Need Tire Balancing Expertise!!!
Got BFG AT KO 305/65/18 (33.7"/12.2"/18") road force matched, and balanced.
Now, the question is: does the amount of balancing weight needed on the outside of the two tires pictured indicate that they are defective? The one with the three weights all together took 5.5oz on the outside. The one with the three weights spaced out took a whopping 6.25oz on the outside! Once an old-time tire man told me that any tire that took more than 5oz on one side was a bad tire, period. What do you guys think?

Doesn't seem like they matched the high and low spots. I had mine done and told them to only use the stick on weights on the inside. I hope you dont throw a weight and hit the body of the truck.

I've seen bigger truck tires like this, especially more aggressive ones, take 5 and 6 oz of weight. Defective? Eh... In a perfect world I wouldn't like to see that much weight, but there is a reason they make 3 and 4 oz weights. If it was much more than you have I might worry. If it runs smooth, then I wouldn't worry about it.

I went through the same thing in october with my truck. I purchased new BFG ATs for my truck 315/75R16 from a very reputable dealer in my area and when I questioned the amount of weight he used to balance the tires he told me each tire with rim weighs aproximately 5o lbs. so adding 6 oz. to balance a tire and rim is not that bad. So far the truck rides smooth and the tires grip very well in snow.

Just my 2 cents... but I don't think they are defective so to speak but just the way BFG's are. I am not a BFG fan and that is one of the reasons. I have never had BFG's that I was truely happy with.

The amount of weight may not be an issue, but BFG's new bead protector design may give you hell trying to keep the balance weights ON the rims...
The last set of those I had, I could not keep outside balance weights on the trims to save the life of the truck... didn't matter what was done to keep the weights on the rims, by the time I'd made the 5 mile drive from the tire shop, most of the weights had been thrown.
(As a data point, even with tires that large, I'd be throwing FITS about that much weight. I would always tell the tire guys, "if it takes more than 4-5 ounces, it's not mounted right; break it down and try again." In most cases, that much weight means the bead didn't seat right. Break it down, and rotate the tire on the rim 90-180 degrees before re-seating the bead.)

Remember, it's not always just the tire that the weights are balancing but the rim too.
