Swapped wheels = less regen + lighter steering wheel

[echelone]

I just swapped my 20" Slipstream factory wheels to the Tsportline 20" wheels.

Post-swap, I am noticing two things:
1. Steering wheel feels lighter than before (Sports mode)
2. Regen braking is now less stronger (Normal regen)

Trying to figure out what caused the above. Wrong torque on wheel lugs? Something else the tire shop overlooked? Difference in weight on the wheels?

Not surprising if you have less rotational mass ... what are the new wheel weighs?

New wheel weights

Front - 20×9.0″ = 32.8lbs.
Rear - 20×10.0″ = 34.8lbs.

Should not be much different than factory ones?

any noticeable change in range? This is probably the wrong time of year to tell with winter temps swinging all over the place I'm sure HVAC usage changes day to day.

Here are the OEM wheel specs ... you are right between the 19" and 21" wheel weights
The Tesla Model S Wheel Guide - Tsportline

19″ Slipstream Wheel

• Size: 19X8.0″
• Weight: 29 lbs

21″ Turbine Wheel

• Front 21×8.5″ = 35.2 lbs
• Rear 21×9.0″ = 38 lbs

Same tires?

Same set of tires. Slightly better range now actually. May just all be in my head

Lighter wheels = Better range. Tires aren't as big a factor as the weight of the combination.
