i ordered a set of turf tamer tires and douglas .190 rims for my quad size 18x11x8 and i got them and the rim wouldn't go onto my quad they sent me the wrong bolt pattern then i noticed that alot of people run a ring on there rims how much more does this cost how much better is it and what kinda rims do i have to order i mean the specific thing so i don't have to redo my order a 3rd time. should i buy douglas or itp too i had douglas but i dunno who makes the ring ones better. any help would be appreciated.
