mc2ning FZ6

I was wondering if you guys know how much do the FZ6's weight and where to get them @ a good price coz what I found $2595 which I think is a bit too much, If I would get them for the same price shipped to Dubai I wouldn't mined but shipping would be expensive for them coz of the weight & size. I also wanted to ask if it was possible that the place where I'm going to buy them from to change the tyers on them from 245/45/20 to 255/45/20 and keep the same price.
