Rocked up to my tyre place (who I know personally), cash in hand for some decent 17's for my NC. The guy says how heavy is your boat. 1700kg.

Put your wallet away mate was the reply. There was nothing I could get (for an NC) that would be legal. He said best case was that I would keep hassling him to have buckles taken out, worse case was that I would have an accident (related to wheels or not) and one look by the RTA and insurers and I would be out of pocket for my car (bad), boat (worse) and whatever I took out (there goes the house).

I have to stay with any factory wheels that were available with the heavy duty tow package, which is sadly very little for pre-au wheels.

AU and onward wheels might be a different story - might be made for heavier loads, but I would double check, and check any aftermarket stuff REALLY carefully. Might not cause an accident, but might be a convenient excuse to void any insurance claims (whether you have told the insurer about the 18's or not).

Someone I know from my boat forums had an accident towing with an ED. They were pedantic about their legality but the state transport authorities hauled their car and trailer over the coals looking for errors.

Towing heavy stuff is fine until it all goes wrong - then everyone is out to find something wrong with it it seems. I just had to spend $2500 bringing my trailer up to new safety specs.
