All Terrain Tires Barely Slow The Rivian R1T Max Pack - 10% Challenge Road Trip Simulation



TLDW: 2025 R1T Tri-Max on AT's is very close to both 2024 R1T Dual-Large and 2024 R1T Dual-Max.

2025 R1T Tri-Max 20" AT: 84-miles
2024 R1T Dual-Large 21": 85-miles
2024 R1T Dual-Max 21": 85-miles
2024 Silverado EV LT Extended Range 22": 90-miles

Let the internet jiu jitsu begin!

Interesting...why didn't OOS include the results from the 2025 DM 22" range wheels from earlier?



Added the results below:

2025 R1T Tri-Max 20" AT: 84-miles
2025 R1T Dual-Max 22" AS: 75-miles
2024 R1T Dual-Large 21": 85-miles
2024 R1T Dual-Max 21": 85-miles
2024 Silverado EV LT Extended Range 22": 90-miles

It's very odd how the Tri is so much better, even on AT wheels. I suspect on 22s, the Tri would have hit 90mi in this test.

Very good question to be sure. I guess you would need to comment on the video or message OOS.

I am impressed that the 2025 R1T Tri-Max on 20" All Terrains did just about as well as the 2024 Dual-Large and Dual-Max on 21" Range Wheels, however, I still just do not see the value unless you really want/need the latest and greatest with "better" interior options and ADAS, etc.

I want Rivian to do very well and not just because I am a shareholder. I want them to make a great marginal (net) profit per unit, however, I just do not see it as a consumer.

A used Silverado EV 3WT (similar to the LT Extended Range) can be had below $60k or new below the R1T price point. Granted one gets a much nicer truck with the R1T. Just seems a bit weak on the effective range (10% Challenge), max tested range at 70-mph, and charging curve.

I know, I am putting too much faith in OOS. I don't really even like OOS, but they are one of the few outlets tabulating all of these results in a fairly consistent manner with relatively logical and uniform testing procedures.

State of Charge is another great outlet, though Tom seems to get less test vehicles and focuses more on charging and 70-mph range testing (following extremely similar testing procedures to OOS).

Rivian's R1T improvements on paper appear huge, in the limited real world testing we can see very minor fractional improvements. Yes, I understand these Gen 2 are new products and I should not try to compare an old Large Pack with a new Large Pack, etc. My point is, we should see much larger improvements from the heat pump, 17 ECU's dropped to 7 ECU's, new calibrations.

The sense I get is the stuff (Gen 2) is essentially still in Beta for big things like efficiency, charging, range, sound system, ADAS, etc.

I really want Rivian to kill it going forward. Rivian really needs to show us dynamism with Gen 3 and new models (R2, R3, R3X).

I have my flame suit on now, so do your worst and light me up .

There is variation in charging performance, battery temperature, ambient temperature and wind and traffic conditions that a one-off test like this just does not capture very well. Don't put too much faith in these numbers, they are only single sample estimate.

IMO, it depends on your needs & financial situation. Like I have said many times my Tri Max is third R1T. First two were both early gen 1 QM (one was a dem). I drive 35,000 miles annually and the TM is definitely "worth it" to me. The increased efficiency (especially in cold weather), better build quality, lack of wind noise, better seat, better tonneau, better cameras, and, potentially, better upgrades coming make it a good purchase for me. If I didn't get paid 65 cents a mile on 24,000 of those annual miles I might look at it differently though. This vehicle isn't cheap, but I get my electricity for 11.2 cents "all in" cost including taxes, etc. That rate is locked in for 18 more months. In warmer weather I was getting 2.75 mi/khw. That means I'm driving for 4.1 cnts a mile (rarely dcfc). If I have 50 cents a mile depreciation it still works. Everybody's situation is different, but for EVs in general the more miles you drive the better deal they are. If I didn't drive 20,000 miles annually I wouldn't own one.

Couldn’t make any sense of what is trying to be described by this test, didn’t really want to watch the video but curiosity got the best of me.

For clarity:
-Not sure which tires are being used here
-Test consists of discharging battery to 10%, then charging 15 minutes (49 kWh, in this case).
-then discharging (driving) that amount to determine how many miles can be driven from 15-minutes of charging…

this could easily be conveyed as:
“28% range test at 81 mph” or
“15 minutes of charging range test at 81 mph”

my main takeaway is that it takes (costs) 124% of the battery pack to charge to 100%…in this case $4 energy inefficiency…curious how Rivian computer adjusts for delivery inefficiency…

Also, looks like they could expect a range of 300 miles for the 141 kWh, which is 2.13 MPK at 81 mph….seems really good!

The '25 DM didn't seem to be a particularly good specimen. The tri- in conserve will perform the same or worse than the DM all things being equal.

Excellent point, please recommend other samples tested in a consistent manner that we can refer to. Just using what is available to me.

This does not answer your particular question but it is a data set I put together recently that might offer some insight and intuition for your questions.

Many thanks!

The sheer weight of the truck and battery are physics one cannot avoid. Without significantly different technology, efficiency and battery size are the two ways to increase range. Dropping 1000lbs off the R1 would be significant.

Battery temp?

For me the take away is that all the rivians are about the same in charging. 400v and similar cell C rate means you get about the same kwh in 15 minutes. So unless you have a better charge curve like maybe a gm 900v bigger pack, you can't stuff more in.

All rivians have about the same wind resistance which is the largest factor in consumption especially at 80mph. Secondary improvements help in some circumstances.

Road tripping in the manner shown in the video means you can pick any Rivian and get there in the same time as any other Rivian.

100%.

Except if you put the Wakeshield bed topper on the T, it could add 5-10% to highway range. Nobody has posted independent tests to confirm that, but the theory is sound and I believe it is accurate.
