11″ tire width on 6″ rim

Hey Guys,

I am about to pick up some 28" mud Mayhems for my 660. Just wondering if you think I would be alright to do 11" wide tires all around on my stock rims 12" rims (6" wide front, 7.5" wide back), or if I will likely have issues.

I was going to run 9" tires in the front but since the mud mayhems tend to dig, I figure wider is likely better for my riding style. Sftermarket rims are a bit pricy for me at the moment so I would like to use my aluminum stockers.

Thanks in advance,
