One of my explorer wheels is cracked. I barely hit a curb the other day I go to check the tire pressure today and its cracked. I have the tpms. I seen that there is different wheel model numbers does anyone know what wheel I need? Can anyone remount the tpms. What about aftermarket wheels any updates on these issues. My local dealer isnt the best by far. It also makes a humm sometimes when accelerating but stops when yopu let off the gas anyone know what that is?
