i use to run some 35/16 boggers on my 80 and they were wicked.. but one thing i dont like.. as soon as they started diggin up any kinda hard clay or dirt they wouldnt do much but dig. so id cut them a bit if u were to get them.. the irocks or w.e are wicked all round tire.. summer winter mud snow or rock. a bud use to have a set of 39's on his 1 ton chev. it would go anywhere.   

good to see somone else from canada on here..
