Not doubting that longlux knows what he is talking about, but some vehicles have passed engineering with them fitted - looks like you can only do it for older trucks though with a low speed rating.POS wrote:I think Lowlux knows a bit about tyresberetta wrote:Slight hijack, sorry, but can someone who knows confirm that Super Swampers (not boggers) are not a legal on road tyre?

They will suffer excessive wear have little stablity at speed and are not legal for road use as they are not speed or load rated and therefore do not meet A.S.
As for a hard core off road tyre they are one af the best., he has been working for australias two largest and best known tyre brands for as long as i can remember.
Oh, he has also probably seen more swampers than everyone else combined on this board.
He knows his stuff.
By the way, yes he is correct. They are not street legal.
However - arguments aside - using swampers on a DD rig would be a silly idea and a huge waste of money.

The engineer told us these vehicles can be driven on public roads anywhere in Aus. both trucks are placarded and approved on 36'' Q78 super swamper tyres which many people over here think are illegal . We downloaded all the Australian design rules off the net
The engineer had his copy, and we discussed and argued each modification until we were in agreement. Bill.

If you have a late model vehicle you are basically stuffed.

Neither vehicle originally had speed rated tyre placards. but new tyre placards covering the 36"Q78 swampers were provided by the engineer once we proved to him that they were DOT rated from Interco's techncal literature on their website.
There are some instances where an engineer has to call on his training and make qualified judgements and I suggested he do so on quite a few points of conjecture. He charged $1000 for one vehicle and $500 for the other and I made him earn every cent, but I am fully confident that everything is legal and that he didn't turn a blind eye to anything.
