I have a post in the greasy spoon about the reason for this post. I have 215/75/15, on the front and 235/75/15 on the rear. What would be a good size for the front and rear? I do not haul big loads it is more of a pleasure vehicle like most trucks are in this day and age. The reason for wanting the same tire size is that I have wheels with multi-lug patterns so if I get a flat they can be switched around. My spare wheel is not.
