No regen after tire replacement

[jordanthompson]

I just replaced my rear tires (for the umpteenth time) and had a new experience: I replaced the Michelins (a little larger diameter than stock) with the stock AD08's. As I left the tire shop, I lost all regen and had a warning on the dash. It went away shortly after and regen started working again. When I had a chance, I found a stretch of road and retrained the car for the new tires and everything seems to be fine.
It was just a major shock to coast when expecting to brake in heavy traffic.

I know, still don't get use to it after a range mode charge and the initial driving off / braking.

Did you use the Learn Tire function? That should resolve it.

I did (this isn't my first rodeo) but this happened as I was pulling out of the tire shop (didn't have enough time or distance to even think about the learning function.) I only lost regen for 5-10 seconds, but I'd never experienced it after a tire replacement before. As was mentioned earlier, it's always a freaky feeling after a range charge, but I've learned to expect that and plan for it. Pulling into a Florida suicide lane is nerve wracking enough (especially with all of the snow birds down for the winter) I wasn't expecting to need to apply as much brake as I had to.

Yeah watch out, a lot of those snow birds are from Montreal. They drive like the car is expendable...

I know this is on Roadster forum, but i think i'm having this same issue with my Model 3.
I just replaced the original Michelin with a new tires from Tirerack Vredestein Quatrac 5 and now my regen has been significantly weaker, especially from high speed >40mph

Do we have a learn tire function on Model 3?

There’s a million threads on losing regen with winter tires. Lots of reading on there for you. Yes you do have that function and it’s only marginally better than what you have now.
Who has lost regen with winter tires?
That’s just the Canadian site, I’m sure there are more.
