Hi All,
I have recently been chatting to a colleague of mine who has been in the tyre industry for some 20+ years including time with Formula 1 and it would appear that the N rating is not all its cracked up to be. Apparently to qualify for an N rating you must pass the following tests:
Wet Grip.(Including Braking)
Dry Grip. (Including Braking)
Mileage (Ability to do 6,000 miles)
Road Noise.
These tests are carried out in various countries in Europe and your required to pass all 4 to get an N rating. However some excellent tyres do not get the N rating due to purely failing on road noise, as this was the case with Yokohama in Switzerland as it would appear that some European countries like there tyres to be silent running. So in short why bother with the N rating? obviously you stick to the correct speed rating etc and brand name of tyre if you wish but you could get a better gripping tyre that is not N rated i.e Goodyear F1 or Toyo. Lets face it with the rumble of the flat 6 behind you at 70 MPH tyre road noise is insignificant[8D] after all Continental got an N rating and they are awful[
] strange that there German tho[8|]. We don't buy N rated oil or Petrol do we??? and if you have an accident does your insurance company refuse to pay out if your tyres are not N rated.....No is the answer.
So is the N rating all it's cracked up to be? or is it just a license to print money[8|]
Your Thoughts Pls
