Yes, once and awhile tires/wheels can arrive not perfectly balanced for various reasons (although under 40MPH sounds odd). Just contact my customer service department at 1-800-428-8355, ext 386 for assistance. They'll likely direct you to a local installer (hopefully one with a Hunter Road Force machine to see exactly where the issue is, as wobble under 40MPH is odd) and have you fax an invoice over for reimbursement.
