After a long trip from TN to Wilson, NC Tom noticed one of his trailers had blistered. A fairly new tire.
Last night betwixt my various tasks at the airport I caught a break while waiting for a plane to arrive and saw a few clips on tire manufacture dates on 60 minutes (I think that was the show). Apparently the US is alone among nations with lots of vehicles by not having a *use by* date enforced on tires. The standard is about 6 or 7 years from manufacture and the tire is done, even if it has never left the sales rack! Tires age just sitting.
Not only should we check the manufacture date on our vehicle tires, but we should check the date code on our trailers. Anything over 6-7 years old and you may be looking at a tire that can self-destruct on the highway.
Date codes: Usually on what is the normal inside tire wall. Our US manufacturers don't make it easy. At the end of a string of DOT numbers there will be a code number. A 3 digit code is dangerous, means the tire was made in the '90s or even earlier. A 4 digit code sez the tire was made in the decade. First two digits are the week of the year (i.e. "24" is twenty-fourth week of the year. The last two digits are the (i.e. "06" would be 2006)
So check those tires! If you have a 3 digit code or a 4 digit code that ends in "00" or "01" or "02" think seriously about swapping them out for new ones. I have lost trailer tires and car tires at highway speeds and it wasn't much fun. Nationwide, tire failure at high speeds has caused many fatalities. Please take the time to check your tires, and remember, the best way to keep a good tire healthy is CHECK AIR PRESSURE!
