Just put on Pilot Sport 4 All Seasons on my '11 LS. Fantastic tire! Great handling & very quiet with 45k mile warranty, Got mine at Costco. $925 OTD. Standard equipment on new base model Vettes.

 

I have similar tires on my LS and A8, it's hard to ever go back after experiencing these types of tires.......though I will admit they are not the quietest.

 

I got Continental PureContact LS not so long ago. I used same tires on my RAV4, and I was pleased with them.
