Have a look at the numbers at the sticker near the fuse-box near the drivers-doors or in your service booklet. You will find one number starting with e.g. 253 for a Kombi based vehicle, 255 for a Caravelle or Vanagon GL (see also production figures above and the dictionary at vanagon.com) The three digit number that follows tells you about the stock engine, body, tire & rim combination. The first two digits are quite complicated to structure, the last one tells you factory tires for your model were 185 R 14 tyres if ‘7’, 205 R 14 if ‘5’ and finally 195 R 16 if ‘A’. The optional 205 R 16 tires were encoded M 855
