Tire making noise above 85 mph

Not that I should be driving > 85 mph, but I live in Texas. the speed limit is 75. quite often I go above 80.
I noticed there is some tremble noise once I am above 85, and become quite obvious if I am at 90. that just happened once so far lol.
I think it is coming from tires.
should I be worried?

When's the last time you had your tires balanced and an alignment done?

I went to a local shop and did tire balancing on all four tires, I am still hearing the noise sometimes when I am above 80 mph.
by the way, I live in the country, so speed limit is high.
So what is the next thing I can do? replace tires?

What is the speed rating on the tire, or what is the type of tire you have on? (All season, winter. Etc..)

Drive slower.

How many miles are on the tires? Are you sure they all have the same air pressure in them?

It could be the pavement you're driving on. Usually concrete is louder than asphalt. And some tires are louder than others. Maybe at times you're tire & pavement combination is just loud.
