Trailer Tires and legals.

[bogged]

Can you legally use Boggers/Swampers (non legal tires for a truck) etc on a trailer ??

I know you cant on the truck itself, but just to answer an argument if its different rules for trailers.

Vicroads site is clear as shit.

[matthewK]

i know u can run ATs on it id think u could run Boggers/Swampers if its an Off Road trailer

[sudso]

Cant see why not. As long as they are load rated to the capacity of the trailer and are speed rated for highway use. But I'm talking SA here we just do what we bloody well like
Are boggers and swampers bias ply though. That would make them illegal if they were wouldn't it?

[bad_religion_au]

bias are only illegal if the axle on your 4by only came out with radials

so i got NFI whether boggers on trailers would or wouldn't be illegal.

yes boggers and swampers are bias

another question... do trailers have a maximum tire size? could you build a trailer on 44's if the mood took ya

I am going to work today (for a Police Funeral) so I will endeavour to check it out. Usually trailers tyres when checked for road worthiness are normally viewed for overall condition not type as boggers etc are rarely fitted. Good point.

In SA you can fit 2nd hand tyres to a newly manufactured trailer as long as the load rating matches the trailers GVM and are speed rated for highway AND they have legal tread.
I wouldnt use really old ones though as I had a blowout with one once. Damn tread and steel belts wrapped tight around the hub and axle

Question is Bogged, is it safe to put bias tyres on a trailer?
I would say yes, as many trailers have cross ply tyres on them and I am pretty sure its legal.

[CRUSHU]

You would have to check the trailer for a tyre placard. All trailers manufactured recently must have a tyre placard (part of the built plate) fitted.
That would not apply to home made or older trailers though, I guess.

The Vic Roads Vehicle Standard Bulletins VSB #1 refers to the building of small trailers. It is fairly lengthy, and it is a guide with the full specs being contained within ADR's, which I don't have a copy.

There is nothing specific in the guidelines that restrict the use of boggers on a trailer, but the overall restrictions are that they are roadworthy, and are speed and load related to the environment being considered.

Vic roads Vehicle Standard Information (VSI) No 9 Refers to the ATM (Aggregated Trailer Mass) and GTM (Gross Trailer Mass) when considering the load capacity of the tyres being fitted.


I would check the details out with a reputable trailer manufacturer to see what tyres they can fit to their products based on customer requests. Maybe one of theose outback trailer manufacturer would be a good start.

And before that I wrote

Looks like SA and Vic actually have something in common

[stool]

My boat trailer is running on 32''s rego as a home made

[blackmav]

Got my tooltrailer regoed wiyh 35's

[CRUSHU]

yes, but not with out speed rated tyres....

[sudso]

should be clearer than shit now for your arguement eh Bogged?

[bogged]

should be clearer than shit now for your arguement eh Bogged?

yea nicely cleared up

[bogged]

Any more ideas on this???

[Guy]

Do it.
Crash it.
Go to court.

Tell us...

Are interco tyres speed ratings recognised in this country ?
If so the answer would be yes you can run em.
If not, no you cant.

Any more ideas on this???

I cannot see the pic, what is it?

16. WHEELS AND TYRES
Wheels and tyres must be adequate for the loads they are to carry and the speeds at which they are to be towed. The GTM of a trailer must not exceed the sum of the load ratings of its tyres.

16.1 Tyre Placard
Trailers must have a tyre placard made of a durable material affixed to it in a prominent position showing:

for each axle or group of axles the tyre size designation and the rim profile as fitted;
the recommended cold inflation pressure( s) in kPa for tyres on each axle or axle group;

the load carrying capacity of each axle or axle group which must not be less than the portion of the ATM carried by it or the appropriate higher figure if the provisions of Section 15 for close coupled axle groups are applicable;

the statement: 'The sum of the load carrying capacities of the tyres fitted to any axle or axle group of the vehicle shall not be less than the relevant load shown above. ';


1 Tonne 3 Tonnes
4 Tonnes 4 Tonnes
2 Tonnes 2 Tonnes

Non-Load Sharing Load Sharing
· either the statement: 'The tyres fitted to this vehicle shall have a speed category not less than 'L' (120km/ h) '; or if the recommended maximum vehicle operating speed is less than 120km/ h 'The tyres fitted to this vehicle shall have a speed category at least equal to the recommended maximum vehicle operating speed '.... 'km/ h. ' where '.... ' is the vehicle manufacturer's recommended maximum vehicle operating speed.

The tyre shall not be referred to by name of manufacturer or brand name on the placard. The tyre placard may be affixed to or incorporated in the trailer plate referred to in Section 3.

16.2 Retreaded Tyres
If retreaded tyres are fitted to a trailer the tyres shall comply with the requirements of AS 1973 1993 - 'Pneumatic tyres -Passenger Car Light Truck and Truck/ bus -Retreading and repair process' or as amended from time to time.


VSB1 deals with building new trailers, not modifying them. It is a general rule of thumb that wheels & tyres fitted to a road vehicle must be of a type and combination match as listed in the Australian Tyre and Rim Manual.

If a tyre is listed for NHS & it is picked up by a Roadie or a smart copper ( ) the a defect will be had.

Why risk an uncertified tyre for highway use?

[mkpatrol]

I just had a chat with a workmate and found out there is a new VSB1 on the way which indicates that the tyres must comply with ADR's 23 and 42.

ADR23 is for passenger car tyres & gives the standards that the tyres must comply with.

ADR42 reads like this:



25. TYRE AND RIM SELECTION
25.1. Tyres and rims recommended for passenger cars must be listed in the
Tyre and Rim Standards Manual published by either the Tyre and Rim
Association of Australia, the (US) Tire and Rim Association Inc. Year

the Japanese Industrial Standards (JIS-D4202) “Dimensions of Tires”
and (JIS-D4218) “Contours of Rims”, or the European Tyre and Rim
Technical Organisation (E.T.R.T.O.) Data Book.
25.1.1. The ‘Administrator’ may accept a tyre, ‘Rim’ or tyre and ‘Rim’
combination not incorporated in the above publications.

25.3. Requirements for L-Group Vehicles
25.3.1. Carcass Construction
All tyres fitted to an ‘Axle’ must be the same type of ‘Carcass’
construction, but may vary in respect of ‘Cord’ materials and number of
‘Plies’.
25.3.2. Load Capacity
The sum of the load carrying capacities recommended for all tyres and
‘Rims’ with which the vehicle is equipped must be not less than the
‘GVM’.
25.3.3. ‘Maximum Load Rating’ of tyres must comply with those listed for the
tyre size designation in one of the ‘Nominated Standards’, or the tyre
manufacturer’s warranted maximum tyre load.
25.4. Tyre Placard
MA, MB, MC, MD, NA, NB1, TA and TB category vehicles, must be
fitted with a tyre placard which, includes at least the following
information: manufacturer’s recommended tyre size; tyre load rating;
speed rating and cold inflation pressures.

Same rules apply to trailers as apply to vehicles.

Some tires are marked "NOT FOR HIGHWAY USE" and if you put them on a trailer it will be stickered if it is used on the road and then you have the hastle of going getting it inspected and correct tires as per the placard.

If the tires are low on tread and not leagle on your car then dont use them on a trailer.

Thats the way it is in WA and probly every other state as well...
