The "best" advice I have read was from the "other" site, in response to a problem where a truck wants to do a "360" on ice. (Somehow, I think he meant a 180, but whatever.) He was advised he should air down his tires in winter for better traction.
I may have read WORSE advice on an internet forum somewhere, but that one is right up there!
It is almost as bad as someone noob telling another noob to make sure you always put the new tires with the best tread on the FRONT of the vehicle because the front tires need to turn.
Keep your tires well inflated in the winter. Most P-metric tires get their maximum traction at 80 to 90% of the maximum pressure as listed on the sidewall. In winter, it is better to go towards the upper end of that scale. (Make sure you measure the tire pressures COLD; maximum sidewall pressures already account for the increased pressure when warm. The listed pressure is for a cold tire.)
The other issue with Stabiltrac that will be a more and more common complaint in years to come is the various sensors that are required to keep it working, most particularly the steering wheel angle position sensor. I have never taken one apart but I speculate it has some version of a variable resistor in there and because one most often uses the straight ahead position while driving, the outer edges of the sensors don't get used as much and may not make as good contact. If you truck sits for a few days and especially if left with the steering wheel slightly off to the side, you may get a Service Stabiltrac warning light when you first start up. If you drive for a minute, turn it off and then restart the truck, it usually goes away. Very common problem.
Hey, we should get Roadie to research this problem some more. I would like to know what the sensor looks like on the inside.
