What he said, lower rear pressures should help the rear stick.

That is, IF your pressures all around are near their sweet spot (or higher) for pressures... if, by chance, you were already running pressures on the low side of the sweet spot, then lowering them further could give you even less rear grip.

Sounds like you're in a good place for the Azenis. Lower rear pressures should be the ticket... or at least an improvement.

Don't forget alignment. How adjustable is your suspension?
