tyre code

[Guest]

can anyone tell me where to look for date code for tire age the tire is a Metzeler and I've looked all around and can't see anything am i been stupid, and if i find date code how do i read them thanks

[Rijko]

Should be a 3 or 4 digit code on the tire.

well ive looked all over and found the little oval on the tire and it has bkf 454 anybody make any sense of that

Try google. There are countless links on how to read tire date codes.

My guess is 45th week of 2004. Time for a new tire.

A date code with only 3 figures applies prior to the year 2000. So "454" was 45th week of 1984 or 1994.

After the year 2000 the date codes had 4 figures.

well ive decided both tyres are shot im not going to take risks with tyres off unknown age so at the moment it has a Metzeler 130/70 /17 / 62h on the back but it looks a bit big to me it seems to hang over the rim what size are other people running its a 1980 gs 850. now on the front there is a Pirelli 90/90/s19 52s again this seems tight on the front mudguard any help would be good and finally is it ok to run different makes back and front thanks again

On my 1981 GS850 I have a 130/90-17 on the rear and 100/90-19 on the front.

I personally prefer to have the same make back and front, but have seen other bikes with different makes back and front.

I'm running the same sizes as 2BRacing. Think you'll find that is the closest or best compromise to the tyres originally fitted and most here seem to run with that.
Been running Continental TKV 11 and 12 front and back. Recently put on a ContiGo at the back. No complaints.
