Cooper discover a/t 3. So they are definitely not a mud tire.

Is it normal for them to be hot and not have bad hubs? I have tried turning the wheel both ways and the humming doesn't increase one way or the other. Could it just be tires noise/needing an alignment I'm hearing as the tire wear? They have about 20,000 miles on them currently.

I have 60,000 miles on my gmc sierra I've been hearing a humming in the front end along with checking my hubs occasionally. They are warm after any hour or so of hwy driving. I've jacked it up and there was zero play, but since the hubs were so hot I decided to change one wheel hub. I put 500 miles on this last weekend and the noise isn't any better and the new hub is still warm. The rear hubs are cool to the touch. Any info would be greatly appreciated. Thanks
