*** 1985 Honda ATC250R rear tire question ***

[bkvette3]

Good day, all.

Rear tires on my '85 250R - Dunlop KT557A - have X324 on one & X254 on the other - I am guessing date codes (???). How is this deciphered??? Thanks in advance. BK3

Look at last 3 or 4 digits. The first 1 or 2 are week tires were made last 2 numbers are the year. Example 2585 that means tires were made on 25th week of 1985 here's another one 0485 that is 4th week of 1985

Thanks for the reply back - much appreciated.

am I correct in assuming that mine would read 32nd week of 1984 and 25th week of 1984??? The first digit is a "X". Build date is 09/1984 on the build tag on the frame.

Was it common to have a "X" as the first digit for date codes on some Dunlop KT577A tires???
