Wheel capacity vs tire capacity

Most factory aluminum wheels are forged also, but finding a load rating stamped on them is rare. The majority of aftermarket wheels are cast (Alcoa are forged as noted above) and are more prone to failure. I've split 3 of the 4 wheels on my past pickup that were aftermarket cast between the lug holes and wheel centers. The centers of most aftermarket wheels have huge center holes and are lug centric versus hub centric like most factory wheels.
