The 1A does look like that is the plant code for the Taiwan plant mentioned in the other thread. BUT!! All Chinese plants are not the same from what I've been able to ascertain, and....I believe Maxxis comes from Taiwan and that's not a bad thing. Here's a little blurb from tireindustry.org if you haven't read it:

The three letters, “DOT,” indicate that the tire has passed all of the tests required by the Department of Transportation (DOT) for motor vehicle safety standards.
After the DOT insignia is your tire’s identification number (TIN). The first grouping of two to three letters or numbers represents the assigned identification mark for the manufacturer.
The second group can be no more than two symbols and identifies the tire size. The third grouping can be no more than four symbols and may be used at the option of the manufacturer to indicate the tire type or other significant characteristics of the tire. The final four numbers in the TIN represent date of manufacturer. The first two numbers reflect the week and the last two indicate the year. So a tire stamped 2910 was manufactured in the 29th week of 2010.
UTQG Code
The Uniform Tire Quality Grading (UTQG) was established by the National Highway Traffic Safety Administration (NHTSA) to test tires following government prescribed test methods and then grade each tire on three main components:
Treadwear: Treadwear is a comparative figure that attempts to project the longevity of the tire in the form of a three-digit number. This is the wear rate of the tire, comparable only to other tires within a tire manufacturer’s line. It is based on a control tire that is tested under controlled conditions at a specified government test track. The control tire is rated 100. Therefore a tire with 200 would theoretically wear twice as long on the government’s course compared to a tire with 100. Likewise, a tire rated 60 would be projected to wear about 60% as well as the control tire rated 100. Since it is does not take application, driving style or tire maintenance into account, the Treadwear rating cannot project the actual tread mileage of a tire nor can it be accurately used to compare the projected tread life of one brand against another.

Traction: Traction grades are AA, A, B and C (with AA being the highest grade). They represent the tire’s ability to stop straight in a straight line on wet pavement. Any tire rated under C is considered unacceptable for road travel.

Temperature: The Temperature grade indicates the resistance to heat and the ratings range from A to C with A being the most resistant to heat.

Thank you,, still can't figure out the year

There wasn't another oval past the first 2 with some numbers in it (4)? If not, would it possibly be on the other side?
