I am on the look out for some affordable large mudders for my truck,I am finding every thing but 16 in tires that will fit my stock rims so I am thinking about modifying or customizing some wheels for my truck my questions are,will 15in wheels fit over my brake drums?can I take some 6 lug chevy wheels and redrill my bolt patern in them?my other idea is to cut the centers out of my stock wheels and weld them into some 16.5 rims?thanks Matt G
