…the ET34 are intended to maintain the correct scrub radius for vehicles with what was originally called the Performance Upgrade Package, while the ET40 maintains the correct scrub radius for non-PUP vehicles.
Correct to do what?
Function as designed:

Ps- to the person asking what tire I went with, I put that in a previous post: 255/35 Michelin Pilot Sport 4S retail version (purchased from Costco with rebate for total installed price that was $50 more than what I sold the 4 new 235/35R20 PS4S TO for on FB marketplace).
After approx 4kmi, I’m running 310Wh/mi. The OEM wheels/tires I had 314Wh/mi efficiency over 27k mi but I’m doing a lot more local driving than before. I’d guess if all were equal, these would only be about 5-10Wh/mi worse than the stock 20s.
