Tire 2 to 1

This is probably a obviously dumb question, probably self inflicted. Does any one else see a tendency to tire use 2 set on the rear to a set on the front? Possibly just my bad lead footed driving. I don't think it matters brand or wear rating. I am not seeing edge to edge variation or center variation. so I don't think its alignment. The car has had an alignment every year to keep it close so I can just bump the chamber for the track. I bump the Chamber with a digital inclinometer on a level concrete floor
  • PS2 to 2 sets on the rear and one set on the front. This was before my motor update. 16,000 miles on the fronts 9,000 first rears. The second set was 3/32 and 4/32 across when the fronts were at the wear bars
  • Conti sport Contact 2 6/32" left on front, rears were bald. About 3/4 of their life was on the 2.7 motor the last 1/4 with the 3.6 motor about 16,000 miles
  • My track RS3 7/32 left on front bald rears after 21 track days
  • The Sumitomo HTRZIII tires post engine update are doing the same just above the wear bars on the rear and 7/32" left across the front and 15,000 miles

I think that's pretty standard. Right now my rears are not wearing quite 2 to 1, but I'll probably replace them early just so I can get an entire new set the next time around.
