Dumb tyre question

[adam_rbts]

Anyone know what the difference is between a Bridgestone "S02" tyre and a "S02 N3"...? I've seen the latter available but Im a bit thrown by the "N3" bit as mine doesnt have it..

cheers

Guess I should have done a google search before posting eh..? Looks like it's some kind of Porsche compound rating.. ah well..

carry on people, nothing to see here..
