joker97: Are you driving a Ferrari or something


Often the 4 for the price of 3 deals come at the expense of any other discounts. So the unit price jumps to full retail.

On my tyres the sidewalls have a sacrificial band of rubber about 6mm thick to protect the sides and the rim. Minor damage to this band of rubber would not affect the strength of the tyre.

It seems the experts (who set the WOF rules and vehicle standards laws) disagree, or at least have set a limit on the amount of damage a sidewall can sustain before the structural integrity can no longer be assured.  The sidewall is an integral part of the suspension and stability system in the car, any  weakness can potentially lead to failure.  Personally I wouldn't risk it, my life and that of my family is worth more that a couple of hundy for a new tyre.

We have pretty high standards. No WOFs in Australia until you sell your car.

And here if there a one chip of glass of any size over the driver's side of the windscreen you can say goodbye to driving until you pay a thousand bucks.

Yes the limit is a cut longer than 25mm that exposes but doesnt cut any cords. The rim guard band is additional to any rubber that would cover the cords. I think you are looking for problems that don't exist.

Depends where you are.... In Vic, you need a roadworthy cert when you sell it. And they are waaaay more thorough than any WoF. Takes them a couple of hours to go over a vehicle.
3 (may be more) or more "pits" in a windscreen in an area of 20mm circumference, and you'll need a new screen. Old oil on engine like it has leaked, fail.

In South Aussie, if it's registered and you sell, you don't need to have it checked. BUT it's up to the driver of the vehicle to maintain it in a roadworthy condition. Big fines, all the way to impound (depending on circumstance) if it's not.

Really? They are usually repairable by that novus system,. I had one and got it repaired and it was on the drivers side, and was free under windscreen insurance.

Not if you have any half-decent insurance... then it's free

Actually windscreen price is not as high as you thought (it used to be expensive in the past).

The last two windscreens I had replaced, cost just over $400 at Smith and Smith...

I recall reading another thread on windscreen issues, and some windscreens are now imported from china and may not be as good a quality optically.

I am a vehicle inspector 
if you can see the cords behind the tear its a possible fail 
if you can see the cords clearly and one or more are cut then its a fail
tyres like the photo you supplied are very thick there as protection for your rims so it is not likely you have got near the cords at all
if you have a tyre shop you use for your tyres pop in let them use some of there punture repair glue to glue it back down chemical vulcanizing should be a free fix
also some pushbike punture kits have small tubes of the same glue if you have any of them lying around

but in my opinion from photo its not a fail unless you lift that flappy bit and look under it

johnr: Side wall damage is only an issue if steel belt is damaged if not then you are throwing money away, The strength is in the steel belt not the rubber

If tyres have bulge then get it changed ASAP and don't even use it as a spare tyre



if theres a bulge it has broken radial cords and yes its a fail and as above get it changed asap 

also steel belts are only on the tread area of tyres not on the sidewalls, sidewalls only have usually nylon cords

You think the diagram is accurate to the millimetre? In the diagram everything stops in the middle. Surely some of them extend to the walls of the tyre. But i know nothing about tyres other than ... Pilot Super Sport and F1 Asymmetric 2.

joker97:
jonathan18: Something similar happened to me the other week - and I discovered it a couple of days before my WOF was due. I called into the only store that stocks the current tyre on the car, and they checked it out and said it would be fine and would pass the WOF without issue. In my case, only rubber was visible under the 'gash', so you may face a different outcome. But I'd totally recommend just calling into a tyre place to have them check it out - but perhaps one that you trust, rather than one of those that appear to do anything to increase the chance of a sale...

And, yes, my car passed the WOF without issue, which I was damn glad about given I got a quote for new tyres at the same time: $1600 (or thereabouts) for four tyres (at that point they were doing 4 for the price of three, so the full price was something like $500 each!).



Are you driving a Ferrari or something


I wish! (Though don't know where the two tykes would sit if I could afford that!) Nah, it's just a Mazda 6 - but being a Limited, they've got 19s" on them:



The tyres fitted on these wheels are some weird Firestone or Bridgestone model that's apparently only used for the 6. I'm yet to go around the other tyre places to see what options they have, but at that cost I doubt I'll be buying the same tyre! Luckily, still got a good amount of tread on them so I don't have to face this in a hurry (unless I damage them further...).

Must be a hard ride! I hope mine 18" are not that crazy expensive. If so i will sell my ruins and get new 17" for a more decent ride :)

Well I can tell you this Radial tyres do not have steel belts on sidewalls 
most tyre companies buy the cases in and then add there belts then the rubber and then put them into there moulds that puts the tread pattern on
all Z rated tyres the ones you need on fast sports cars have hand made cases thats why there expensive
I have a long history in motorsport in NZ I have also been involved in tyre companies mag wheel companies parts importing and manufacturing engineering and vehicle certification LVVTA if you have any doubt just pm me your questions
