New Performance tire for Rocket 2.5 from Metzeler

Sounds like more likely a case of getting used to the bike & experimenting with tyre pressures.
Lot of torque, easy to break the rear loose on new and old, i ride with guys tgat got the buttons and modes and stuff and they break it loose anytime they want, or should i say showing off. Monster torque, especially on the new ones.
 
Have you ever had the Wheel/Tire Assembly checked for 1) Out of Round and then; 2) Checked for Balance?

The most common case of "Tire Cupping" is a wheel/tire assembly that's out of balance and/or out of Round.
 
Thanks Sunny,

Do you know the Tire's Compound Specification/Rating?
