As I said before I had the AS3s on my prior IS350 and loved the tires. Wicked performance in different weather conditions, reasonably priced and great warranty. I am really looking forward to putting them on my f-sport when my potenzas are done. Keep on providing updates if you can, I would like to hear more first hand info from someone with the same car as mine. I did 170k in my IS so went through all kinds of tires, and these ultra high performance all seasons were easily the best for the price.

 

I put the same tires on my car back in mid-December and have about 2500mi on them now, I can report pretty much the same thing as you. My car's OE tires were the Dunlops. They were good when new but from about half wear on, they were terrible. They handled well but they were loud as hell and horribly uncomfortable, the car felt like it was rolling on wooden wheels. And they went slightly out of round over time causing vibrations as well. Going to the AS3+ is a night and day difference. Car handles much better in wet, and at least as well in dry, the tires are quieter, and A LOT more comfortable. MPG is the same, speedo seems accurate. I'll definitely get them again next time (unless of course Michelin has a new version at that point, which I'll just go for that instead!).

 

ItzFilyO any update on these tires?

I just placed my order from Tirerack for these tires since Michelin has a $70 rebate. It was basically free shipping.

 

I have almost 10K miles on them and they're great. I'm pretty sure the change in acceleration feel is just in my head cause the car feels quick again now. I don't think it ever was slower or maybe it was just the break-in period.

 

Awesome. Can't wait to get mine installed.

 

You went from worn out stock size to new bigger size. That's roughly 1/2" taller tire, which you may be able to feel in slower acceleration. During cornering the wider, newer tires should have more grip at the limit, but may feel less "nimble".
