Tire noise

My 2014 Four Winds 28 Z with 3000 miles has excessive tire noise--since new. The noise comes on around 45 MPH and remains, although decreasing, through 65 MPH. The noise is accompanied by a chassis low frequency vibration but nothing through the steering wheel. At these low miles the front tires feel a little "cupped" when running a hand over them. I'm running Michellin tires, the same as I had on a previous class c with no noise/issues. Ideas are welcome.

You may want to check around. Michelin had a tire recall and if I remember correctly there were quite a few 2014 class c coaches that were involved.

Info from Michelin is here:

Believe the Michelin tire recall was with 2012 dated tires. Cupping would seem to be from a bouncing action- tire balance or possibly bad/defective shock(s).

There was a second recall about LTX M/S tires produced up until June 2013 as well. You would have to verify DOT numbers and dates as well as size.

I have had the fronts rebalanced and crossed. I'll watch for future misalignment signs but I think that's not it. Thanks

Thanks, Dave. I did check that but Michelin's recall was prior to my tires birthdate. Good call nonetheless.
