i just have factory wheels with a cognito 3 inch lift in the front, but i do pull a goose neck with a small tractor & dozer and other landscaping stuff, the reason for the question is that i had a friend with a 05 powerstroke with some 22's and he pulled my little dozer while i pulled the tractor, and he bend a wheel in the process i dunno if it was the type of wheel or the weight of the dozer....and input will help out greatly!!-Thanks
