The contact owns a 2014 Dodge Ram 2500. The contact stated that the rear tires had a required pressure of 80 psi, and the front tires required a pressure of 65 psi designed specifically for hauling. However, the vehicle was not used for hauling at all times. The contact stated that when the vehicle was not used for hauling, the over inflated tires bounce, causing the tire monitoring system to illuminate. The manufacturer advised that the tire pressure was unable to be altered since that was how the vehicle was designed. Therefore, the dealer was unable to correct the tire pressures. The failure mileage was 1,000. The VIN was not available. ## VIN failed ## Dodge Ram 25000 ##

Tire pressure monitoring system & Firestone transforce ht 275/70R18 tires I have had numerous problems with my tire pressure monitoring system and tires. My testing is finding a tire pressure variance of up to 15 psi between hot and cold pressures. Originally my truck would give me a tpm warning message with 3 psi variance. Now it has been reprogrammed by Chrysler so it requires a 15 psi variance. This concerns me as such a pressure variance places my rear tires at 94 psi. I am very concerned that these tires will break down and we will see a repeat of the 1980's Firestone tire problems.

TPMS does not allow setting tire pressures to either the oem door sticker setting nor the recommended tire setting from the tire manufacturer without setting warning light and nag screen on startup. Constant warning light and nag screen correction will lead to driver complacency, negating the purpose of TPMS alerting the driver to a potential problem with the tires. TPMS required overinflation results in potential loss of vehicle control due to loss of traction. Abnormal tire wear due to tire overinflation increases risk of hydroplaning and loss of control of vehicle. Ram customer service has been contacted and confirmed that this problem is systemic, by design, and can not be corrected at present time. Potential fix is to reprogram BCM, allowing dealers to reset TPMS to appropriate setting for tires and actual load with appropriate documentation. The rear tires have to have at least 80 psi, a condition of over inflation without a maximum cargo load. This makes for poor control on wet or icy roads and leads to premature tire wear.
