Just had my 285/75r16 tyres balanced and had the fitter say they are 50mm over legal size, I cant work that out he said they are put to much strain on the car????

RUBBISH!

You can fit legally a tyre that is 2" bigger than the Tyre Placard and also fit a 2" Suspension lift without any repercussions. He is a Goose. Your car will handle a 285 in its sleep! I run 315s and have no trouble at all.

285's not a problem at all
No lift required, maybe mudflap removal
the only thing thats wrong is the speedo and only by 3-5 km
over a 300km trip he was short 13km

Sorry if this is a thread steal but on the same unlifted GU3, running the 285/75r16, would it be best to run a -22 offset rims. (cruider rims)

i used to run -22 offset on my gq and i liked the wide stance but i'm worrid about rubbing the outer guard.

thanks in advance.

Thats Adelaide for you, everything is to hard if its not standard,he was the manager of Bridgstone Tyres and he even rang someone else up?

He was probably right. I am not sure about the laws in SA but in NSW at the moment you can only have a 15mm increase in the outer diameter over the standard wheel and tyre combination (what is written on the tyre placard). Anything bigger and you are off to the engineer to have them certified as legal. Some states have already adopted the new regulations that allow for a 50mm increase to be done without the need for certification but not all. NSW hasn't and there is no guarentee that they will. So no 50mm increase is not necessarily legal.

[Aquaman]

My experience with Bridgestone is that the guys and gals are usually spot on. A lot of places will just fit things and not tell you if they are legal or not. If they are not legal then you are technically driving an unroadworthy vehicle. The insurance company could refuse to pay any claim regardless of if you are the driver at fault. The Police could book you. If there is an accident and someone is hurt or killed then you could be in all kinds of $#%*.

If i were you i would be looking into it just to make sure.

Going from a 265 to a 285 should only give you about 20mm overall rolling diameter not sure how anal they are but 5 mm isnt exactly a lot.

Not quite.

265 to 285 would be a 20mm increase in width not diameter.

The overall diameter will depend on the aspect ratio. For example a 265/70/16 to a 285/75/16 is about a 56mm increase in overall diameter. The aspect ratio is the 70 or 75 bit in that example. It is a percentage of the width and tells you size of the sidewall. There are two sidewalls one at the top and one at the bottom. Add those the the size of the rim and you have basically got the overall diamater.
