This probably doesn't apply to your issue - it is provided just as info on how to determine a tire's DOM:
Tire Age/Date of Manufacture
Unlike the other, more-prominent specs, the Department of Transportation's Tire Identification Number is of interest to tire owners and buyers alike — mainly because it includes the week and year of the tire's manufacture, and thus its age. Tire age, not just wear, has become a safety concern.
Found close to the rim, the TIN consists of a series of 10-12 letters and numbers that — like a vehicle identification number — are of little use to a consumer. But the last four numbers represent the birth week and year of any tire built since 2000.
DOT H25R YC24 4305
The tire above was manufactured in the 43rd week of 2005. Tires built before 2000 used a three-digit code, where the year was reduced to a single digit. If the tire above were from 1997 rather than 2005, its code would be 437. Would 437 also be the code for a tire made in the 43rd week of 1987? Unfortunately, yes, it would — and that's why four digits are now used.
Recently, the effect of tire age on safety has become a concern. Unfortunately, climates and how well a tire is cared for affect its aging, so there are no universal rules. Most tires wear out before age becomes an issue, but some automakers — mainly German ones — recommend replacement after six years in service, regardless of wear. Most automakers agree that 10 years is the maximum safe lifespan for any tire, including a spare that has never been used. When buying new tires, it's wise to check their birth date. Treat them like milk: Your family might finish a gallon before its expiration date, but then again, it might not. Why take the chance? For the same money, you should get the freshest milk — or tires — you can find. You might wear the tires out long before they're due for retirement, but why buy a set whose clock is already ticking?
