That is only part of the DOT ID number........full ID number is 10 to 12 digits long.
The rest of number will be on other side of tire.
The last 4 digits of that ID number will be mfg. dates (since 2000)
OR the last 3 digits will be mfg date (prior to 2000)
Look for complete number on inside sidewall.
4 digit---first 2 are week, last 2 are year (3711---37th week of 2011)
3 digit---first 2 are week, last 1 is year (378---37th week of 1998)
