Avon compound markings

My brother has a Terrapin with Avon crossply slicks and I’ve been trying to find out which compound they are, probably A15/92 but I can’t see any such markings on them.

Can someone please help, we need to order some new tyres?

Also where is the best place to get them from, we live in Cumbria.

Thanks.

John.

There is a small box to the left of the size marking. in that box you will find a 4 or 5 digit number. They relate to the compound. If you make a note and speak to BMTR- Avons distributor- they will be able to tell you what compound they are.

Just had a quick look in the garage and on mine 14207 relates to A92 and 6476 relates to A15

Could be wrong but I think there's other info in that number so they vary across tyres... As said, take the number and phone BMTR... They can tell you what the compound is from the code (along with a lot of batch related stuff and the operator's inside leg measurement probably)... Always found them quick to come up with the compound over the phone

AFAIK.... BMTR are the only source of Avon slicks... Based in Brum but always found them sharp on the delivery time.

tyres

Funnily enough, I actually made a note of the markings on my tyres yesterday.
7.2/20-13 Code 6583
8.2/22-13 Code 14209
These were purchased as A 92 compound.

To my knowledge, the codes that you are all quoting are manufacturing batch numbers and you have to phone BMTR or Avon motorsport technical to ask the compound that was used for that particular batch. The number itself is not a compound code.

The Avon code defines the tyre size, construction and compound. You have to contact the supplier to find the compounds of the tyres you have, or post the numbers here and someone may know.

The numbers on mine are always consistent from set to set so , as mentioned, they prob are a combo of size, compound etc. Certainly a quick call to BMTR will reveal all.

I agree and the Letters in the box on the left hand side of the sizes indicate batch and date. Our fronts have FEHI and the rears have OFHI.
