Tire Pressure Monitoring System Problems of Chevrolet Silverado 2500

Excessive rear tire pressure in tires on rear axle causes loss of traction and the rear end to skid out in wet conditions. 80 psi is fine for heavy loads, but on a empty pick-up it causes a small tire contact service area. I have easily corrected the problem by reducing the rear tire psi to 50 psi which solves the problem and still is more than needed for a 2900 lb load the problem is this turns on the tpms light making it useless. I have seen more than one o these pick-ups loose controlandrollover as a result of this excessive tire psi on unloaded pick-up trucks that had 80 psi in them.

The tire pressure monitoring system requires a pressure of 80 psi in the rear tires of the truck. This is very excessive unless you are hauling a very heavy load. Unloaded, this causes a donut shaped tire and causes severe cupping in the tire wear. Gm will not lower the threshold at their service department. This also creates an issue if different tires are put on the vehicle that require a lower psi. Load range d tires require less than 65 psi, so even at max psi these tires are over inflated. With either tire, the threshold is too high. The system tells you that you have low tire pressure if you inflate the tires to a proper unloaded pressure. At the suggested pressure, not only is tire wear greatly intensified and uneven, only the center part of the tire makes ground contact causing easy traction loss in the rear end, especially in wet conditions. This high of a pressure unloaded also causes an even harsher ride than normal. Taking this issue to the dealer (mclarty in huntsville) to get a proper threshold set resulted in a run around. Not only do I lose my ability to know if I have a flat tire (system always shows a low pressure), I lose my ability to put on a better quality than stock tire (which requires less than gm required 80 psi to not set off the tpms alerts), and my tires wear abnormally and very quickly. Also my traction is very limited when not towing a load. The customer should be allowed to adjust for the tire pressures that apply to their application. I have already ruined one set of stock sized tires that were over inflated. This is a gm problem that keeps getting flushed down the drain.

I purchased a new 2007 Chevrolet Silverado 2500hd from dewey barber Chevrolet August 2008. After the first tire rotation (approx 5,000 miles) the service tire pressure monitoring system message displays onto the instrument panel. I followed the instructions step by step to relearn the tpms as outlined in the owners manual but the system will not reset. I carried the truck back to the dealer (2 times) and they reset the tpms however they did not fix the problem. I just rotated the tires again and the service tpms displays again. I carried it back and they kept the truck 3 days. They replaced 2 sensors, reprogrammed the computer and replaced a multi-door module that did not correct the problem. The service manager called me back today and said they contact gm and no fix is available. This should be fixed. It reports the wrong tire inflation through the star service that I pay a subscription not to mention taking the truck back to the dealer every time I have the tires rotated. Also, the instrument panel displays this message ever time the ignition is turned on. Your attention with regard to this matter is appreciated.

The contact owns a 2007 Chevrolet Silverado 2500 hd. The day the contact purchased the vehicle, he noticed that the tire pressure in the rear would not allow the vehicle to obtain good traction. The dealer stated that he could adjust the pressure, but the tire pressure warning light remained illuminated until the correct air pressure was placed back in the tires. The contact feels that he should be able to adjust the pressure without the warning light illuminating. The failure mileage was approximately 5 and current mileage was 20,000. Updated 5/19/08 the tire pressure monitoring system is set so that the rear tire pressure must be 80 psi. While this is appropriate for a full load condition, it is far excessive for an unloaded situation casing severe loss of traction and also excessive tire wear. Updated 05/19/08.
