Hi I have a 57 6100 and I`m looking for new tires but I have the stock rims and I`m finding out that most people wont change the big rims with the rings around them.Is this rim type hazardous to people going down the road? Is there any type of truck that will match my current rims? My truck has 6 lugs in the front & back? OR where can I buy new rims at?
