If I was selling privately I wouldn't put new tyres on a bike unless it was at the indicators. I feel it's unfair to expect dealers to have to put new tyres on a used bike. They should have taken tyre condition into account when pricing to buy and sell it. Yes it's a little squared off, but all tyres will get like that unless you don't ride motorway at distance or you have enough money to put new tires on every few thou.
Personally, I don't like seeing brand new tyres on a used bike. Makes me think it's just been put back on the road from track..................
