Tires and springs will help.

Taller tires, 18" wheels
265/65R18
softer springs, looser shocks, and softer swaybars from a Tahoe NOT-PPV will help.
If 20" wheels are required to clear PPV brake rotors & calipers,
then you may be forced to downgrade to NOT-PPV brake package.
Problem is you bought a Police Pursuit Vehicle.

Your Tahoe was probably issued a firm suspension package for better handling. This can be verified via your RPO sticker

Nothing to do with K9 units. Everything to do with PPVs:
Police Pursuit Vehicles with Z56 suspension.
Most of us already know that most Tahoe suspension & steering systems are NOT designed to chase other speeding vehicles;
Tahoe PPVs being the glaring exception.
Solution is to alter the PPV so that it is more like a civilian Tahoe, see my previous post.
Saying 'Police Pursuit Vehicles have a problem' due to the way GM tuned the PPV / Z56 suspension, is like saying
'it's so hard to shave with a zweihander'.
Typically the Special Service Vehicle (5W4) is better suited to typical civilian ride expectations than the Z56.
