I've had these BFGs (185/60/14) for about 20,000 miles now and recently they've become VERY noisy and loud. I filled them to the recommended pressure and it didnt go away. It seemed to have been coming from the right rear, so i got my tires rotated and if anything it seems to have gotten louder. Its so loud that it gives me a headache and i cant hear my music or exhaust, and gets louder the faster i go.. Maybe they need to be rebalanced? ANY help will be appreciated.
