Rhall77, thanks for the reply. The tires are not cupped. Just for kicks, I swapped tires with my friends Tahoe and it still had the same noise. I even replaced my front wheel bearing hub assembly and the noise is still there. I can turn left or right and the noise is still consistent. Once I go past 35mph, the humming sound seems to go faster. It actually sounds like a small airplane but not as loud. When I start to slow down the noise slow down. Other than the noise, my Tahoe drives like it's brand new. I have stock tires on there. No big tread. If I drive below 35mph, it's fine. Maybe my fan?
