yes, I went back to the store and all tires were re checked
as result driver tire was off balance - as I was told - not by much, but enough that Lexus car feels vibrations (too delicate car) - it was explained to me
3 others were perfect
strange as the store has balancing machines - why not to do it in the 1st time?
after re balancing was done I don't feel vibration as it was before, but I didn't ride much - just got back home through traffic
will ride more tomorrow to be sure it's gone
It could be a tire out of round, I have notice this more and more with tires sold today. If the ballancing is not the issue, I would take back and make them check for high spots.
