Sounds like operator error.
Wheels/tires won’t have any noticeable effect on regen braking.
Learning appropriate EV accelerator pedal control will, though!
That is extremely light. Put the Pirelli PZ4 tires on those wheels and it would be hard to get even lighter than that.
Have you ever weighed new vs worn tires? There's several lbs of rubber weight I think and I was considering looking for a worn out set.
I weighed the 245/40/18 Pirelli PZ4 tires before and after 6,800 miles of use. They weighed 22.0 lbs brand new and 21.0 lbs used after the 6,800 miles. They still have decent tread left though.
It really is amazing that you can post a time like that with a wet road. No ICE car would even attempt that. They would all end up in the ditch.
The consistency of EV acceleration really is amazing.
Do you have any data? What was your battery max and min temps, f & r stator temps? Any dragy graph?
Did they give you a time slip with the intermediate times on it? Let’s see that if you have it.
Are you certain the timing system is accurate? I assume that because of your spelling of “tyre” you are in a country that uses the metric system. I have seen 1/4 mile timing be off in countries that use the metric system because the conversion is sometimes not precise enough.
I always run the Dragy as a backup even at the track because it is so consistent. You wouldn’t believe how many tracks have flawed timing systems.

I hate to ask but how much do you weigh? That can make a significant difference if the driver is extremely heavy.
The single most important thing for the 60 foot time with a Model 3 Performance is weight.
100% stock I did 1.82 60’.
Stock with a 100 lb passenger that went to 1.87 60’.
Preheating the battery didn’t improve the 60’ at all but lowered the 1/4 mile by over .1 seconds. 1.83 60’.
Using lightweight 18” wheels only took the 60’ down .05 seconds to 1.78 60’.
Taking 150 lbs out of the interior got me another .03 seconds over just using lighter wheels. 1.75 60’.
Really solid trap speeds. You definitely got the battery optimized. I wonder if they were including a 1 foot rollout or not? You definitely were losing everything in the 60’. All of your trap speeds are fine.
Try shallow staging. If you can stop just after you light the second bulb then that will give you the longest rollout and keep your 60’ time low. Everything else looks good for your run. You were hitting some really solid speeds.
More information - Driver weight 150lb. Ambient temp - 77F
About the only think I can put it down to is being unable to avoid the water box, even though we did a dry hop up to the line.
