Dunlop SP StreetResponse 165/70 R18 Volkswagen 56 miles December 21, 2010
I have had REAL problems finding a suitable eco tyre for my Polo Blumotion (original model). The original Dunlop SP10s have ben discontinued, and the Streetresponse appears to be the replacement, but you CAN NOT get hold of them for love nor money. Its important to fit the correct type as the average mileage suffers hugely if a non-eco tyre is used. For example, at one point I was unable to find SP10s so was forced to put on a pair of standard Firestones, the average m.p.g. dropped from 72 to 58! Does anyone else have problems finding suitable tyres? Are there any other brands apart from SP10s (discontinued) or Streetresponce that are suitable?
