getting the tyres isn't the only issue, it's also the $1000's woth of nuts, bolts and washers........... as well as the manhours to assemble them.

strapping them together would only create further delays of the bundles separate ??

As far as I know, both H.D & Teretonga share the same 'bolt together' bundle technique. Costs a bit for the correct bolts & washers, but Tyres are free as are the P.D Guys to connect them together after they have been checked for consistency. These bundles work well when used in conjunction with sand traps & can be added too as new danger areas are identified & time permits.
