You could have blown your tire or it could have gone flat.
it could be your tires on the pavement.
Noises have to be heard to correectly diagnoise. It could be bearings, tires or a number of things.
bad rotors
A bad wheel bearing
Probably a worn wheel bearing...have it looked at by a technician before it seizes.
Increased road noise, decreased fuel efficiency.
well, when you drive with any of the four tires being low you will cause it to over heat, or it could be making a lot of sharp turns.
Are the tires actually rubbing or do you just hear a noise? If they are rubbing you have a serious front end problem. If you are just hearing a noise it could be that your front brake pads are worn out. There is a little metal pad built onto the brake pads that rub when the pads are worn out, telling you that it is time to have them attended to.
if it is mounted on the drive end it will cause undue work on the differential and it could also cause some handling and stability problems tires should be replaced in pairs
Certain types of tires may cause a brief humming noise after your initial acceleration. The transmission may also cause a brief humming noise.
The sound you are hearing could be coming from bad Tires. As the Tires Feather because of misalignment or suspension issues, they develop an uneven wear pattern. If the noise gets louder as your speed increases, this could be your problem. Get to a Tire Dealer and have your Tires and Suspension Checked. :-) Another noise that sounds like a tire noise is a wheel bearing going bad. IF you take you hand and feeling the tread around the tire, you can tell if there is a smooth feel or a wavy feel or choppy feel etc. Anything other than a smooth feel could cause a roar. IF your struts are original, they may be causing a choppy wear.
Defective left front wheel bearing. Have this repaired ASAP, as it can cause an accident.
