it has been about two weeks since i noticed this... it is a loud annoying noise, its road noise but only louder than usual and it sounds even louder when slowing down. i got an alignment when i lowered the car almost 9 months ago. could it be alignment issues. the rear tires have slight feathering but not much....can this be it. and plus the sound sounds like its coming from the front. .........

 

Hmmm... sounds like a classic case of tire feathering. If the alignment wasn't done accurately, you could easily be developing feathered tires up front.

 

How many miles are on the front tires?
Have you looked at the inside tread?
The noise has been getting progressively worse correct?

 

yes the noise has been getting worse. and its getting to the point that its causing a little bit of a vibration inside the car. i was looking at the wheels and tires and noticed that there is no feathering in front tires (some in the rear) but did notice a tiny bend in my front passanger wheel. i think i remember when that happened, i hit a big pot hole. could this be what knocked everything out of alignment? oh and there is a bout 10k on all tires. btw i added rear spacers on my set up... that shouldnt throw alignment off correct?

 

If the alignment was done in San Antonio, it was probably done wrong. Check close for tire wear and if it is minimal take it to Soul Speed or some place comparable elsewhere.
It may pay to change L/F to R/F---R/F to L/F tires keeping in mind rotation, and have them re balanced at that time.

Also tire roar can be caused by belt separation that can be determained by a CAPABLE tire man. If he's good, he can run his hand over it and feel it

 

Belt Separation

 

sorry, but does this mean i would need a new tire? or what is belt seperation?

 

If you have belt separation you need a new tire. There are woven belts embedded in your tire that give it strength,rigidity and its Round shape.

Bias tires ran belts wrapped perpendicular to the circle, Radials run belts that are paralell with the circle. If it tears, either from a defect or HITTING something, then you lose your "round" and the more it separates the worst it gets til you have more and more vibration and eventually a Blow out.

A good man with a Balance machine will be able to tell ( It wont Balance)

ALSO.... A belt can be torn from a sloppy install on the rim

VERY important to have a good specialty shop do your work and not some minimum wage grease monkey

 

I had that exact problem. I bought a new set of tires and got an alignment...problem solved. (I was experiencing the "tire feathering" everyone else has been describing)
