The noise on ours became quite bad. New tyres and a wheel alignment have fixed it all up. If you catch it before it gets bad you may be OK with a tyre rotation and alignment, but once the tyres start to wear unevenly there's not much that will correct them.
Not a bad idea to get an alignment done regularly anyway, its fairly cheap.
