are there any downfalls to using wheel adapters on our trucks? reason i ask is that i got a a set of rims and tires for free from my cousin but they are 6 lug. i tow my boat with the truck and occasionaly load it up pretty good. would there be an issue? obviously i would be better off getting rims that have the same pattern but ill never find a set of rims for the same price that i can buy wheel adapters for.
