I have a noise coming from my right rear tire... when going low speeds its sounds like metal on metal... I inspected the car and suspension looks tightened so can't be from that...I pulled on the tire a couple of times and I heard the exact same noise like something is loose...No aftermarket wheels ....Any opinions ?

 

it may be the exhaust piping hitting the heat shield

 

Brake pads? Bearing? Remove the wheel and spin the hub and see if you still hear the noise.

 

r00s rugknuts?

 

I had a similar noise on my R at the Peru Tour this year and found our I forgot to tighten the front right lugs. DOH!!! Check the lugs and make sure they're tight!
