Ok i don't know which tire it's coming from but there is a descently loud humming noise coming from my tires...sum people say it's my alignment and sum say its the wheel bearing. Also there is a ******* annoying as hell buzzing sound inside my car. I can't figure out what it is and it's coming from the back seat area. any ideas on how to fix the noises?

 

Hmmmm... Is the noise like echoing? Humming. What tires do you have? And the condition or how much life left? I had these ultra cheapo tires from Sears and they hum really loud at 50mph.

Buzzing I could guess comes from the fuel tank area. Maybe fuel pump? Did you strip your car of any sound deading materials?

 

could the buzzing be from a speaker?
