I wish you had left the photo up.

Around 2000 they changed from 3 digits to four.

IF you have the correct number. ( your photo didn’t show DOT?) then it would be the 26th week. But the year could be 1991 or 1981.

The code mandate came about in the early 70s????? Before that some manufactures dated their tires but I have no clue which ones did that.

Easier to tell the date with the newer 4 digit code.

But since it’s a Hornet the experts say “Age doesn’t matter”

YRMV……I know mine do.

the reading could be the same for 1981 or 1991 but when 1991 there should be small triangle near the number. to indicatie the next decennium

A 40-year-old tire can be in reasonable condition for a static display. Not for riding, under any conditions.

When I changed the 30-year-old K70 off of my new-to-me Firebird in 1999, I punched my thumb through the sidewall while I was peeling it off .... And it had been stored indoors most of that time ...

Static display is one thing. But I wish when folks talk about these worn out tires they mention that. Instead they make it seem like it’s fine to ride around on rotten tires????

You need to keep your audience in mind. We have VERY seasoned enthusiasts on here…….but we also have new comers that are reading this stuff.

1961 ,71 ,81 or 91

i think it could be a fom tire 61 or 71 ? ... any other markings on the tire ?

there were DOT changes mid 1971 ( other than the date stamp )

...and by 81 and 91 ... there would be more DOT information
on the sidewall , including the DOT stamp itself .

... but if its and off-road tire , ( or a gray market import ) it does not need to have anything DOT on it .

ah sorry, not all read Dutch. but in the same post:

"de banden zijn oud. ik haal er een datumcode "252" vanaf wat volgens de uitleg zou betekenen: "week 25 1982" want er staat geen driehoekje voor 1992 achter. Kan kloppen met de kilometers en bouwjaar. Er zijn nieuwe besteld want alhoewel profiel dik in orde is zijn ze volledig uitgedroogd. ('92 kan ook kloppen, iig zijn ze dan tenminste 29 jaar oud)"

new ones have been ordered because although the profile is still good, they are completely dried out

and some carburettor testing in this movie
I'm not so good with carbs and jets so always go to Startrick.

next visit to Startrick will be with the BSA A65, when I've done some more miles for running in.
