Are 33"s Illegal on a 80 series?

[Thommo 73]

QLD sucks

but arnt the standard split rims and tires 32.4"

[Matt_85Lux]

but arnt the standard split rims and tires 32.4"

No, standard split rims use either a 7.50R16 or 235/85/16 which are no taller than 810mm or 31.88"

[Shadow]

I dont think they can go off the size of the tyre on the sidewall, thats just stupid and I would challenge that immediately.

I have spoken to the QLD transport inspector at the Bundal customer service centre, and he measured my tyres when I had 33x12.5R15 Kuhmo AT's on my HJ60 and he told me that they are fine.

He ignored what the tyre sidewall said, and said it was the "rolling diameter" that the legislation refers to.

This was over a year ago, but I cant imagine anything has changed.

but arnt the standard split rims and tires 32.4"

No, standard split rims use either a 7.50R16 or 235/85/16 which are no taller than 810mm or 31.88"

a 7.50R16LT tyre According to the Tyre and Rim Association Manual, has a rolling diameter of 808, Highway tread, or 819, Traction tread.

There was a thread recently where someone was told by QLD transport that the Traction Tread doesnt apply to vehicle for onroad use (even though the section in the Tyre And Rim Association manual SPECIFICALLY states "Light Truck Tyres for Trucks, Buses, Trailers and Multi-Purpose Passenger Vehicles used in Normal Highway Service"

So based on that, if your Tyre placard says 7.50R16LT you can legally go to a tyre of 819+15mm = 834mm.

My 33x12.5R15 kuhmos measured something like 819mm.

For a 33x12.5R15 tyre the Tyre and Rim Association manual says the rolling diameter is 826mm for Highway Tread, and 832mm for Traction tread.

So, If they refer to the Tyre and Rim association manual, it says you CAN legally use 33x12.5R15 tyres on a car which was origonally fitted with 7.50R16LT tyres.

If you measure your 33x12.5R15LT Tyres They will in alot of cases legally comply to the +15mm rule. (if they are bigger you could just say "look at the tyre and rim association manual, it says my tyres are legal and thats why i baught them")

So wether they measure it (will probably be smaller), Or if they Look at the sidewall (says 33x12.5R15LT), The tyre will comply with the +15mm rule.

Also, as all 60 80 and 100series had the Pov Pack model with 7.50R16LT tyres fitted as standard, this applies To all these models as the modification guidline says the largest tyre origonally fitted to that model.

[Shadow]

For width it is 1.5 times the "Manufacturers Widest Optional Tyre) for beam axles

and 1.3 times for IFS, so as 100 series IFS came with 265's, can go to 344.5mm (13.5") and 60 and 80 and 100 Rigid can go to about 15" wide tyre.


33x12.5R15 has as ection width of 318mm according to the T&R Assoc Man, which easily complies for ALL landcruisers.

Does it? CAN you?

Isn't the 12.5 inch width going to be too much of an increase in width over the width of the 7.5R16LT?

I thought we were limited to a 50% increase in tyre width?

33x12.5R15 has as ection width of 318mm according to the T&R Assoc Man, which easily complies for ALL landcruisers.

Nope, a cruiser with a 7.50R16 standard tyre has a section width of 191mm, an increase from 191mm to 318mm is more than 1.5 times or 50% increase.

So, a 33x12.5R15 DOES NOT easily compy with ALL landcruisers!

I answered your width question above.

as for "Does It, Can you"

Do you want me to post it again?

I have a Tyre and Rim Association Manual infront of me.

This is what QLD Transport use for thier compliance. I am pretty sure it is the nationally recognised standard and recognised by all state transport authorities. I know the RTA refer to it aswell.

This is all in writing, how can they challenge what is written in clear and concise english and contained within the standard they use for compliance?

7.50R16LT has section width of 202mm for starters.

Widest Optional Tyre is what the QLD MOdification Guidline refers to.

60 series had optional 31x10.5R15 tyres
80 had wide tyres optional too (not sure what size they are, assume 265/70R16 and R15)
and 100 series has 265/70/R16

So yes, it does, easily, comply, with, all, land, cruisers.

Sorry, but my 70 series Land Cruiser only had 7.50R16 as standard, nothing else.

It doesn't matter what the widest optional tyre was on a particular series of Land Cruiser, it is taken as the widest optional tyre on that exact version/year of the series.

The widest tyre on my LAND CRUISER is a 7.50R16, which you say has a section width of 202mm.

A 33x12.5 has a section width, as you say, of 318mm.

To me that seems like it is more than 1.5 times the section width of the largest originally available optional tyre size on my LAND CRUISER.

It is a year 2000 HZJ78 Land Cruiser Troopcarrier.

Apparently the 7.50R16 is the only size that was available on my model in Australia, which seems to match the list of optional tyre sizes in the factory service manual.

The factory service manual lists 235's as an option in New Zealand, but that is no use to me here in Australia, where the only option shown is 7.50R16.

I believe that they go by the tyre placard on your car, which in my case, also shows only the 7.50R16.

I can not use the tyre sizes on later 70 series with wider tyres, such as the HDJ78, as it is a different model.

The tyre placard will only show what tyre was fitted to the vehicle when it was delivered to Aus.

For a 60 series, if its a GXL or VX spec it would say 31x10.5R15, Pov pack says 7.50R16LT.

However, in the FSM it does list all the optional wheel/tyre combos as you say.

If you do go off a 7.50R16LT tyre though, with a nominal diameter of 202, means you can go to 303mm, so a 33x11.50R15

[SimonInAustralia]

This is what you said...

So, If they refer to the Tyre and Rim association manual, it says you CAN legally use 33x12.5R15 tyres on a car which was origonally fitted with 7.50R16LT tyres.

33x12.5R15 has as ection width of 318mm according to the T&R Assoc Man, which easily complies for ALL landcruisers.

Now you are saying this...

If you do go off a 7.50R16LT tyre though, with a nominal diameter of 202, means you can go to 303mm, so a 33x11.50R15

...which is not the same as your first claims.


You get shitty with me for questioning if what you are saying is true, because you have a Tyre & Wheel Standards manual, you think you are some sort of expert...

Do you want me to post it again?

I have a Tyre and Rim Association Manual infront of me.

Fark dude, if you are going to claim to be some sort of expert, making blanket statements about what is legal or not legal for ALL Land Crusiers, at least make sure you know what you are talking about.

No mention of any Land Cruiser there, your incorrect advice seems to be for any car.

That really depends on the width and offset of the rims used, rather than the tyres, but yes, wider rims may be needed/desired for the wider tyres, and/or a different rim offset, which might put you over the maximum track increase limit.

But Shadow knows better, he has a Tyre & Rim Standards Manual!

[Shadow]

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.

no mention of tyre placard

And I have yet to see a tyre placard that displays all the optional tyre/rim combinations for a model of vehicle.

Simon is correct, you will need to check what tyres are optional for your vehicle.

For all 60, 80, and 105 series, 33x12.5R15 are legel.

For a 100 series, since we are getting technical, I dont think the 100 series ever came with 7.50R16LT as the pov pack 100 series doesnt exist (its a 105).

what do you think they look at when you get pulled up and they do a proper check? I have seen the coppers check placards before and give defect notices for not having one.

As I stated numerous times in this thread while33s oare technically illegal on a cruiser they very rarley enforce it same s 31s hiluxes or are they legal as well?

It is a an ADR requirement after think 1980 or 79, to have a tyre placard.

The tyre placard does not show every optional tyre for that model of car, it shows 1 tyre and wheel combination.

Why would they write the guidline, saying, the largest optional tyre, if they meant "the tyre fitted when built".
