Been checking out various sorts and types and more importantly..........price.
From re-centred H1 wheels to stazworks double beadlocks to staun..... who seem to have a bad rep for some reason.... reliability and very expensive.....
Two companies that tick the boxes.....Allied beadlocks for a black single lock steelie for $200 and
these babies that are an alternative to Staun and also come in the elusive 16.5 size which is important if you look at Super Swamper sizes less so if you look at Maxxis sizes that are 16 and 17 in the larger sizes......
