Tires: tires, michlen tires, inflation pressure

Question
I have a set of Michlen tires, they will be 2 years old in december. the tread still looks good, but lately they have been humming ,loud. I am a realtor and take people in my car often and yesterday even my clients noticed it. what sould I do. thanks in advance

Answer
Corrine,

First, let me make an educated guess as to what the problem is.  It is probably irregular wear which is caused by misalignment and aggravated by insufficient inflation pressure and insufficient rotation practices.

If you absolutely want to eliminate the problem, you will have to replace the tires.  No, this would not be covered by the warranty since the cause is the vehicle misalignment.

Just for information, it is possible to rotate the tires and wear a new pattern into the tires that would eliminate the irregular wear, but in all likelihood, the vehicle would vibrate until the new wear pattern has pretty much erased the old wear pattern - says several hundred miles.

Hope this helps.
