How bad is it that our replacement tires are 15 months old?

Our 2018 CSS now has new tires; the old ones were 6 (yikes!) years old. I didn’t check the new ones’ date code until after they were installed. I’m disappointed that they are already 15 months old. 

How big a problem is this? We’re we robbed of 1/3 of the tires’ recommended life?

Warning, personal opinion follows .... It's somewhat unusual that tires sit for so long before being sold but if they were stored in a warehouse I wouldn't worry. There are many factors that determine the useful lifespan of a tire and recommendations to replace them after a certain time address the worst case scenarios like sitting for a long time in direct sunlight, running under inflated/overloaded at times, initial quality of the construction etc.. My beater truck has 10 year old Goodyear tires that show no signs of cracking, bulging or anything so I still run them. Just recently I had the first tire blowout ever in over 40 years of driving and that was not unexpected as the tire needed air added before the trip.

  Just my 68 year old opinion ; - depends how much you paid, -where they were stored before, and how high a quality they are.    Keep them covered and out of direct sunlight when the Tab is stored.  I try not to obsess too much over things like this, just enjoy.  Was not the best situation.
