Avon tyre date code - Martin Prior - 12-10-2019
I've acquired an A7 wheel with what appears to be a perfect, zero-miles 3.50x19 sidecar tyre fitted.
BUT the only thing that I can find that looks anything like a date code (on a small, oval panel with "screw heads" moulded in) reads M033. I think that this means that it was manufactured in week 3 of 1983, in which case it's only fit for yard shunting.
Can anyone confirm this date?

Martin,
Don't know if it helps but the new ones I bought this year show M4918, which suggests week 49 in 2018. I'm stumped as to which year ending in 3 yours refer to as I also have some M1002's. I'm sure someone more knowledgeable will tell us.

As the 3 digit code was used until 2000, it could be 1993. Only digit for year and not one for the decade because tyres weren't expected to last for more than 10 years.
RE: Avon tyre date code - Martin Prior - 12-10-2019
If I've understood it correctly, three digits date from the 'eighties, three followed by a triangle are 'nineties and four digits are 2000 onwards.

From an American site but I assume the same in the UK but did Avon use a triangle?
This is where it gets confusing -- there’s no universal identifier that signifies which decade, so in this example the tire could have been manufactured in 1982 or 1992. Some tires do have a small triangle following the DOT code to indicate the 1990s.

Hi Martin, this link explains UK DOT markings completely and simply.

Crikey, would it have been too much trouble for a human to do the voice-over?
RE: Avon tyre date code - Martin Prior - 13-10-2019
Thanks, Ian. That was where I got my information from.
