My tires are code 113, March 1993. The car was built in September.
Still has the original wheel weights and rides perfectly.
If I feel any vibration, it is corrected immediately.
None in 7500 miles.
I'll replace them when they are worn out, probably within the next year.
The same goes for the fan belts, and the timing belt.
I will probably do the timing belt and fan belts at 45k when the tires are worn enough to justify replacement.
My car is a unique situation, and I wouldn't dream or recommending the same thing to anyone.
Stored inside in a controlled environment makes all the difference in how a vehicle ages.
Most tire failures are due to underinflation.

gary
