Yes...this is another tire question...

Recently, when reading a thread on tires (age of tire before replacing), I read a comment from one individual in which he stated the 'clock' starts from the time the tire is installed rather than the time of manufacture. In most cases, such formula would not give the owner much additional time unless the date of manufacture was a year or longer before installed. Just wondering if anyone else agrees (or disagrees) with the writer regarding the 'clock' starting at time of installation. / Larry

2 years ago I took mine to a regional tire place that dealt with jumbo truck tires to get the tires I had on the coach at the time spin balanced.

As I stood in the warehouse I happened to look down at a stack of 4 LARGE truck tires....sized for 24.5 rims. ( I mean real jumbos). What made me notice them was the huge cracks in the sidewalls of all I could see and these tires were brand new ( never had been installed)
That sure tells me the "decay" of rubber tires must start about the time they leave the mold...let alonE hit the road.!
