lolz, well i still didn't replace the tires. the balance on the gsp9700 machine seemed to fix it.
but what's pissed me off i had the tires balanced at two different places before this wheel shop. so either those balance machines are WRONG, or my tires were just in need of a dynamic road forced balance opposed to the regular style.
EDIT: balance machine seemed to help it. got the tires checked out and sure enough the bands are separating and can be seen through cracks in between the treads. so, shemmy problem is in my tires
