Michelin Cross Climate 2

[MichaelC]

I now have 1 month of drive time on the Cross Climate 2 tires I got with my aftermarket 19" wheels (see Aftermarket wheels? thread for details).
Overall, I am very happy with their traction (better than the stock Continentals) and comfort/noise (equivalent to the stock Continentals). I have seen an efficiency hit of 0.4 mi/kWh on average, as shown in the summaries below:

September was all on the stock 19" wheels with Continental tires, and October was all on the aftermarket 19" wheels with Michelin tires.

My longest road trip to-date was in September (776 miles round trip), whereas my longest trip in October was only 97 miles. Temperatures have also cooled down a lot recently, which has had an impact--but I don't think enough to really skew these results.

I will take much longer road trip in mid-November (Kansas City to Baltimore and back), which will give me significantly more experience with these tires.

Interesting. I am currently getting 2.7mi/kWh on my winter tires and 19" kaliedo spoke wheels. Temperatures are already below 32F overnight.

We got our first freeze last night/this morning but have at least one more roller-coaster week of warmer temperatures ahead. Your previous reports on cold weather efficiency losses has me expecting lower numbers once the local temperatures stay consistently cold.

I plan to post monthly updates here so all seasons are represented. Granted, the more open wheel design will reduce efficiency a bit at higher speeds, so results may vary for those who use them on their stock wheels.

I'll be curious to see how well the built-in navigation deals with temperature changes on my upcoming road trip (which will also include some big elevation changes).

While not totally scientific, I have seen some efficiency differences between a garaged EV and cold soaked one. There's probably an operating temperature range for the battery and motors as well as the heat pump vs resistive heating temperatures. Crossover point is somewhere around 14F.
