Thanks for the posts. The truck is a bi-weekly driver, used to move lumber, firewood, and other heavy items. I plan to keep it. The truck is so distinctive, I am unconcerned about the appearance of the tires and wheels.

Am a bit leery of modifying wheels, feeling that rebalancing would be impossible. Anyone got a line on some lug nuts to shim up the larger holes in 16" rims?

Thanks, all.
