Are 35's legal in Qld?...Went to two tyre places over the weekend and asked the question but couldn't get a yes/no answer. More of a dont know. Does anybody know? Also will they rub on a gq with a 3 inch lift and offset 8inch rims?. Cheers. (did a search but couldn't find info I was after)..

no

in qld its +/- 15mm from the largest standard tyre shown on your vehicles tyre placard..... so no

actually i thought it was +15 and -21...?

could be wrong though...

Ive got a 5" lift with 35s on my shorty gq and they rub, so presumably they will rub on a 3" lift

i thought that it was 33" on road

35" offroad ???

not road legal in qld .
yes they will rub on front guards at mudflap.
if you want some for off road $800 for almost new muddies

cheers johnz

+15/-25mm.

33's on a GQ are not roadworthy.... too tall (seriously)

And any sort of rubbing/fouling on steering/suspension is also illegal.

No I don't think so it all relates to wether or not the new tire is greater than 15mm than OME in overall diameter.

Copied from Qld Transport document:

Lowering or raising of vehicles

The road clearance of a fully laden vehicle must not be
less than 100mm measured at any part of the vehicle
other than the wheel rim or brake backing plates.
(This does not apply where a lesser clearance has been
specified by the manufacturer.)

When lowering or raising a vehicle body (front or rear),
the following additional restrictions are based on the
manufacturer's dimensions for the standard unmodified
vehicle while unladen:

• The ride height measured between the rubber bump
stop and the corresponding metal stop may be reduced
by no more than one third.
• The rebound travel measured between the rubber
rebound stop and the corresponding metal stop
(or the extension of the shock absorber for vehicles
without a rebound stop) may be reduced by no
more than one third.
• Coil springs are to remain in locating seats on full
suspension droop without forcibly being removed.
In addition, the normal relationship between the front
and rear suspension heights must not be unduly affected.
Replacement springs (shorter or taller) must have the
same or greater load capacity as the original springs.

Suspension coil springs must not be shortened by cutting
or heating. Leaf spring suspensions must not be raised
by the use of extended shackles, adjustable metal plates
or by placing the leaf springs to the opposite side of the
axle. If lowering blocks are used, they must be either
steel or aluminium.

Airbag or air pressurised shock absorber helper springs
may be fitted in addition to the original suspension.
However, replacing some or all of the suspension system
with an air or hydraulic suspension requires specific
approval.


Alternative rims and tyres

Many vehicle owners like to replace the vehicle’s original
rims and tyres with alternatives of different width,
diameter and profile.


The following sub-sections outline the legal requirements
for replacement rims and tyres fitted to a passenger car
or derivative, or an off-road passenger car (but not light
commercial), which will ensure your vehicle continues to
comply with Queensland legislation while allowing for
your individual preferences.

Low profile tyres

It is common practice for manufacturers to fit low
profile tyres to high performance motor vehicles as
standard equipment.

Low profile tyres (e.g. 50 series), replacing standard
profile tyres (e.g. 70 series or above), are normally fitted
in combination with rims of larger than standard
diameter to maintain the correct overall diameter of
the wheel.

STANDARD TYRE LOW PROFILE TYRE

The rim diameter may be varied from the standard size
but the overall diameter of the tyre must not vary by
more than +15mm or -26mm.

These limits have been set for a number of reasons.
Varying the overall diameter of tyres affects ground
clearance, centre of gravity, brake effectiveness, steering
geometry, performance and speedometer accuracy.

Generally, to meet these limits, 60 series tyres are fitted
to rims with a diameter 26mm larger than standard and
50 series tyres are fitted to rims with a diameter 50mm
larger than standard.

General conditions for
alternative rims and tyres

The rims and tyres must not protrude beyond the
bodywork of the vehicle, including flares, when viewed
from above with the wheels facing straight ahead. If the
vehicle was originally constructed with a portion of the
wheel protruding, the wheels must not protrude further
than originally constructed.

The tyre to rim fitting and the tyre to rim combination
must be in accordance with the Tyre and Rim Standards
Manual published by the Tyre and Rim Association of
Australia. Reputable tyre retailers should have this
information and be able to advise on the correct
combinations.

All rims fitted to an axle must be of the same diameter,
width and offset. They must not have a circumferential
weld other than that which attaches the outer rim to
the centre. All rims must have stud hole pitch circle
diameters suitable to the hub. Wheel nut tapers must
be appropriate to the wheel and must engage the thread
of the wheel studs for at least the same length as the
nuts provided by the vehicle manufacturer.

Slotted and elongated stud holes are not permitted.

The fitting of spacers or adaptors between wheels and
hubs, additional to those provided by the vehicle
manufacturer, is not permitted. The tyre and rim must
not foul wheel arches or suspension components under
any conditions. Steering limit stops must not be adjusted
to reduce the turning circle in order to allow the fitting
of the alternative rims and tyres.

