Michelin Super Sports, approx 12K, plus 12 days of DE.  They're chunking on the left frt.  Had a DE last w/e.  They looked OK on Sat (I checked b/c someone else with same tire had chunking issue).  Was having trouble with tires hooking up on Sat, so experimented with lowering pressures.  Eventually settled on 3 lbs less / tire (29f, 34r, both 3 less than recommended).
So with all that info, did the lower pressures cause my issue or was the tire maxxed out from too many DEs?
And I have 2 day DE at Kansas Speedway this weekend.
