Vibration at 70mph

I am at 17K. I am enduring it for the next 3k and I hope to get that "smooth as glass" feel.

The rears that I got are Nittos. The fronts are Michelins (for now).

Laters!

BTW: I don't get the same vibration when the top is down--only when up or when I have the hardtop on. Is this the same for you?

It is not recommended that 2 different tires are used on the same vehicle. This can cause a harmonic vibration due to the 2 different tire's characteristics.
