@MetalgaffThanks, could you also mention the tyre make before replacing and after replacing ?
In my case, I have dunlop 205/55 R16 which has been used for 35K Kms, I hear some sort of boom sound as I accelerate past 30 kmph range and also while I deaccelerate.. The sound increases and stays.. but the worst part is that I cannot talk to others at 90/100 Kmph,, neither can listen to music.
