20" Inch Quad MPK Poll: 60 mph and 60°F

[ksurfier]

OK, I just made a run today. The longer distance started at our lower elevation than what I finished at so it was uphill overall. The second one is where I could typically have pretty close to the same elevation at the beginning and the end. There were winds of about 8 mph.

I am also posting a capture from Electrifi for my entire drive today.

I was in AP mode, low, had the cruise control set at 61 but according to my GPS was 60 mph, and I never had to slow down, and sometimes I actually went faster.

Temps started out at 68° and ended at 70. Battery test for 91 when I left dropped to 90 later on. Motte sprayer high 130 lower and 40s in the front, and low 130s high 120s in the world. It started in the 90s though when I got on the highway. I didn’t run any AC or heat. I was using my cruise control with Comma.Ai.

just reminder, this was with the factory computer set to the appropriate Goodyear tires the Territory AT 275/60/20 116H.

Daytripping - Is it possible that you are driving on concrete roadways instead of asphalt and that is contributing to your higher MPK? It would be interesting to know if that’s a factor or not in all of your tests. I’ve seen an increase of 0.3 MPK when driving on concrete.

I am on a variety of surfaces typically. There is a lot of road construction typically on my test routes. Maybe that is a question you can add to the poll.

My overall efficiency has been pretty good even with the topper. It is worthwhile noting that I put on the GY's just before the coldest and snowiest part of our winter. A lot of subfreezing temps. That is the section that is listed as "Territory AT". The next section is when Rivian rolled out the update so you can select the correct tire config and lastly is since I added the topper. It was tracking pretty closely to my non topper usage until I drove about 60 mile in bumper to bumper traffic with the temps at about 100F. That brought my overall efficiency below the non-topper numbers but still better than my Pirellis.

At this point I don't really care any more about efficiency. My range isn't an issue and I love the Goodyears. I knew going in they wouldn't be the most efficient tire I could buy but I wanted more contact patch than the Michelins offered. The tire dynamics have been great. They are very quiet, handle well, great ride quality and tire life seems solid so far. As a bonus, aesthetically, they are one of my favorite tires.

I absolutely wouldn't recommend them for eeking every mile for each electron consumed. For people who are hyper fixated on that, I'd say absolutely buy a different tire. I will say that they are one of the best, if not the best, OEM tires I've ever owned. It was a huge leap for me to move from the Michelin camp to even try these. There are only 2 things that might keep me from buying another set: if I get terrible wear (so far not an issue) or I end up buying Michelin Pilot Sport 5S tires.

Coming back to the road surface, I'll look when I drive through there again. I'd also recommend that as a data collection point if you think it is material. If you don't have it for the other tires, and it is that significant, then your data won't be as relevant.

Here is the Elecrafi screenshot for my tire configurations.
