We ran 4 on 4 everything for a long time. But needing beadlocks now presented a challenge. Had a huge amount of trouble finding 4 on 4 bead locks. So called EC and got some of their hubs (4 on 4 AND 4 x 110). Love them. now with a small amount of work, we can use what ever set of rims we need for that nite. Not saying that switching back and forth is the answer, just making use of ALL the rim and tire combinations we have. My 2 cents
