I just installed the 2002-05 RAM 1500 4WD 6? PERFORMANCE SYSTEM made by Fabtech and put 35x12.5 BFG MTs and 17x9 MT classic II rims (see pic here:
2). I have a vibration at 40-60MPH that is not very nice. (no changes were made to the rear drive shaft, etc....)What components could cause this? I had the tires balanced and they used the stick on lead weights inside the rim. Are tires this big able to be balanced like that? I thought there was something that goes inside the big tires that balances them.
3). I had the dodge dealer recalibrate the computer / speedometer to compensate for larger tires. Now the cruise control only works up to 45MPH (I can only turn on cruise below 40 MPH and then using the buttons on the steering wheel accelerate up to 45MPH before it shuts off). Again, I returned it to the dealer and they says it's not the computer recalibration. They have never heard of the problem. I know it has something to do with the big tires and the computer recalibration, because the cruise worked fine just before the recalibration.Any help or advice would be appreciated.
