I thought for sure with all the race tracks around here someone would have offered that service. Guess it's deal with it or sink the money into a new set :(Re: Anyone running BFG All Terrain KO2's on their truck?What kind of shop does "truing" ? Any chain places or is it going to be local mom and pop shops?Re: Anyone running BFG All Terrain KO2's on their truck?Truck only has 45k on it, so i would hope the shocks aren't already shot. I thought the exact same thing about some sort of "shave" technique. I know alot of guys used to do it for offroading for better traction before all the fancy tires came around.Re: Anyone running BFG All Terrain KO2's on their truck? CapriRacer wrote: Guys, The term *cupping* is widely used - and misused. Technically, the cause is out of balance or a bad shock - BUT - it has been used so often to refer to other forms of irregular wear, that the term is used interchangeably for diagnonal wear, one sided wear, feathering, etc. Besides, it's kind of hard to distinguish between the various types of irregular wear. Since most people are amatuers when it comes to identifying irregular tire wear - including many who work at tire shops - I think we need to cut these people some slack about what words they use. So what's your recommendation based on everything i've posted?Re: Anyone running BFG All Terrain KO2's on their truck? Harold Fairbanks II wrote: However, in my experience (and what worked to correct my ATs) the quickest way to correct the cupping is to swap them in an X-pattern so that each tire not only changes from front to back but also changes rotation. This, combined with running 42psi in all 4 tires, corrected mine in under 1000 miles. This is exactly what they did, only difference is they set it to 45psi. Yes, they are as loud if not slightly louder.Re: Anyone running BFG All Terrain KO2's on their truck? Harold Fairbanks II wrote: Rotating them will DEFINITELY correct the cupping. Also, running too much PSI will absolutely cause cupping, as will worn-out shocks. However...it IS reversible, especially on these tires. They will correct themselves quickly. Don't let the tire shop rip you off by telling you it isn't correctable. I've fixed cupping on these exact tires that was caused by my error (not rotating them frequently enough and running them too hard on my TOAD for less rolling resistance). After about 1000 miles, the cupping was gone. So the truck has 45k on it and i've only had it a few months. They cross rotated them and re-balanced them. They don't do alignments so he said i should take it somewhere to have that done. Since it's on all 4 tires, how will it correct itself?? I asked if flipping the tire on the rim so that it's putting the cupped edge on the outside of the truck would "balance" them out and he said no. So i'm all ears on how i can fix them!Re: Anyone running BFG All Terrain KO2's on their truck?Well i made it in to my local Discount Tire last night. Sure enough, all 4 tires have cupping on the innermost set of lugs. It's crazy, exactly every other lug on each tire is worn down. That's why when i'm going slow it sounds like tractor tires going down a road and then when i get up to speed it goes to that higher pitch. So i need to confirm that there's nothing i can do to fix the cupping before i dump a grand or more on new rubbers :( Re: Anyone running BFG All Terrain KO2's on their truck? dodge guy wrote: If they are that loud then they are probably cupped. If that's the case you will need to check the shocks and alignment. then put the choppy ones in the rear so they can even back out. I had a set on my Excursion and they were never loud. I need to look at my oil change paperwork....i think they had a note on there about something in regards to cupping....i'll need to re-read it and see what it said.Re: Anyone running BFG All Terrain KO2's on their truck? Harold Fairbanks II wrote: Yes, loud as hell. ...they howl like a pissed off ghost being given the business with a hot poker. That's a great way to describe it!!Re: Anyone running BFG All Terrain KO2's on their truck?When not towing i run them around 45psi. I've tried dropping down to 35psi and it's not better/worse. When hauling i raise the rears up to 65psi. I used to run BFG AT's and MT's on my Jeeps when i was younger and just never seemed to have this issue. As for the "look"...i could care less. Even though i'm only 37 i'm becoming an old man and preferring comfort and longevity over looks! When i go on Tire Rack and look up my size, this is the only E rated tire available.
