2014 GMC Sierra 3500 wheels cracked

I have had 3 wheels aluminum crack by valve stem but gmc tells me no one else has had that problem!! Has anyone else ever had this problem?

Sometimes a wheel can be damaged by improper lug nut tightening when the wheel is installed on the truck. Try to find a shop that will install wheels using a manual torque wrench, hand tightening the lug nuts in 3 rounds following the recommended sequence, rather than a torque stick or impact wrench.

I don’t see any TSB’s directly related to cracks by the valve stems, however these bulletins might be of interest.

It’s not over tightening of the lug nuts.

The valve stems are nowhere near the lug nuts.

What size wheels?


Is the crack in the alloy itself?
