The sidewall seems pretty stiff, there were a few hard turns that i felt a touch of roll. They are heavy spec wise they say 20 a piece but i honestly noticed no difference on the weight. I still have my stock 23" ohtsu's up front and these are actually bigger they are 22.5". The nice thing if you step up the wheel size you shouldn't n otice any sidewall roll. I paid $115 and some change, America's tire Co. did a price match from these guys http://www.mud-throwers.com/inc/sdetail/12256 They have gone up $3 in just a few weeks. Hope this helps, I will post more as I ride them more but at this point I am very pleased. There is a hard to see horrible picture of them in my pics but you ca ntell they are taller then my 23's.
