I will interject my two cents worth. I agree with Tegger as to the probable
cause of the wobble but I would suggest you go back to the tire store which
mounted the tires and have them check for out of true tires and/or wheels.
This can be done on a dynamic balancer either by eye or by using a marking
pencil held perpendiculat to the direction of rotation against the side of
the tire. An out of true will result in the tire contacting the pencil only
in places as it spins. One further suggestion - if an out of true condition
is found, have them dismount that tire and check the wheel for true using
the same method...
