just had a look at the sticker inside my door shut and its says v rated tyres up to 160 kph but should it be 91v or 94v as it does not state it anywhere on car or handbook and when search on tyre places with reg number it says 91 v but what is the correct tyre rating?
The important numbers are the 205 55 R16, the rest are just performance related and not really important for every day drainving imo. I have always used Michelin on my Focus and very happy with them - not the cheapest but good grip and long lasting,
I take it the r stands for radial which my rears are?
another thing to check is for bent pins in the diagnostic socket seen this on cars before? also you stated it has full service history if any of this was done in ford over the years this pcm problem would of come up before when they would of checked for software updates on service time?
