IF those digits are "508", then the tire was made during the 50th week of 2008. I think that means December 08......

According to the Michelin RV Tire Guide I have open in front of me:

Quote:
Prior to the year 2000, DOT numbers had only one digit to indicate the year of production. A Tire produced in the 1900's decade would have three numbers and a triangle symbol (<). The first two digits would indicate the week of the year that the tire was produced, the last digit would be the last digit of the manufacture and the (<) indicated the 90's decade.
That would say the tire was made in the 50th week of 1998. But I don't see the < designation either.
After the year 2000 all tires use a four digit designation

Not all companies have the 4 digits. I researched my Goodyears and they have 3 digits and were made on the 38th week of 2009. I can guarantee you that my tires are not 12 years old. I even spoke with the shop that put them on (previous owner).

Good Luck
Arnold

Dude... I think 508 means the 5th week in 2008

(0508 They leave off the leading zero so it shows up as 508)

1508 would be the 15th week in 2008
5008 would be the 50th week in 2008

Here's an added tidbit.. If you buy a tire or set of tires, check the date code.

If the tires are already 1-2 years old, or more, ask for additional discount since RV tire life is based on years of service life along with mileage.

Example: if the life of the tire (manufacture designated) is 5-8 years and the tire(s) are already 2 years old, that's 25% of tire's life already gone.

So you should negotiate additional discount since the tire life is already 25% used up.

5008 would be the 50th week in 2008..........
Sorry to add more confusion, but here is a copy & paste directly from the Michelin Service bulletin found on their RV tire site:

""The date when a tire was manufactured is located on the sidewall of each tire. Consumers should locate the Department of Transportation or DOT code on the tire that begins with DOT and ends with the week and year of manufacture. For example, a DOT code ending with 0304 indicates a tire made in the 3rd week (Jan) of 2004.""

So, Apparently they don't "leave off the leading zero".

Regardless, the above quoted info also means MY original answer is apparently incorrect.

Perhaps the OP picture is actually of a tire from the 50th week of 1998????? Hopefully the OP will help us by providing some additional info

Here! Determine for yourself.

Tire Date

Your tire was 50th week of the 8th year of the decade. Hopefully 1998.

And, FYI, all the D.O.T Plant Codes

Mr D is correct.

DOT regulations changed for tires manufactured after 2000. They switched to a 4-digit code which represents week number and year number (first 2 digits are week, and second 2 are year number).

If it only has 3 digits, the tires were manufactured before 2000.

If I'm reading this right, your tires were manufactured in week 50 year 1998.

I was thinking the same-----the actual DOT is the next number in line perhaps?
