An old friend sent me an ABC video about tires. I'll make it short but want to share the warning. Many "brand new never been used" tires that are sold by trusted retailers are, in fact, old and apt to have the tread separate from the tire resulting in injury or death. Tires should NOT be more than six years old...from date of manufacturer NOT date of purchase. On the outside of each tire you will find a series of letters and numbers. Sometimes this side of the tire is mounted with those number on the axle side not the outside. There are three rectangular boxes with clipped edges. The last box has four digits in it. The lst two digits represent the week that the tire was actually manufactured. The last two digits represent the year the tire was manufactured. So, for example, 4202 means your tire was made in the 42nd week of 2002. It is six years old even if you bought it last week. It is dangerous. I haven't checked mine yet but I'm going to do it tonight. We've just always "assumed" that if we buy new tires the kids are safe and so are we but a number of families have lost members because they did not know what to check either. DDD PS: I'm beginning to remind myself of "my Mother" who always had dire warnings that we all laughed about and forgot.
