i have a bike like this, mine is all italian, ofmega and modolo mostly. The tires look like Vittoria Zaffiro. I put some of those on a bike and had one heck of a time getting them on and like T-Mar said likely pinched the tube. I had lots of slow leaks and flats until i figured it out and took a lot more care and time installing the tires. The wheels on this one are FIR.
