@outdoors, which model 3 do you have?
I'm looking for light wheels that allow for tires with more sidewall. The fact that 18" tires are cheaper is a bonus. I figure that black wheels with the minimal spokes will look sweet over the red calipers.
I'm certainly not worried about things breaking if we push the wheels all the way back out to the factory setting (aka +35) on my P3+.
If we can't swap to the +35, I'll probably cancel and order the 18" TST +35 wheels. While they are 2.8 lbs heavier than these, I assume they are more aerodynamic as they are a copy of the old Model S wheel spoke styling. In a street wheel perhaps the assumed better aero would be more useful than the lightness. (Sure would be nice to have data to inform our decision.)
