Okay so when im driving above 30 MPH on the right side, it (sounds like its coming from the rear) starts to make the rumbling noise, like there is something lodged in the tire. Well i have checked the lugnuts, and they are not loose, i have checked the tire and there is nothing in there. the faster i go the louder the sound becomes. IDK what it is, but it is really annoying

 

maybe a worn bearing, or seperated plies in the tires.

 

Have you tried looking the tire over?

 

try putting on different wheels with tires on ,if it doesnt to it then your tires are bad,i had that happen to me,if it dont stop then go a head and check if its the bearings

 

Well the thing is, they are BRAND NEW tires. I got them a month ago with the rims. It was making the sound before i put the tires on too. So i will check the bearings. It still may be the plies, but i will check everything just to make sure. Thanx for the input guys

 

bump UPDATE!!!
So i checked the bearings and it was nothing....im starting to think it is the plies in the tires, how do u inspect that? The tires are like 1 month old tho...

 

okay so found out....that my car was having that rumbling sound because the douchebag that traded me the R1 suspensions....gave me a crappy rear shock. From this point on i am buying new performance parts. Thanks for all the help guys
