So the fact that there was tire ground out for whitewall purposes does not hurt the tire one bit? If so I have made a fail thread.

I wouldn't think so man when i had mine done the amount they ground out was about 1mm. Blow outs happen that's life. IRS and camber doesn't help.

Suppose, I had a look at these and there was a fair bit ground out, that why I thought it was the walls, theres decent rubber missing on the tire where the walls lived, the IRS doesnt help at all extra stress that the tire doesnt need. EVen thou with a good tire it can happen.

i understand what Raptor is saying and there's truth that it propably does weaken the side walls... but i dont think its enough to make a properly load rated tyre blow out like that Some original photos have not been recovered yet.

I can't see how it'd make it blow out either, a sidewall isn't the last line of defence, if anything the sidewall is the barrier that can take the abuse. It protects the inner linings and belts of the tyres. I think somebody needs to get an old tyre and chop it in half and measure it. Or people with walls that haven't failed, have a good look for signs of stress or any cracks, wearing, warping that's happening. I fail to see how overly stretching a tyre, under inflating, overinflating, using tyre shine, or driving a car with gutter rashed wheels and tyres is any different. I had a brand new tyre fail on me, it had developed a leak, and went down, I was at the servo when it was about 1/2 capacity, pumped it back up, leak stopped, but damage was already done to the tyre, couldn't see it on the outside, but it had warped and was wearing on the inside. 1 tyre out of however many are out and about - with tyres blowing out all the time worldwide, I'm not jumping to conclusions here. I might swing a few emails off to some tyre manufacturers later today and see if I can get a response.

I find this thread quite entertaining really. My mate is a restorer/trimmer and he has a whitewall machine and the amount of rubber they take off is more than 1mm. There is a reason why any gashes in your tyres be it from scrubbing your guards, guttering or worse. It weakens the side walls. Take one of the trucks I was unloading over previous summer, he had a small nick in his tyre from one of the metal lands and progressively as we were unloading this truck the nick turned into a bigger and bigger slice.... Only reason I dont think it actually popped was the RTA made him change it when they pulled him over.... But seriously guys, do you really think that changing the structure of a tyre is good for it? They are made a certain way for a reason, they are designed to take certain stressed and wear and tear... But i guess it comes down to being like women and shoes... If it looks good who cares what it does to you.

I've sent some emails off to see what kind of wear, strength, integrity information about sidewalls. Bridgestone Kuhmo Pirelli Continental Michelin That's who is getting the email. I'm assuming most will say that it shouldn't be damaged at all, but hopefully some will provide a non legal covering their own ass response.

Trust me there was a fair bit of tread left, use dont understand that sidewall went like it was on 2PSI and the other end of the tyre was FIRM. Until it blew out like that I know how this tyre has **** itself and its definatly the whitewalls.

I agree with Munro and Raptor. You are decreasing the thickness of the wall, making it weaker. As a mechanic, tyres the had noticeable nicks or chucks taken out of the sidewall, or hanging loose, would not pass RWC when I inspected them. These chucks were often up to 5mm deep, obviously more than a whitewall channel, but smaller ones are still a sign of weakness in a tyre.

Let me guess 225/30/20 tyres on a commodore?

porta loo

245/35/20 Falken dont make a 225 i dont think Some original photos have not been recovered yet.

Interesting thread!

I just spoke to my police mate at moorabin TMU, and he just told me specificly if they see whitewalls on a car, no matter what size tyre. INSTANT defect. Major and needed in a RWC. obviously the rest to if its too low, etc. etc.. Look i love walls personally, ill still get them, but this time KEEP an eye out for them

low profile tyre walls are so thick! worst putting them on 19's i would hate to put tires on like a 24 inch rim with a super low profile Quote: Originally Posted by OldGold Interesting thread! hard..

i agree with raptor aswell. i used to think that walls where just drawn on with a texta and that was it, when i found out the shave of rubber i could see how that was safe at all.. that rubber on the side is there for durability and helps under stress wen turning. as much as i think they look cool i think the vic gov actually made an intelligent law regarding cars for the first time since i can remember. even if the walls didnt course the blow out i dont doubt for a seconds that the dont weaken or crack the tire in anyway. a cracked tire is a busted tire!

Am I missing something with that link? It doesn't say white walls are fine BELIEF.. please.. belief.

doesnt matter how careful you are, a DAMAGED tyre is a defect waiting to happen. People expect you to believe that cutting the sidewall is fine, yet grooving the tread for a few thousand more k's is illegal on a passenger car. Take any of the designated load info off the tyre even if the sidewall remains untouched, thats a defect too so i cannot comprehend how a groove all the way round the sidewall is legal anywhere. If they were adr compliant, the manufacturers would be selling them...If they do and you dont like that style/size of tyre its bad luck, you cannot "deface" a tyre for the purposes of suiting your needs. Removing material from a (passenger) tyre is illegal, pure and simple. Youll see a lot of defected cars because of it, simply because its the easiest and most visible from a distance means of identifying a non compliant car.
