I ran into an interesting problem. I just swapped out my rims and tires for newer Cherokee rims and 10 ply Goodyear Wrangler tires. The problem is that the 10 plies run at 80 psi. At first the system just showed maximum pressure, which is what I thought it would do. Today the tire warning symbol kept flashing and I received a message that the system required servicing. Can it be reprogrammed or shut off?
