I had 4 bfg km2's on m truck and one blew out, I can get a Mickey Thompson baja atz basically brand new. If I kept the 3 bfg's on my truck and threw on the mt, would it throw anything off? Or be bad for it at all? The mt sits about 1/2 higher than the rest of the tires

 

It will mess things up if it's a bigger tire and you're running in 4wd

 

So if I'm in 2wd and have one bfg And one Mickey Thompson in the back will that mess it up? Should I put the two different tires up front and not run 4wd?

 

If the axle theyre on is driving it'll mess it up because it takes one tire longer to go around than the other. It will wear the tires and suspension out. And I think it will mess up your steering as well.
