No Regen after winter tire install

[Darthbenji]

New tires and wheels (replikas) went on today for winter. It’s a mild day and the car was in the shop for an hour or two. No dots on the energy bar to suggest regen would be limited. About 30% charge on the car and no regen at all until maybe 15 miles per hour. Then it kicked in. Drove straight to a service center and they seemed stumped. They said it could be the car learning the new tires and grip level.

Anyone have any similar experience? How long did it last?

I put on new 2018 set, had to purchase new sensors, the car recognized them immediately. I just taped RESET Senors. and they were read.

 

[Darthbenji]

So it was the sensors? Where is the reset sensors button?

I bought new sensors from the shop.

I’ve driven with inop TPMS and it has zero effect on regen/acceleration/handling. Just got a warning message until I got the correct ones. I kinda doubt that’s the problem

 

[Darthbenji]

So faulty TPMS won’t affect regen? Can aftermarket rims? Went with replikas. Still no regen today.

It’s more likely that the shop who swapped your wheels didn’t know how to properly lift the car and damaged something. In any case, Tesla service should be able to tell you what’s wrong with the car if you leave it with them. Though they’ll probably want to reinstall the OEM wheels as a first step.

Until 15mph? If increasing speed, this would be correct.
How are you measuring regen?

 

[Darthbenji]

Just to clarify what’s going on. Replika aftermarket rims and continental winter tires were installed. At speed you need to use the brake to slow. That’s with no dots indicating regen is limited. When you slow to about 15-20 the regen will kick in. Not before.
Has anyone installed winter tires and rims and had no change? This is happening even when the battery is warm and the charge is below 80%

I noticed the same effect after installing winter tires. Using Tesla 18” aero rims. It does not bother me yet, perhaps the car is indeed learning something about them.

How long ago did you install?

How long ago did you install?

Last week, and I drove about 200km since then

So it’s the tires then if you have the oem rims on still. Which tires did you go with?

I also went with Continental WinterContact SI like you

 

[Darthbenji]

Any change today? I wonder if other tires will do it also.

I got the same with the conti on my aero rims. Not much regen at speed but only when hitting the brakes more then it kicks in

 

[Darthbenji]

Anyone have it without the continentals?

How long have you had them on?

Yeah, I have been having the same issue with Michelin xi3’s on Fast FC04 18” wheels. When I release the accelerator at high speed I will get normal regen for a moment before it drops to almost nothing, then seems to resume normal again around 30km/h. Battery is warm, no dots indicating limited regen.

 

[Darthbenji]

Ok so that’s three different tires now. The xice, continentals and hakkas. All different rims. Tesla must know something about this.

A week now. It sucks because I got v9 + it's turned cold, so I can't tell if it was a software thing or because it's cold or the tires. Mine are on the oem aero rims just swapped tires. Could be something to do with weight as I'm sure they are different than oem.
