Michelin PS2 production dates 14 & 18 months ago???

[bowtiguy]

I just ordered a "new" set of PS2's to mount on my factory ZR1 spec A-molds as drivers from Tire rack as I'm saving the period correct gatorbacks/wheels off my recently purchased 91' Z w/ 9,600 miles. I realize ANYTHING is better than the 18 year old gatorbacks....

But, the build dates on these tires are 08/17 for the 275/40/17 fronts and 36/17 for the 335/35/17 rears.

I called tire rack on it and they stated those dates were the last production date for the PS2's in that size and no newer build dates existed in their system?

I know they aren't race tires ......Thoughts on mounting these year and 1/2 old rears and 14 month old fronts??
