I would like to put an original WTGT back on my original YH spare wheel for show purposes only!  Please describe how to locate and decode the original date of a Wide Tread GT.  Please post a close up photo, if possible.  Is the date something the judges would count off for, if it were the wrong date for the car?  Is a repop for a spare accepted just as much as an original?

Thanks,
Bryan

Wont be able to get to my laptop until tomorrow....however seems like we had this conservation last year around this time. I sent all 5 tires pics to Ed B (among other #s) for the data base. Really for this purpose.

Perhaps if he gets a chance he can post them ,I have no problem with that. If not, I'll re size them and get them posted tomorrow. If you do a little searching on this site Bryan, there is posts how to decipher ,going to see if I can't dig that up--steve.

Thanks Steve, Those charts help out a lot.  Would you please make the photo of the tire a little larger.  It would help me learn if I could compare the tire to the chart, and other tires.  Looks as if there will be a definite need for a pocket chart for the swap meets.  Thank you for your time and effort!

The more I look at the chart, the more confused it becomes. I have a G-Y Polyglass F70-14. The numbers go like this: MDLD  Y4A173 . I do believe it was an aftermarket replacement tire and not an OEM tire because it has "blem" stamped in the sidewall.  I also have an old BFG Tiger Paw and a couple of "stones" Super Sports I would like IDed as well if there is info.

Pre 70 OE's should be in the above 7 digit format.

Some good readings concerning these era tires on the Shelby forum ,search around a bit. I have not read in depth on the subject, just enough to decipher year and month for my tires, which I already knew were original to the car.

This being somewhat rare, I will in the near future post better images of all 5.

Per P.O.P and NCRS production date on my Z  was May 1, as I began documenting all my date codes I have been somewhat surprised how close to production the parts match eg; tires April, Engine 4/23   Rear end 4/24  Trans 3/21  etc...

At one time they built E250's and Thunderbirds in my home town (literally the buildings were sold for scrap price a few years ago ,sad) As a kid I would see rail cars and semi's of parts being delivered. Huge rows of stacked parts on pallets were in and outside the plant ( south side) at the end (north side) a constant flow of cars would cross over a bridge and be parked awaiting shipment near the lake. Really have to appreciate on a grand scale how production remained in sync....without cell phones and the internet. ( They also built ships ,cranes, electrical parts. Manufactured Steel and seamless pipe) Around 500 manufacturing jobs remain in a city of 68,000 now. Seamless pipe.
