Steering shakes on concrete freeway around 65 mph

What is your question?

All web reading state this a common problem. have not been able to get a solution. Good Tires and wheels. Oz 20inch alloys Pirelli scorpions 275/65/20 have not tried rebalance but other posts state that is not a fix. 45000 miles. Bilstein 5100 series struts. If you have any info it would be appreciated.
