You can know the manufacturing date of a tyre through the DOT number printed on the sidewall of the tyre. The last four digits of the DOT tells us about the date of manufacturing. For example, let's assume that the last four digits of DOT printed on your tyre sidewall are- 4512
45 12 means the tyre was made in the 45th week of 2012. Similarly, if the last four digits were 4906 , it means tyre was made in the 49th week of 2006.

What is manufactured date of Yokohama Tyre for Ritz zxi
Yokohama is manufacturing tyres everyday and has been doing it since ages. The way to know the age of a particular tyre is through its DOT number which is stamped on the sidewall of every tyre.
Check the DOT number on the tyre..consider the last for digits..out of those 4 digits, the first 2 represent the week and last 2 represent year...for example- if the last 4 digits of DOT are 2413...here 24 means the tyre was made on the 24th week and 13 means year 2013...so, the tyre was made on 24th week of year 2013.
Do not use the tyre if it is older than 5 years as it could be very dangerous.
