20" Inch New update mileage for 20"

[LL75]

Are you on the 20 inch wheel now with the grabbers? Can you please list the spec for the grabber? And finally, does it equal the overall wheel+tire circumference of factory AT wheels plus pirelli AT tires?

I have the factory 20 AT wheels with original pirelli AT. In the Winter I run the Blizzak LT that have the same circumference. But I am just about at 30,000 miles and the ATs (with only half that mileage) are way louder than the Blizzak. So when I come off my winter tires shortly, I may just swap in new grabbers or something like that.

I offroad a bit but it is all soft sand where my LE Quad gets me no problemo (airing down really is the most important thing in soft sand).

The size is 275/60/20. Not like the original eom of 275/65/20 .
xl load range and 116 load rating. This is all season tires and I don't do any of off road or soft sand stuff. So I can't comment about that

Thank you! Will the new update let us toggle into this option (275/60/20)? If not, and I get these, my speedometer will be off a bit (though it looks like it would be like 1 mph).

It does. But it default to the good year wrangler. Your efficiency will be like the 21" OEM

Does everyone that do a switch to 275/60/20 sizes with the Quad get 285 ish all purpose miles with 100% charged?

This is what I am seeing with mine post switch (quad with brand new Toyo 275/60R20 set up on new 25lb wheels). Doing a speedo test I am also seeing approximately a 2mph difference in speed (if R1S speedometer says 65, it’s actually 63 using two GPS speedometer measuring devices).

I am thinking of setting up a 21” wheel set up to see if it addresses my comment above, but also shows an increase in range.

In conserve it indicates 327, AP is 294. This is with the Goodyear setting (but I have Yokohama Geolandar CV 4S). My long term efficiency indicates approx. 293 miles in AP, but I think that could be high by around 10 miles or so. TezLab shows 305 miles with full charge ‘based on your driving style’…
At 70 MPH (43 F) I get around 2.15 MPK in AP, or 2.25 MPK in Conserve…I only use conserve on long trips since it can only increase range by around 10 miles if driving ~200 miles. So at 70 MPH I’d only get around 280 miles on a full charge in AP and maybe 290-295 in conserve.

That is weird. Mine is 285 with Good year in AP and low 300s in conserve. I don't think the Rivian would know which brand of tires 275/60/20 we have on. Everything is default to the Goodyear.
Teslafi also showed 285 for 100% charged.

Maybe degradation, how many miles do you have? What’s your lifetime average MPK? Multiply it by 131 and that should be your range…

FYI when you change your tire size, and it says vehicle reset is necessary for accurate range, what it's really saying is "click okay to reset your vehicle right now."

Good thing my boss has a Rivian and will understand why I'm late.

Many of us switch from 21" to 20" size of 275/60/20 all seasons tires and have achieved same or better efficiency as 21". With the new update came out , the prediction of 100% charged went down from 305 all purpose to 285 miles. I know for sure this is not true with my general grabber hts60 since my efficiency was about 5% better with 18k miles on it than my 21" OEM.
Is it just a general prediction Rivian based on with their good year tires ?

Did you choose the Rivian "all season" 275/60R20 option? I chose that size but aftermarket all terrain and it shows this:

My lifetime before the goodyear is 2.31 which put it at 303. 95% all-purpose. 35k miles

I choose 275/60/20 all seasons which is the good year that I currently have .

When you changed it, did it reset the vehicle?

I did this 3 days ago and it reset the vehicle. Took like 5 minutes to reboot. Someone on facebook group changed his 265/65/20 OEM Pirelli to 275/60/20 in the system and it changed to 298 miles all purpose !! So, there is something is odd about my car.
