Re: Traction control: How do I tune a PID controller with variable gain?
Are you using LabVIEW? If so, this would be an excellent opportunity to use some controls and indicators on the front panel of your VI when running in debug mode to allow real-time tweaking of gains to determine effect.

In general (very general), you'll always want to set Kp as high as possible (typically until the noise becomes unbearable) and then increase Ki until things go unstable. But I stress VERY GENERAL guidelines.
