Question about tires. Bought some Bridgestone Potenza 009's from a local dealer. Have purchased tires from them forever with good results. Had them on my '03 GS300 for 4 weeks and had to have them rebalanced about 6 times because of vibration from 70 up. They replaced them last weeked with a Bridgestone Potenza 092 or something like that. Well this morning driving into work, I felt a vibration about 75 mph, but it came and went and on some pavement was totally gone. The tires have less than 200 miles on them. Can this still be a balance issue? Both the dealer and myself are scratching our heads! Thanks!

i will toss this out there becuase i had the same issue with some RT615's. They are on a car i dont drive alot, anyway i have the same issue. However i was told since the car sits in my garage which last week was about 140 degrees for about 4 days straight that the tires actually sort of melted and flat spotted themselves.

anyway that is what happened to me, and that is what the tech at americas tire told me since the compound was so soft they did this.

I agree with the flat spotting, but in passenger car tires like mine, where the car is driven at least once a week, this should not be a problem. My truck gets driven about once everyother week and it has some flat spots but they go away after a few miles. On the 009's they replaced the dealer was thinking it was an issue of when the tires where cold, the tread was not secure on the carcous (sp?) and one it got warm/hot it would firm up. I tried changing pressure, from 32 psi to 40 psi with the only thing changing was how twitchy the car was. I am going to put the car in the air this weekend and see if I have some problem with other suspension parts.
