Just checked the tread on my Nokian WRG4's and down to 4/32 after only 17K miles!
My previous tires were Michelin MXM4 (OEM) and then A/S3+. I got between 25-30K on those. The guy at Discount Tire said that's typical for Teslas, as the Nokians have softer rubber than my previous tires. They were great in the snow, so my feeling is to stick with them. I did ask about the Michelin Crosscountry2 and he said wear will be similar to the Nokian, as it has a softer rubber, too. I am getting back about $150/tire for the treadwear warranty.
