Had the tires on my 13' screw rotated about a week and a half ago. Recently hearing a humming type sound when the tires are rolling and nothing when stopped. Seems like it's coming from the rear. Any ideas?

Thanks

had many miles before rotating and did they crisscross them. probably just your tire singing some, need rotating every 5-6k miles.

How many miles since your last rotation?

I would venture to say it's just your typical road moan from your tires, probably more pronounced now because
A. You just had them rotated and your ear is naturally going to listen for any little sound or vibration coming from them. This happens to me after I get my tires rotated.
B. Your treads are breaking in to the new rotation. Not sure how scientific this answer is but I have to imagine after them spinning in one direction for so long they wear into that groove then when you rotated you might have to re-break them in.

I think your fine. If you had vibrations that would be cause for concern but since you don't then I think your good to go.

This is why you rotate tires. The front tires carry much more weight and also have more edge wear for rolling over slightly while turning. The backs tend to wear a little more in the middle because of the lighter weight on them. Tires also tend to feather the tread in the direction of rotation.

So now you have mixed all of this around with the rotation. They will make a different noise til the new wear patterns are established on the tread.

Check the air pressure and drive it for a couple hundred miles and I bet you won't hear any more noise.

I'm also guessing tire noise due to rotating fresh tires to the front
