Tesla Model 3 RWD Loses Regen With Winter Tires?
The change to winter tires surprisingly affects regenerative braking, it seems.
Tesla Model 3 owners report that after they switch to winter tires, the regenerative braking power significantly decreased (by at least a half of the normal force). The case seems to concern rear-wheel-drive versions only.
We would expect regenerative braking to adjust the situation and decrease if the traction cannot handle snow or ice, but a decrease of regen right after the change of tires is kind of surprising, especially at temperatures of 6°C (40F) on a dry road and with a heated-up battery (no charging power limit).
“Something strange is happening to Tesla Model 3 RWD vehicles. After installing winter tires, regenerative braking is about 50% weaker than on the all-season tires?!? Leave a comment if you are (or are not) impacted by this issue. 80Km/ph = ~50Miles/ph. Please subscribe if you enjoy my videos! #Tesla #Model3 #TeslaCanuck”
According to the video on Tesla Canuck channel, the issue is known to Tesla, so maybe there will be some remedy or at least we will know the reason, depending on whether it’s a bug or a feature.

“Yup, me too. I put on my Blizzak’s and immediate decrease of regen. I would say way more than 50%. The regen is a bit stronger in the slower speeds for me. Sometimes below 30kms/hr, sometimes below 20kms/hr. I submitted a ticket to Tesla and they responded that they are aware of the issue and working on it. Until then, I couldn’t take the clunky driving of the regen kicking in intermittently, so I switched back to low regen. I have never used my brakes so much in the last week or so since I got the M3 in early June. Hope they fix it fast. I miss one pedal driving.”
