Hello all,

This is not a usual report - just a quick summary of the road trip I just did from Austin, TX to Frisco, CO, and back through Durango, Taos, Santa Fe, McDonald Observatory, and back home.

R1T 23, Quad, Originally 21" wheels replaced with 20" Goodyear RIV tires on MSW type 52 wheels.

The Good:
1. "Do not buy an EV if you can not charge at Tesla superchargers" - very wise message.
Except for a few charging sessions, I charged at Tesla SC and it was flawless. Just worked. Standard charge curve (that is mediocre but it is what it is).
Also, all SC that I charged at were located near restaurants (some better, some worse). Or supermarkets. Huge plus vs EA. The average charging time was 35-40 minutes. Never waited for the charger! And they all worked!

2. Goodyear RIV 20" Tire worked great for me - I got 2.22 miles per kWh: (truck with 2 people and fully loaded bed).
Driving 10% above the stated speed. (all temperatures are in Celcius)
Rivian R1T R1S 3,000 mile road trip from Austin, TX to Frisco, CO - Good/Bad/Ugly 1724698730254-xo
Rivian R1T R1S 3,000 mile road trip from Austin, TX to Frisco, CO - Good/Bad/Ugly 1724698756623-cx


3. The truck had no issues at all - I was able to charge every time w/o thermal issues, preconditioning worked well, all was great and worked well. The A2Z adapter worked perfectly well. The only thing - you need to make sure the truck will not take over the charging session with a higher price. Happen to me twice as I moved the lock switch on the A2Z adapter by mistake and in this case Tesla lost the session and Rivian took over.

4. Price - only once I was able to charge for free at my friend's house - 100kwh free. The other 1277 Kwh was paid in $. The overall price was: $480. So the average price per kW - 0.38c. Compared to a 20mpg car - 3k miles = 150 gallons *$3 = $450. So basically the same price as gas, which is awesome, and huge thanks to Tesla SC (and Elon / RJ that got this agreement) for this price. EA would be much more expensive. The most expensive one was Government sponsored Francis charger in NM - 0.59c. Great example - government is never a solution, it is a problem.

The Bad:

1. Noise. Wind and tire noise on Texas roads - there are silent roads and there are very noisy ones. It seems that some Texas road's surface is "grainy" and tire noise is just horrible. The problem almost does not exist in Colorado and New Mexico. However, wind noise is horrible when driving 75+. Very bad at 85mph+.
And I have sealers all across - doors, windows, etc. I used all techniques published on this forum.

2. Driver+ - this is a true embarrassment for Rivian, and RJ should be personally ashamed. Driver+ uses the same Mobileye that the BMW X5 2021+. And it is many times worse than BMW. It is a shame it was released like this. Side cameras have nothing to do with this, the main windshield camera is what is important for Driver+. It will disengage suddenly and reappear again. Most of the roads were not covered by Driver+. When you pass a huge semi you need to adjust the position in line a bit and Driver+ will disengage. And the last one - in Texas, we have roads with 85 mph. So we drive 90mph. Driver+ max 85 mph ...

3. Steering - road imperfection passes to the steering wheel. At 85mph wheel will shake most of the time because of this. And it is not an alignment or balance - when the road is super flat there is no shaking. It is a road imperfection that passes to the steering wheel. This does not happen in BMW or other premium cars.

4. Windshield quality - the windshield of Rivian is soft. It is not the angle or anything else - it is the glass. The good - I did not get any cracks. I had 3 direct hits of small stones and got many pits but not a crack. Again, compared to the BMW X5, after 40K miles I have fewer pits than in Rivian after 20K. By far. The glass specs Rivian uses are too soft.


The Ugly:
Nothing really. The truck was reliable and worked well. Got us to Leadville 100 miles run, served us well there, and on our way back. I was fine with the stops that added 25% charging time. But this personal, my wife did not like it :) Tesla SC is the game changer. For the good.

Nice report, thanks for sharing! You might get even better efficiency if the tires are inflated to 48psi when cold (recommended inflation for the Goodyear tire).

Thanks for the write-up. I've been thinking about replacing those noisy ATs at some point and the goodyears may be a good option. Nice to see real world mileage on that tire.

I saw it somewhere - do you have a link for this? As I tried to find what PSI these tires are recommended for Rivian and did not find any formal info

Shap-great write up. Very different than others so it was refreshing. I'm waiting for my Rivian adapter to take a longer trip but I have taken one 800 mile round trip.

On your "bad" section point #1 and #3. I wonder if it was the tyres? I've driven in Texas at an average speed of about 80mph on most highways. Speed limit was 75 where most drive 85. This is in a R1S with 20AT and everything was smooth. Road noise or steering feedback was good. I did get a fair amount of wind noise as I have not done any of the improvements on the forum. Cheers.

Thank you.

Depends where in Texas you drove -" the road surface of paved Texas highways is pebbly and these pebbles cause the tires to make a LOT OF NOISE so the highway is LOUD. Even in very isolated car like BMW.

