I oft complained of noises from my car...I cried about a potentially bad fuel pump, or the exhaust pipes possibly coming into contact with something...Wrong! It's the freakin' tires...just had the tires rotated and balanced...verdict? The tech told me two of the four tires we're producing enough road force to cause the noise...road force..wtf is road force you might be asking yourself? It means the tire is for shit...it is out of round or it has a very heavy spot at some point in the circumference...these tires suck and it seems like it was a cost saving measure by Ford to have them as OEM....well, considering how much I have spent on mod parts so far, it won't hurt to trash these tires immediately after only 6000 miles, and at least I have diagnosed the problem, which was honestly driving a bit madder than I already am...and I won't even bother going to the dealer for a warranty claim...I will just buy new tires...because I don't want new tires from Ford that I know are already garbage..Tallyho!
