20" Inch YOKOHAMA GEOLANDAR CV 4S | 275/60R20 - 116H - 660AA - 3PMSF

I don’t, but LL75 does, he has been saying the are same or slightly better than 21” OEM, so maybe 2.4 MPK or so?

Each vehicle and driver are different, so individual deltas are more important to track efficiency changes.

Someone should give these a go, $500 for a set of 4!

Now that we have plenty of 116 options, I'm back in the 116 group to increase safety margins. Despite 115 technically working!

Agree, seems like Rivian has drawn a line in the sand since all options are now 116H or better (and XL or HL)...it's just funny that you could purchase four of those for the price of one OEM tire...
My takeaway is that the special "EV" tires are just a way to squeeze an extra $200 per tire out of consumers...
This cheapo $130 tire even comes with a 65k mileage warranty...go figure

Updated with a 176 mile one way trip today (Conserve w/ AC running), tires are ~2.2 MPK.

Well that's kind of disappointing... it's not far off from OEM tires, or my AT3W, if running in conserve. In fact it's only 4% better than my AT3W in AP with an RTT. I was expecting better in an All Weather tire with more focus on road than off.

I'm going to put my All Season Ram wheels back on and see if I notice a handling difference. If not, I may stay in the 2-sets club. The AT3Ws drove ROUGH after my last off-road trip, might've lost a weight and just need rebalanced though. Or they're just ATs and naturally rougher ??‍

I think it's slightly better than the OEM Pirellis, a 900 mile trip in April with OEM tires ended up being ~1.97 MPK. It was cooler weather so no AC but increased air density likely meant a little less efficiency. Ultimately, these tires ride so much better than the OEM Pirellis, they get same or better efficiency, and they cost significantly less. Seems like an easy choice if you need 3PMSF tires. I'd be curious how the Grabber HTS60 and Defender M/S2 compare to these...

They'll definitely exceed it in MPK, but no 3PMSF, necessary for winter driving through many passes. I hate that 3PMSF uses acceleration and not stopping, the much more important safety factor, because a lot of non-qualifying tires have proven better stopping and handling numbers.

My last two trips from Dallas to Norman (roughtly 190 miles) with the Grabber HTS 60 was 2.31 conserve mode compared to my OEM 21" at 2.29 conserve. Average speed was 69 mph with majority of the times in 80 mph or more. The 69 mph aveage due to slight traffic on I-35.

Tempting. ? But, not available in stock 20” size of 275/65r20. Don’t really want to deal with the calibration change from 34” to 33”.

I assume you started with 21” then made the switch to 20”, thus the 60 profile.

Hey, coming over from Reddit where I did some tire/wheel writeup that ended up with the conclusion of using this size of Yokos on 20in AT rims. The trick to calibration here is you just tell the computer you're using 22s (275/50R22). Then you're only +0.6% larger in OD than calibrated, so the odo/speedo is basically perfect. Only slightly off but you get similar variations with warm/cold day tire pressure anyway.

Hope that helps with calibration.

Are you saying you found a way to change the computer to the 22 inch OEM size without having to take it to Rivian to do it? We have heard this will be possible in a future update.

From their (detailed) Reddit comment they don’t realize that we can’t just change a wheel setting like on a Tesla, but hopefully that will change soon…

No, you would still have to have Rivian do it until that software update comes. However if they do it for you (or you do it later) you can run a smaller OD tire on an A/T 20 wheel, which should mean more sidewall than a 22 and more range than a 20. Bit of a happy medium option.

After 4,350 miles tire wear is minimal (10/32” fronts and 11/32” rears). Tested at 80 mph, conserve was about the same as AP (1.78 vs 1.75).

Type A durometer - 62-65 for this tire compared to ~70 for OEM 20” Pirelli ATs.

What tread depth did they start at?

And can you give a 66mph All Purpose/Standard 10-20 mile round trip test result?
