3.06 miles/kWh - controlled test

[mikehmb]

I had been waiting for specific conditions to run a test on the new tires. Michelin LTX M/S2, 275/60/20. About 1500 miles on them now. Specifically looking for a low wind / low traffic daytime run - this is nontrivial in the Bay Area.

Conditions: about perfect for December. 60 degrees, sunny, no wind (usually a headwind this time of day). Very little traffic at approximately 140pm. Battery temp at departure - 55F. 38ish miles, starting at sea level, ascending to 1000ish feet, and descending back to sea level. Generally flat. Speed kept at traffic, between 60-70 most of the way (except the climb/descent, which is generally 40-ish mph).

Conserve mode on the flat (25 miles), switched immediately to AP for the climb/descent and remaining distance.

3.06mi/kWh unadjusted. Reduce by 3% for smaller diameter tires. Same test a few months back and was seeing around 2.5 on the ATs.

TL;DR - unsurprising results with all-seasons vs. the stock Pirelli ATs.

(Yes, this was about as close to ideal conditions as possible, and no, I am not a hypermiler - usually I don't much care, but I needed to know if the new tires would get me a significant boost in distance for a couple of trips planned where I need to venture pretty far from reliable chargers.)

Please ignore the filth on my center display. Truck needs a bath.

Did you eat Five Guys before taking those pics?

I still have brand new tires and will be doing a similar test around 1500 miles in as well. Thus far my city miles have been insane but I haven't had a chance to go on highway yet.

I don't know what unspeakable thing transpired prior to someone touching that screen, but I'm going to ask my family to do an isopropyl scrub of their fingers before they're allowed back in there.

I have found that the AO screen protectors are actually pretty good at (at least delaying, if not minimizing) really mitigating fingerprints. FWIW: https://abstractocean.com/products/ultra-premium-tempered-glass-screen-protectors-rivian-r1t-r1s (I'm not affiliated with, nor receive commission for recommending these). In certain cases, they seem to minimize glare as well.

That is awesome efficiency. My lifetime with general grabbers HTS60 is about 2.35 with about 13K miles on it now. How is this tire in raining wet condition? Im debating between this and the rivian goodyear tires for my next set.

I'm about to find out! Heading to the office shortly.

That said, I had the previous iteration of these on my MDX 10 years ago, and they were superb in the wet.

I bought the same tires (but 275/65/R20) and have 2.5 mi/kwh for the last 30,000. They're much better than the Pirelli's, which I had to replace twice after 15K.
