Does anyone have Silverbacks on there quad's? They look like an awesome tire for mud ect., but how do they ride on trail, rocks and roots? They look like they would ride rough, do they?
The 30" with 2" deep lugs would be fun in the mud! Would they work in the snow? Post up some pic's of yours if you have them!

 

I had 29.5" Highlifter Outlaws which are pretty similar. They had 3" lugs and rode pretty decent on the trails and performed great in the mud/snow! My best advice is take your time acclimating to how your machine handles with them before going WOT on the trails. You will get a lot muddier!!!!! I had a 6" lift with spacers in addition to the tires on my 05 800 and just putzing down a muddy trail would throw it everywhere!!!!!

 

Yes they are ROUGH at slow speeds..nature of the beast with those large lugs. Above about 10-12mph they smooth out pretty good.
