That is not the tire date code which will be a string of letters and numbers that begin with "DOT". The date code information is contained in the last four digits of this string. The four numbers of the date code are the week of the year in which the tire was produced and the last two digits of the year (for tires made since 2000). So a tire with a string of numbers that looked like this: DOT XDVFE 4507 would have been made in the 45th weeek of 2007.

I don't believe these are the date codes, at least not like mine. there should be 4 digits. the first 2 are the week they were built, the last 2 are the yr.
1407, this would mean these were built in the 2nd week of April 2007 jmho

Okay, I found them. 33 of 11 is when they were manufactured the date code is on the inside of the tires. Is this normal? At any rate I found them and once again thanks for everyone's help.

The DOT encoding can be on either side of the tire, or even both. There is no standard location except that is must be on the sidewall. By the way, most tires can be mounted with either side outwards, so "inside" and "outside' don't really have much meaning.
