the people that are saying they suck? did you actually try them? The places I ride at is extremely rocky and bumpy, I can see the 3.0 coming in handy bc you can run them at super low air pressure. I think the arrow srs is designed to run at 15-30 psi. If this took some of the sting out of small bumps I could see these being useful. Im ordering a pair, ill report after I give them a run.
I got a pair of Nokian Gazzolodi's. They had to be shaved a bit to fit my frame. I love them, I thought they would be overkill and sloppy but looked fun to try. I first tryed them in Plattykil Pa.
These tires are a different animal. First, you dont feel the weight much in fact it creates a gyro effect keeping your bike more stable in the air. I liked that since my bike tended to go left in the rear with other tires.
Secondly, they run at only 30 psi and the rubber is mad thick. It absorbs a lot of small bumps you would usually feel on the trails. Secondly it picks your bike up an inch, even if this tire flexed i cant see you getting a dinged rim or pinch flat the rubber is just too thick.
I ran them on azonic outlaw rims, which i think are really wide to begin with. I dont see this tire as sloppy at all.
you can get duro leopard 24x3.0 tires under the brand identiti (model contra) on chainreactioncycles or unicycle.com you can also get a Duro leopard 26x3.0 on unicycle.com. Arrow also makes them but they might be more expensive.
