I have a 2013 WK2 SRT8 with 70k miles on it. I recently have been having a humming/vibration at 35-45 than off 45-55 than 55-65 than off again. I just put new tires on it. Toyo proxies st iii and it feels like since I put the tires on it's made this noise. There's no grinding or metal scrapping noise so I'm not sure what going on. It goes away if I turn left slightly but still there if I turn right. Any insight?
