Coming back to the legal issue n older tires.....the owner's manual for my Alltrack states that tires older than six years are not safe and should not be used. Now we can argue about that all we want but in a courtroom, a lawyer will pull that out, ask if you read the owner's manual and ask why you disregarded published safety information. This, to an ignorant jury, is the kind of thing that leads to guilty verdicts in laibility cases and results in huge monetary awards if someone was injured or killed. In the end, it is FAR CHEAPER to buy a new tire or two.
