I was at a bmw dealer yesterday just hanging out and this dude just fitted bridgstone tyres. Points: They made him late or he was late allready for an appointment They did not warn him about the tyres - to go easy on them He made a slippery pull off and drew a 3 - 5 meter black line He fell off. He damaged his bike on the Tar. I did not see this most unfortunate incident, but goes to show new tyres are really slippery at first. One should expect every one to know this. But hey we human and need our fellow riders and dealers to remind us all the time. I put my 1st set of knobbles on last week in the downpour of rain. I was extremely carefull, but still they were slippery. Little skidding every where.
