Attention: TDR Forum Junkies I have been wanting one of these gauges for awhile, so yesterday (Sat) I dropped by a local NAPA store and bought one. So far just on visual of my oem Michelins they still showed good tread wear after 2 3/4 years and 32K miles. I measured each groove and it showed 8/32nds across on each tire (new tires measure 15/32nds for the ones that don't know). I have kept them rotated every 5K except for this last oil change in which now the tires have 7K on them since last rotation at 25K miles. Also have tried different tire pressures since truck was new, currently running 60psi front and 50psi rears. It seems to be a handy little tool.
