Just avoid Active Green and Ross. I just had a tire replaced by Tesla (flat tire with damage to the sidewall), but tried to get a quote from AGR who are nearby. They would only sell me a set of 4 because "it's recommended by the manufacturer" and "it'll damage the transmission". Even though I explained there's not a driveshaft, they stuck to their guns. Never asked mileage, wear and tear, or anything about the tires that might lead to this conclusion, although I gave them the opportunity to explain it. I'll keep taking my business elsewhere. Tesla replaced the single tire - says it all.
Scam artists at best.
