I just purchased 4 new Michelin Pilot Sport AS 3+ tires and the salesman told me the only difference between a “V” tire and a “Y” tire is top speed...I ended up buying the “V” tire as that was what the original tires were rated...Did I get duped??

The DOT requires tires rated for the top speed on the speedometer on a new car.

When they are replaced, you can, at your own risk, put the cheapest POS tires on you want.

V=149mph
Y=186mph

I'd say your fine.

Those ratings are for sustained speeds and the related heat, not momentary speeds.

I certainly don’t expect to reach 149 mph at all,let alone for “sustained speeds”...appreciate the info though....didn’t know if the rating affected tread,grip etc...
