I'll reset the trip meter now that I have the Indy 500 on the car to compare mileage before and after. The old tires were worn out to 7mm less radius. If trip meter runs on wheel revolutions and not gps, the consumption can't be compared. Does anyone know what trip distance is based on?
Is it weight rated for a Tesla? Just because a tire comes in the size that can be mounted on a Tesla doesn't mean it should be used on a Tesla. Does the manufacturer recommend it for a Tesla? In my time on the forums, I've not seen that tire mentioned.
I had them on my prior 2008 IS350. Tires were quite good, except I didn’t think they were great in the rain. Other than that, I’d give them a thumbs up.
Eagle touring.
Actually - I just submitted the current rebate on the Firestones which make them $133 per tire. For a performance tire that size? You can't go wrong.
I have had them for 455 miles now and got 318 Wh/mile. OEM (Eagle RSA2) tires used 305 Wh/mile. Not sure if I drove equally so please take this with a big grain of salt. The ols tires were worn down to smaller radius. If trip meter based on radius, take an even bigger grain of salt. Only if GPS based is this result useful

I just read this thread: Do P85Ds and S85Ds have inaccurate odometers that overstate distance traveled? where it is explained that the trip meter uses wheel revolutions. Since my OEM tires were worn down 6.4 mm from new from a 350 mm radius, the OEM wheel consumption becomes not 305 Wh/mile but 310, to compare with Firehawks' 318 if everything else was equal.
I don't know about quietest.. but I just put back on a new set of OE Michelin mxm4 after having run winter Michelin Xice... and the mxm4 are very noticeably quieter tires than the winters. Plenty quiet for the car.. If model S was a quieter car with more sound deadening etc.. it may be worth hunting around for quieter tires yet... but these are a good match. Put a smile on my face.
