2nd Gen Non-Engine/Transmission Spare Tire - 5 yr old - Put on the road??

[RBeard]

I recently put a 3 yr old spare on the ground and haul 3k in bed @ 80 psi regularly-no problem. check last 4 of DOT number near rim of tire for date of manf. (ex 2403=24th week of 03) to see build date of tire to find actual age.
