I ran stock pressures for the last 2 years and rotated my Pireli Scorpions AT+,tires every 5K. I had great wear on all tires. +- 1/32". I really think that weight in the rear is the only wildcard for reducing pressure, other than off roading.My van weighs in at 8200#s. Winter traction IMHO,seems to be much more dependent on the tire makeup. I.E. winter tire with softer compound and tread design.Just curious what pressures others are running at on their 245/75 tires, especially for the snowy conditions ahead?
