Been there...done that!!! Save yourself some leg work! I've already done it for you....check out the truckstops/"The Chrome Shop"....I beat the bushes trying to find anything decent that would fit a large diameter stock wheel, to no avail. They (it's a chain) have a good selection of covers of all types.
They aren't cheap, but who would put a cheap cover on a $200K truck? Hope this helps!
