Ok today I was driving my stock Rex to work when I started to hear a hmmm sound alot like the hmm you hear when you back your car up lol... but it only does it when I go over 35 mph or so.. and only on the right side.. any ideas on what could be causing this my tires have about 10% tread left could this be causing the issue?

 

Sorry for the bump but I need some help

 

Hmm, wheel bearing? Try jerking the car side to side when the noise is there, and see if it changes.

 

This almost sounds like the problem I was having a while back. Mine was coming from the center of the engine bay, though.

Try adjusting your timing a TINY bit to the counter, as this could be "Rotary Detonation." Or something like that.

Even if your tires aren't the problem, CHANGE THEM!!!!
