i bought a new 3200 last july. i now have a problem with one of my rear tires. ever since the tire was new, there has been a small "chunk" of rubber sticking out from where the tire joins the bead. i finally tried to pull it out(i know,stupid). when i did i heard a minor air leak. now it keeps deflating. the dealer says it is not under warranty, i insisted that it should be and they are going to have their cub rep come out and look at it. i KNOW that the tire has not gotten against anything, and feel it is a defective tire. what do you all think?
