Re: My Trailhawk Mods...
Chunderboy - When the new tires and sensors were installed last week they said they put 40psi in them to start. After I drove less than 2 miles the all the sensors were reporting in, but there was a difference of 2-3 lbs on each corner. So the next morning I checked them cold, temp was about 45degs. The PSI range was 36 to 39, brought them all up to 41. Basically just a random decision although I wanted to see what the ride was like. I then drove some freeway and city streets and the TPMS display read 43 on all four corners.
I've tended to run a little higher pressure on M/T tires on the street, particularly on the fronts. This seems to help slow down the cupping on the outside edges.
As for the "Hawk", I'll probably back them off to about 36 and see how they feel.
