|  Tire age 
			
			Can anyone help me determine the age of my tires?  They are bias ply redlines  DOT CYLD. F1K5227 I assume these are repos, just don't know how old and if I should trust driving on them. They appear to be in good shape. Thanks. Dan. |

			That is the old DOT numbering system.  Automatically, I would find different tires to drive on.

			As to longevity of tires I will say this.  The 68 Camaro I bought came with a stack of receipts.  It had Cooper Cobra purchased in 1989.  They were so old they didn't have the snake on them.  They were still going strong when I sold the car in 2015.  I also abused those tires with a 410 rear end every weekend.  Best tires I ever had AND they refused to shred its tread. One  caveat though.  The car was always garaged and out of the sunlight all those years. I will always buy Cooper Cobras!