When entering Texas from Oklahoma, New Mexico and Louisiana you always know when you get to Texas...even if you are sleeping!"

Quoted from one other guy that explained the problem better than me ;)

Generally, these tires are a bit more noisy than 21" OEM. City pavement is quite but when you get to rural roads and highways - volume goes up to 11...


As for steering feedback - same issue, driving fast in NM or CO had very little shaking. On Texas roads - much more. But different from road noise , that even BMW will pass to the cabin, steering wheel in BMW will not shake even a mm. I guess it is a design flaw, and more heavy steering column may help.

Great report. I've been itching to try the trip from Austin to Park City, Utah, so this is a great primer!

The recommended inflation pressure is on the drivers door jamb sticker. I corrected my earlier post to read 48 psi when the tires are cold. Once they warm up, the inflation gets a little higher. I believe Rivian recommends 48 psi cold tire inflation pressure for all the different wheel and tire sizes.

Oh, that what I had, 48 psi cold in Texas when I left. Btw, that become 44 psi cold in CO ;)

I think I lost about 1.5 PSI over the entire trip.

What I was really surprised is how perfect charging with SC worked - I had a bad experience on my previous road trips with EA and EVGo. Tesla SC is just another level of comfort.

I totally agree with your assessment from your trip. I took my R1T from SoCal to Vancouver and it worked flawlessly but the driver+ was a big disappointment. Whenever it goes through curved freeway it slows down making the driver behind me getting mad for breaking for no reason.

Thanks for the information.
If you want to go on road trips, get a Tesla is still largely the rule to follow becaue of the glorious Tesla supercharger network. There are still areas, though, especially in my neck of the woods, where I just could not complete some trips relying on Tesla SCs only, unfortunately. In fact, ChargePoint made it possible for me to plan and complete my trip last weekend. But it is getting better.

Glad to know A2Z worked well for you!
My A2Z Typhoon PRO will arrive this week. Have a very long trip around WA and OR coming up, will use mostly RAN, plenty around in the PNW; will use only two Tesla SCs at most.

Perhaps your 20 in. tires are noisier, ATs?
Most importantly, Texas is hopelessly addicted to chip seal paving. It is awful. I know it firsthand.
Have 21s on my R1S, noise is fairly low, but I cruise along leisurely 70 mph at most.

Can you explain this charging price thing with the truck taking over?
I own Teslas and always select "Charge another EV" in the Tesla app to charge my R1S. I noticed that there is a ~30% average markup on electricity cost for my R1S at Tesla SCs compared to what it cost to charge my Teslas.

I will not use Driver+ because it is woefully inadequate. My last time using it, vehicle would not stay centered in lane, veering back and forth within it. Surprised I was not pulled over for DUI. I find adaptive cruise control great.

The windshield quality. So is the windshield on Teslas soft. Replaced one already that cracked. Pay me now or pay me later, the way I see it. Reason why I opted to add full glass coverage including headlights for my EVs with no deductible. Paid for itself already.

As one of the designer's of the Goodyear Rivian tire, I can confirm that noise performance was a priority for the tire design. Certain road surfaces can introduce new harmonics for different types of tires. On my R1T with the Goodyear tire, I definitely notice wind noise at highway speeds, but I have been happy with the noise performance on the roads I have driven.

Wind noise can be fix with a little black silicone putty. They are gaps on the belt line and on the upper windshield corners.

4. Price - only once I was able to charge for free at my friend's house - 100kwh free. The other 1277 Kwh was paid in $. The overall price was: $480. So the average price per kW - 0.38c. Compared to a 20mpg car - 3k miles = 150 gallons *$3 = $450. So basically the same price as gas, which is awesome, and huge thanks to Tesla SC (and Elon / RJ that got this agreement) for this price. EA would be much more expensive. The most expensive one was Government sponsored Francis charger in NM - 0.59c. Great example - government is never a solution, it is a problem.
I think the assumptions on gas price and mpg are a little off here.

Average gas prices last week according to AAA:
  • Texas - $3.027
  • New Mexico - $3.229
  • Colorado - $3.408
  • Average Price - $3.221
Also, for MPG, I think the 20 mpg comparison is not super fair, mostly because the Honda Ridgeline is one of the only trucks that hits that number on highway trips. From personal experience, a Toyota Tacoma would be at 17 mpg on a 75 mph highway stretch.

Even still, with your assumption of 20 mpg and using the more accurate gas metric, it's pretty much dead even at $483.

If you did use 17 mpg for a Tacoma it would be $568.

And with a Ford Raptor getting 14 mpg (best performance equivalent to an R1T) it would be $690.

Great report. Only want to add one thing. Wife will complaint about any L3 charging bcz of the wait. They don't complaint about driving in the city and charge at home. You should have seen my wife when I was struggle to lock the a2z adapter to charge. Eyes rolling everywhere
