Who has lost regen with winter tires?
- Thread starter Darthbenji
- Start date
I have v2018.50 on my car, which has fixed the regen issue for me. Tesla seems to have stopped rolling that version. But, hopefully the next version that gets pushed will fix this for you. Hang in there!
I had same issue with the Sottozeros. The SC comment about non approved is not valid. Valid as in it is the policy, but not valid in the occurrence that RWD cars are having even with Tesla approved tires. I had posted the email from executive review that they are aware of it. My local SC was not aware of the issue as an FYI.
Returning tires? Can that be done after mounting?
Seems to be sporadic - my Sottos from the Tesla package are fine. Though if it's not the car "learning" about the new tires (which I thought was a possibility since my regen was gone then suddenly came back shortly after), then it must be the newer firmware that was sent out after I got the Tesla package installed?
I don't know. They were bought and mounted by Les Schwab less than 12 hours ago. My husband said he'd try and return them for me if that would fix the problem. Sounds like it's not the tire and it would just be wasted effort to swap them out.
After 2018.50 I'm almost totally back to normal. It behaves slightly differently, but it's basically as good as it was. RWD with Hakka R3's.
Agreed here as well. Michelin X-Ice tires which are very soft and best described as "squishy" tires. Version 2018.50 is great on my car for regenerative braking performance, even when its warmer.
Back a few pages that was stated as the reasoning this was happening. *shrug*
The traction controller needed to ‘learn’ the tires and traction in winter to return to proper regen action. Whether this is by software writes or adjustements was unclear.
I have no dog in this fight, I’m just providing my opinion based on what I’ve read in this thread and elsewhere.
Currently have over 3000 km on my winter tires. No such learning and happened and I still don't have highspeed regen. Regen got a bit better with 2018.49.x at low speeds (city speeds) but no difference noticeable at highway speeds.

Just installed 18inch Tesla S style rims on my 3 with conti SI 225/45 and same here no Regen till below 50 and much better below 30 but not all the time.
The car will not learn the new tires never had to learn the all season it came with so don’t even expect this.
Note I am on 49.12.1 software
I tried Regen to low and then back and nothing.
Here’s hoping version 50 will do the trick as others have reported.

I want to add. It is almost like these tires actually have zero grip.
It’s kind of scary.
Even from launch zero to 60-70 the whole time the anti slip is going crazy.
Not liking this at all.
Car is also pretty squirrelly on the highway just 105 autopilot

I've got the same tires (on stock aero rims), but haven't had any issue with grip or launch. How can you tell the anti slip is going crazy? Maybe I'm just not noticing it? But I certainly haven't noticed the tires having an issue with grip going around corners. I came from X-Ice 3's on my past 2 Volt's, and the conti's feel pretty much the same to me, though admittedly we haven't had enough snow to really test them in all conditions yet.
Are you sure the rims are properly balanced and installed? All lugs torqued properly? Almost sounds like that might have something to do with it...just guessing....
I have the Continental WinterContact SI’s in 235/45r18 and my experience is totally different from yours. Car drives fine, even in the snow we recently had in GTA. The tires feel a bit more squishy compared to the stock all seasons but that’s to be expected given the winter rubber compound. I have not had any issues with “zero grip”, “anti slip going crazy” or “squirrelly” behaviour on the highway. Sounds like you may have some other issue?

The anti slip “yellow icon” I guess a better word is traction control. Punching the car it pretty much is on the whole zero to 50-60.
The place I get my tires done are very reputable and I have used them for many years. They only do high end cars.
It feels like I am hydroplaning probably the best way to explain it. I will do some test tomorrow when the roads are not as moist/wet like today.

Definitely right direction, and I asked them to put the PSI to 44 as I thought this is what they should be for winter?
Maybe this is the issue?

Got upgraded to 2018.50, and it’s much improved it’s pretty close to being back to normal. It behaves slightly differently as you can see it pulsing the regenerative breaking just slightly
