increase in efficiency (e.g. 2.00 -> 2.03).

Yes, the Goodyear Rivian tire can be selected in the software settings. This will update the speedometer to reflect the OD difference as well as the range estimates.

Will likely be looking for tires later this year. Leaning towards the 33 instead of 34 overall so that I can put on cables for snow just in case (34 can only use snow socks from what I understand). I do like the AT tires overall even if they are a bit noiser, but overall the Michelins will likely be better for everyday use. Will be keeping an eye on this thread.
