Ordered the Delta Cruisers from Bike wagon. they came today and fit tight thanks 3-speeder and SirMike---samI like the Schwalbe Delta Cruisers. I've used a few pair of these ones with K-guard:

Bike wagon has treated me well when ordering from them. Just know that these tires have a larger girth and may need a slightly greater clearance. On my Raleighs I've had to spread out the front of the fender a bit to accommodate these tires. I really like them though.
