Called my dealer for a price quote on stocker BT56's. He gave me a pretty high price for the tire and a decent price on mnt & bal. I asked him if the M&B price would hold for any tire I brought in. He said it would, but...."the tires you buy online are generally old and starting to dry rot." Implying that the tires he sold are better. Is he blowing smoke up my @$$ to scare me into buying his tire, or are the internet tires really past their shelf life?
