BFG KO2's Balancing Issue

I too am having balancing issues with the 265 C loads. I had them order a set of 275 E's as well but went with the 265s for mileage, ride quality, and accel/braking. I havent run the 275s so I really just went off the info I could find on the forum. I am considering taking the C's back for the 275 E's - whats your opinion on the 275? it seems you really like them, and maybe I have nothing to worry about. All things aside I would like the slightly larger tire.

Have the same tires, stock sized C rated, same issue you mention there.
Got them re-balanced and alignment after that. Steering wheel never really got back to zero vibration so I just got used to it. Think of it as a free hand massage...
However, I did notice that once the tires warm up the vibration seems to decrease quite a bit.

Most of the time I wish I had 265 C tires. I just got the 275 because that was the only size in 17 when they first came out. I like the 275 but I would most likely be better of with a lighter tire. I do like the extra toughness of the E tire in the desert rocks but the C would have been fine. I ran 265 C bfg ko tires on my previous 4runner with no problems but they did need balanced now and then. I just had my 275 KO2 tires rebalanced since I had the lifetime balance. I was getting a slight bounce at 80 mph and it seems fine now after the rebalance.
Thank you, thats very helpful. I like the look of the 275 but for my application the 265 is more than enough. Now if I just could them to balance haha!

I would not do load range E.... That's a 10 ply tire and I'm not sure you would ever load your 4Runner down enough to justify having them.... I think they are also going to ride a bit rougher.
Now for the balancing issues!...
It seems a lot of people working at all different tire companies either don't know or don't care enough to do it correctly... So that being said, when you buy a new tire, there is a little yellow or possibly red dot a little smaller than a dime on the sidewalk down by the bead. Not on the bead, but real close to the bead... I'm sure most people have seen it. Well that dot is put there by the manufacturer. It tells the installer that if they line the dot up with the valve stem that the tire will balance much easier and usually requires much less weight to balance the tire.... It works, I've don't it myself way back when I was an auto mechanic.
Now if a tire is taking quite a bit of weight to balance, and I'm talking about regular tires here not 37"+ monster truck tires.... So like more than 3oz.... Pull the weights off, break down both beads, spin the tire 180degrees on the rim and that should make it use less weights to balance....
Now... Are you 100% sure that your rim is not bent even a little? If it was and you didn't know that would allow you to get really close and the mech might even get the machine to read zero after adding weights ... But it will still have a little vibration when driving.... I know this from when I had my last Jeep Wrangler... I had purchased some KO2's and had what sounded to be the same issue.... Ended up having then pull the tires off the rims, put the rims on the balancer and checked the runout on them... They were bent... I could see it once the tire was off,... Didn't even need a dial indicator.
I hope this has helped!

I'm about ready to get new tires. I have KO2s in 265 C rated on TRDPro wheels and they never stay in balance. Had them balanced twice at tire dealer always for them to go out of spec and start shaking within 100 miles.
I took them to a local Toyota dealer today and had them road force balanced on the Hunter and it was good for a quick trip on the highway with the technician for a few miles so I drove off happy.
This afternoon, I'm getting bounce again on the highway.
I'm about ready to ditch these tires and try another brand. I never had this problem with the original KOs.
I also might try going back to some stock Trail Rims.

Got brand new KO2's installed on TRD pro rims today at America's Tire. Funny that one wheel has ~3oz, another has no weights, one has like 3/4oz and the other has ~2oz. Road great on the way home, hopefully it stays like that. I got a little worried seeing ~3oz on on wheel but from what I read online I think that's fairly normal.

275 ''E'' and Mamba M-14 rim and I marvel at how it is dead smooth and straight up to 85 it is. Smoothest KO's I have had in 40 years of buying them.http://www.toyota-4runner.org/attachment.php?attachmentid=275416&stc=1&d=1511051712

I was about to suggest this... I have had so many issues with balancing my KO2's and finally did the RoadForce balancing -- and like you said, smooooth as butta!

What is RoadForce balancing?I was about to suggest this... I have had so many issues with balancing my KO2's and finally did the RoadForce balancing -- and like you said, smooooth as butta!
THIS right here is the answer. It is called match mounting. The red dot or yellow circle is the lightest point of the tire, and should be matched with the valve stem. I had the same vibrations with Toyo Open Country AT2 and for the longest time, counldn't figure it out. I contacted Toyo about the issue and they told me that the tires need to be match mounted. No more vibrations!
As for Hunter RoadForce, its THE ONLY WAY you should have your tires balanced. ALWAYS ask your dealer if they have a Hunter RoadForce machine because they can balance the wheel/tire at speed.
