It's a 5212, maybe they're not making them anymore at that factory.

Season for long distance travel is over and these last 2 will be junked in the spring.

I suggest you pick a nice day to record each number. They may or may not all have same number as tires are made in batches of a hundred to 1,000. You may find some tires have the full serial (including the date code portion) on the inside so you might need a flash light or even have to move the RV to get the number fully visible.

Note there is no O or Q but do have the number zero. Also no i but do have the number 1
I assume this is the s/n you are referring to. Three were easy but the fourth was a b...h since it was on the inside and I had to snakecrawl underneath to get the pix.



I have the pix of all four numbers saved in a database I use for all the TT records.

the "full S/N" for your tire is all the letters and numbers right after the "DOT" and would end with the date code portion of 2715.

the 539303 is not part of the DOT S/N but is a tire company number.
The SN could be 8 to 13 characters long.
1st 2 are a code for actual producing plant and last 4 are date code. other characters are controlled by the tire company.

Interesting. Never seen a Q as I recall. But the characters that r most important are the 1st 2 (plant code)

1K in your case

and last 4 numbers which r the date code.
