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.
I write a blog on RV tire application and safety. RVTireSafety.com
Also give seminars on tires at RV events across the US. 40 years experience as tire design & quality engineer for major tire mfg. Freelander 23QB on Chevy chassis is my RV
