Avon AS7 Gen 2 vs Michelin CrossClimate 2 — Compared

“We downsized from 21” stock on GTline to 20” rims and put on the CC2s—can’t stand the ugly stock rims and plastic covers. It got so much quieter that we noticed we could turn the radio down from 6 to 4 on the secondary roads, and down from 8 to 5 on the highway. Efficiency improved slightly, possibly due to lighter weight wheels.”

“Michelin CrossClimate2 efficiency surprisingly good! Just put in a new set of Michelin CrossClimate2s to go along with a move from LA to New England. I was a bit worried about the mileage/range hit but figured the safety in the winter outweighed it. I'm pleasantly surprised! On an all-highway trip from Boston to New Jersey, gas MPG was a steady 42 mpgs and I got about 45 miles on the battery, although I drive like a grandma at the posted speed limits so I think I was close to 44 mpg/45 EV miles on the old OEM tires. Around town in suburbia in good weather I'm still running between 4.0-5.0 miles/kWh. I estimate, at worst, a 5% drop in efficiency. Pretty good considering the Michelins feel so much stickier!”

“New CrossClimate 2 tires almost stranded my family. Massive efficiency drop on Model Y. Just a heads-up for anyone swapping to Michelin CrossClimate 2s. Put a set on my Model Y about 3 weeks ago from Discount Tire and just did a road trip from Denver to Taos, NM with my wife and two toddlers. We charged up to 90% at the Pueblo Supercharger, and the Tesla app estimated we would arrive in Taos with 15% battery remaining. Well, the new tire efficiency hit is incredibly real. The range dropped so fast that we were tracking to hit 0% and had to make an emergency Type 2 charging stop on the way just to make sure we didn't get stranded with the kids in the car. I’m now seriously thinking about taking advantage of Discount Tire's return policy and going back to the OEM Continental ProContact RX. Has anyone else faced similar problems or massive efficiency drops when switching to the CC2s? Does the range eventually get better after a break-in period, or should I just cut my losses and swap back to the Continentals? I need something reliable for road trips with the family, so I'd love to hear your suggestions and experiences!”
