Is there any difference between Pilot Sport 4 and Pilot Sport 4 acoustic tyres?

this seems to be discussed a few times on the forum that its a rebrand of the same tyre

There’s an email from Hankook somewhere on here confirming that the tyres are the same. I still wouldn’t risk it though!

As someone living in the UK I have zero issue with this. As Tesla cost cutting measures go this seems eminently sensible.

Not sure it was even a cost cutting measure but more to make a tyre suitable for higher speeds means changes that increase rolling resistance. So by lowering the top speed, they could also put on tyres that reduce the rolling resistance. It’s all about efficiency I think but if it saves them some money also, even better I imagine.

Finally got 18" ION Evo's on, efficiency looks good so far on a 100 mile trip yesterday, and they are quieter (but I always find new tyres quieter than fully worn old ones)

I did a 470 mile highway trip on Monday and managed to drive 290 miles at 70mph (without A/C) before I needed to stop to charge with 6% battery remaining. There's a Supercharging stop 200 miles into the trip that I often reach at with ~22% SoC but I sailed past it with 33% remaining and drove a further 90 miles.

After the charging stop I drove the remaining 180 miles at 75mph and saw an average 259 Wh/mi.
