I have a recalled snow thrower md# 31a3bad 729. I called MTD on 2/16/10 to ask about the recall. They told me if I get a flat tire, don't inflate it but call them and they will send me a new rim for it. I asked why not send one now because my tires have been inflated many times before in the past and one tire lost its seal (flat tire) and I took it to a auto repair shop to get fixed.
