2nd time buying these tires. The first ones were for a long John Yuba Mundo Cargo bike. I bought the 2.4in. for front and back, love the extra cushioning in the ride and reasonable rolling resistance. They grip "all right" -- I'm not looking for speed anyway, as I'm heavy, the bike is heavy and I'm often tipping the scale as rider + bike + cargo at 375+lbs. I can't tell you how they handle faster than 20 mph. They were easy to fit onto the Yuba stock rims. The Mundo is my mini-van. Second time I have bought the tires I purchased the 2.2 inch Cargo 4ply tires for my Surly Troll that I often load up with Velocity cliff hanger 25mm rims on the Troll, the tires were a lot harder to fit on. But they're on and I've noted the tread wear between the Yuba after 350 miles, and the Troll's spanking new tires. "There's only a little wear from the 300 miles on the Yuba". I may get 1,500 miles on them easy! So, in short recommended!