The tyres must have a tread depth of at least 1.5mm on
every part of the tyre that touches the road and not have
any apparent defect that is likely to make the vehicle to
which they are fitted unsafe. It is not permitted to fit
tyres that have been treated by recutting or regrooving
unless the tyre has been marked by the original
manufacturer as ‘suitable for recutting or regrooving’.

Tyres

The maximum tyre width for a car or car derivative must
not be more than 1.3 times the vehicle manufacturer’s
widest optional tyre.

However, for an off-road passenger vehicle fitted with
front and rear beam axles, the maximum tyre width
must not be more than 1.5 times the vehicle
manufacturer’s widest optional tyre.

The nominal width of the narrowest tyre fitted to a
vehicle must not be less than 70 per cent of the nominal
width of the largest tyre fitted and never less than the
vehicle manufacturer’s narrowest optional tyre as
indicated on the manufacturer’s tyre placard.

You could argue that that only applies to low profile tyres as that is the sub-section.

4x4 tyres in the main are NOT low profile so therefore does not apply.

The rule is max 15mm larger in diameter, but some DOT officers have been allowing 33's on GQ's etc, but some others won't.
if they take the std GQ tyre as being a 7.50 x 16 on a split rim, then you mighty just scrape into fittng a 33 and being legal.
35's definately not though. plenty of people run them but 1 day they will get caught.

Short answer......................aaaaaaaaaaaaaahh NO!!

Is it still a no if the vechile was engineered? Will any Engineers ,engineer it in Qld? NSW still have the 15mm rule but so many people run 35inch tyres here and its ok so long as its been engineered.What about if i had a vechile with 35inch tyres here and its been engineered here and approved and i moved to Qld then can i have it?

they are legal on the brand new gu's they come stock with 33's

new gu's come with like 255/70r15. which is closer to 30'' champ.

largesuzy wrote:they are legal on the brand new gu's they come stock with 33's

not a chance, I've got a new GU and a Coopers rep told me they are close to 33", they are no where near it, more like 31's.

If you move to Qld from NSW, and have your vehicle approved for that state then you have I think it is 3 months to get your rego transfered to Qld plates, which will mean a Safety Certificate and most likely and inspection so it won't pass up here.

cheers for all replies to my post, have definitly answered the question, will stay near legal and get 33's me thinks..

In doing some research I found this great tyre calculator which converts metric to US , vise versa, and compares multiple tyre sizes...

Hmmmm.....

Yep, I think my rig breaks all of those codes

Just kidding, Officer...37s are ok though, aren't they?

Micka

Time for a communal OL property somewhere out in "Hicksville" Victoria, one with a very large letterbox.

"Officer, my address is XYZ in Victoria. I'm just doing some contract work up here".

Vic licence, Vic rego, Vic engineering....Can't argue with that.

my gq only has bout 3" lift and I got 35s. just can't have factory flairs or mudflaps.

35's are legal in qld, on cars that come with 35's (or 34.5's)!


Interestingly the NCOP (National Code of Practise) will be assuming QLD's rules for tyre and suspension modifications.

What car came with a 35 on it ?

No cars, plenty of trucks, not many 4x4s - those that I know of:

Land Rover 101" Forward Control (9.00x16)
Volvo C303 and C306? (9.00x16??)
Land Rover One-Ton (9.00x16) - not 100% sure if any of these came to OZ.
Land Rover series IIA and IIB Forward Controls (9.00x16)
Various Unimogs - 35-38" wheels usually

even if they did come with 33's you still couldnt fit 35's, thats a two inch rolling diamater increase. and when i was a boy 2" was about 50 mm, and still while i was a boy 50mm was more than 15mm

I dont think its really worth pretending to be Victorian though

But if you have an engineers certificate stating that 35's are complied on a vehicle, does this in effect then become the new tyre placard? I think you could argue this in a court.

So, assuming the above, if you have an engineers report stating 35's, it then becomes + or - 15mm from 35".

Having said that, I have found someone the will give me a QLD road worthy with my 35's. But I have an engineers report.

Reasonable question.

If an interstate engineer had complianced the vehilce and fitted a tyre placard stating the vehicle is allowed 35's, would that hold up if the vehicle and owner moved up to Qld (or elswhere)?

Thats great but then take your roadworthy and Engineers Certificate down to a Queensland Transport inspection Station and let them take a look at the car. I guarentee you will leave with a defective vehicle and an Engineers Certificate thats not worth the paper its written on. And the Guy who did the roadworthy will be getting a Visit from Queensland Transport very soon after.

In QLD if Queensland Transport have not approved the Modification no engineers cert is going to change it.
