Gabriel - you're hard work! reminds me of the 5 'P's' ...
In addition to the info I have already given you in your previous 'help' post
I have telephoned MEFO in Germany for you but they only have the REAR Super Explorer and no fronts until mid May- ( 140/80/18 and 90/90/21)
Telephone +49 (0) 97 23 - 91 91 - 0
+49 (0) 97 23 - 91 91 - 19
but they do not sell direct to individuals- you would have to go through a dealership.
probably can get that rear for you-
Germany's biggest tyre dealership is DELTICOM
who might be able to help you
If you go to Delticom dealer page, there are tyre dealerships by country here
I have also telephoned Pneus-online
in France but they have no Mefo super explorers- They may have alternatives-
I did not ask as it seems you are solely focussed on those Mefos- I understand your desire but it may be worth considering alternatives Gabriel...
That you consider the MITAS ME 07
I get mine in a different size from Bob at C Wylde & Sons Ltd 0044-113 246 8888
(speak to Adrian) in the UK -
He might be able to help you ( he does NOT do Mefo or Mitas) 0044 208 6903366 he can get most tyres but you will have to arrange DHL or the like for pick up.
If I can be forgiven for saying this- you're better off to buy in UK & to carry hard to find items like specific tyres, sprockets, DID 520 chains, filters etc as they are rare as hen's teeth and chances of getting them always very time consuming and expensive and always seem to be DHL'ed from home in the end-
