Just a quick update for you boys...

After about 15k miles, I had my truck in at the deal for a service. I asked them to balance the tires for me. They said they couldn't, as there was too much road force variation... that it was a defect in the tire. They also told me that even if they could balance them, they were badly cupped, so they would still shake.

I haven't picked the truck up yet, so I haven't spoken with them in person to find out more. But that's where things stand right now. The balancing isn't a big deal because of the weight of the tire, but the cupping is disappointing.

 

cupping is more than likely from a worn suspension or being out of alignment...

when was the last time the alignment was checked and the tires were rotated? if you cross-rotate them so all 4 will be in reverse rotation when compared to before, then the cupping will fix itself in a few thousand miles. after that, you need to know what's wrong and get it fixed.

 

I rotate them every oil change - so every 3k miles. I don't cross-roatate them, so I'll do that this week and see what happens. I have my alignment checked every 10k miles or so, assuming it's not clearly out of whack.

 

I rotate mine every three months, no cross rotation... I've got 18000 on mone, and I love them to death.... I will continue to buy these tires until I go with a bigger size (33x1250s are the biggest size they offer)

 

My last set of MTs were the Destinations, they cupped also, I cross rotated them and it fixed them but MY GOD did it make them howl! Great tires though
