Recently replaced my original tires with Pirelli Cinturato P7 All Season+2 and absolutely love them. I bought the same size as the original tires (235/45 R18)...I considered upsizing slightly but the price was about $200 more so I stayed with the original size. The OEM tires were going to be about $1,000 at the dealership so I shopped these at Tire Rack and got them for $683.20 delivered. I've never had Pirelli tires before but now won't buy anything else again. Fuel mileage is unchanged....I make the same 420 mile round trip several times each year, starting with a full battery and driving in HV mode. Actual measured mileage remained unchanged with these new tires, and they ride so well and the car handles great with them. HIGHLY RECOMMENDED!
