So how do I tell by the code where they are made?
Figured I'd give an update, these came in today and I don't believe they have ever been mounted or painted... the rims were bare steel and I still expect that they got a dose of saline. Not a spot on the outside of the rim is not rusted... if they had just gotten rained on then then mostly only one side would be rusted. Plus inside the tire and under the valve stem cap is spotless. Took me about 20 minutes to unmount two of them which is all I need right now.
Now that you can see them in person, I'm glad they're what you're looking for.
As far as tire codes go, on DOT approved car and truck tires there is a 10 digit (I think) alphanumeric code on one side of the tire. The first two digits represent the manufacturer and factory and the last four digits are the week of the year and year the tire was made.
I was just looking at some new Chinese tractor tires I bought recently and all they had was the date code and "made in China" molded in with no factory code. I also just got some Carlisle All-Trails and they have C43212 on the side so I'm assuming Carlisle uses a factory code followed by a date code. I'm waiting for a return email from them for confirmation. This website http://www.harriger.com/tires.htm
has the tire factory codes. C4 shows as a Dico plant in Clinton, TN which I believe Carlisle acquired from Titan Tire. It's shown on Carlisle's website. The 3212 number represents that the tires were made during the 32nd week of 2012.
I'll also mention http://www.barrystiretech.com
for everything you always wanted to know about tires.
