Im looking at buying some new wheels for my 06 6.0 f-250 The ones I have in mind are the 20" Moto metal 950's. My problem that I ran into today is that I have been emailling a few dealers on these rims, well one got back to me today and told me that those wheels have a negative offset and if I want to put these ones on I'd have to lift my truck 6". Is this true?? I want to keep my truck the stock height and I don't know what tire I should run with these new rims if they even work. I think my stock one right now is equivilant to a 35 or close to it. I heard that a 33x12.50 might fit. If you guys have any help to this subject it would be appreaciated. Thanks
