Especially with ST tires, you MUST check the manufacture date on the sidewall BEFORE you have the tire shop mount them. They are normally stocked by most tire stores, but have an exremely low turnover rate.
Your "new" tires could be 2-3 YEARS old up in the hot loft before they get rolled down to be installed. They may look great, but the abuse and long storage will show up sooner or later.
The 4 numbers in the mold reflect the week and year of manufacture.
This Marathon ST radial was made in the 25th week of 2010 (2510)
