More on tyres and wheels for 80 series

And looking further, why does one placard state:

A speed category symbol of not less than "H"

and the sticker below it:

The tyres fitted to this vehicle shall have a speed category not less than "N" (140km/h).

Thanks for posting the placard it was very useful. This means that the total height/diameter reccommeded by toyota is 800 mm. I have 305/70's on 16's and they are 827mm 2.7 cm too tall therefore mine are illegal in Qld. I wonder if I will now need an engineers certificate does anyone know?

By the way 285/75's come to 827.5mm so are also illegal in Qld.

My tyre dealer said nothing about my tyres being illegal on Qld roads I find that very interesting.

Thanks Andrew, clears up my query.Cheers,

Tristjo the latest Queensland Transport modifications guide (that I picked up today) states that the overall diameter of the tyre must not vary by more than +15mm or -26mm than the largest on the tyre placard (or that the manufacturer recomends). More interestingly it states that for the width of the tyre it cannot be more than 1.3 times the max width on the placard for passenger cars and 1.5 times on off road passenger vehicles with front and rear beam axles (provided that they stay within the bodywork/flares). That means for an 80 series with a max of 275 you could put 401 tyres on. That sounds pretty extreme to me pitty no one makes them that wide with the smaller diameter.
