hi,

i was driving on hwy yesterday and noticed a weird thing - fairly strong vibration @ 85 mph, starting @ 80 and increasing with speed.

i felt it with the steering wheel as well as my seat.

my rear suspension was worked on last year and steering damper(?) was replaced as well.

Could that be tires? my front ones are old, but still have enough groove...

your opinions are appreciated, as always...

thanks in advance.
