Humming Tires

I just had my tires rotated last month,lately,the front tires are
making a humming noise after 30 mph,is this from being on the backs?,a
wear in thing?. Thanks.

 

Some times rear and front tires have different air pressure
requirements. Check that first! For some reason, when my saturn
dealership 'checks' my tires the OVER inflate my rear ones. Yeah,
professionals.

Also, I'm figuring that since you rotated the tires, you checked wear
paterns and ruled out any serverely abnormal wear paterns(indicating
bad alignments and damaged tires), so you might have some small
abnormal wear paterns(like cupping wear from wrong air pressures).
The point of rotating tires is to allow even wearing of the patern, so
I would just give it time and let it get in the groove. Just monitor
over time and see if it declines.

I did check the tire pressure & they both were almost 40 pounds!,&
firestone did the rotation!,I let air out a little ,but they still do
the hum.they must of worn differently when the were on the back,there
was no abnormal wear on any tire.thanks againOn Sun, 15 May 2005

 

Were they rotated across sides or were they kept on the same side and just F
to R? Some sport tires require they be kept on the same side.

Were the tires cold when you checked the pressure? Are they a stock
spec tire? When I put ContiExtremeContacts on our '96 SL2 the stock
tire pressure settings weren't adequate. Way too soft at stock
pressure.

40 Pounds! I'm guessing these aren't low riders either.

Well I had my tires checked and they too were over inflated. This
caused the center of the tire to wear more than the edges. When I
fixed it(after driving on them for a while), they 'cupped' and I
noticied a strange noise comming from them. Thought it was a bearing,
and after some checking around, the mechanics said the 'cupped' tires
will make noise till they wear down even. I watched the pressures and
rotated the tiries, and all is find now.

Ok, if you don't think it's the tires, then a good guess could have
you leaning towards alignment or bearing issues. I would jack the car
and rule out bearing and rubbing components, but that's me. So, you
have to make the guess now.

Sorry couldn't help futher,

Wow saw this post and I completely forgot. Check for direction marks
on the tires.

Good job Bob!

They're probably humming because they don't know the words!

 

Either that or they're off of a hummer
