Seem to remember a few people thinking that the local stealership is once again trying to rip them off when they have new tyres fitted and get new tubes without asking.
Yes you should be informed, and not just given the bill. But here is why you should have 'em.

Good thread. Pertinent to Post Classic restos. Buy a bike on Tardme to remind you of your misspent yoof. Tyres are old & crappy. Should know better & replace them. But inner tubes on that old bike will have been sitting perishing for years too.
Don't you look at my accountant.

Yep. While we're at it. Fitting a tube that's too big cause it's all you can get. That too is a no no. Same result as the old tube for obvious reasons.

Find it hard to believe an adventure bike, especially one that's been on a world trip would have original tube still, would have more patches on it than Windows 8...
The same thing can happen with new tyres/tubes and tubeless with a slow leak puncture. On the move you've got centripidal force expanding the tyre and the engine shifting plenty weight to back wheel, fronts not doing much until you brake or change direction.
We don't need yet another nanny state law...
And how often does this happen in real world?

I would have thought from reading details of his career that Mr Wyness was a smart guy, but if he was in fact using a nine year old tyre that was definitely not smart.
That tyre would have been about as sticky as a plank of wood.
Umm and sorry, I can't remember. What form does the median barrier take at Rangiriri? Is it concrete or wire?

I wonder if he would have lived if it had been a concrete barrier rather than wire rope?Was his fatal back injury caused hitting the deck or
hitting a wire rope support post?

Tyre TUBE not tyre.
When we used to use tubes in Buckets & run the old Yoko 110s at 16psi to get some heat into them, they'd squirm & deform like all buggery even on a 70kg bike with <20hp but it was the only way to get grip on kart tracks. Trade off was inner tube life. they would chaff. before a 2hr we'd change the inner tubes as a matter of course & douse with talc. Those that didn't were usually over represented in the punture stats.
Some of the tubless slicks were quite rough inside, but rims prevented going tubeless. Quality of tubes varied quite a lot too.

Who's talking about nanny states? I'm talking about taking due care to look after your tyres/tubes in case it may help someone avoid a nasty acc. Trust me...I've seen plenty of tube horror stories over the years.

Omigod - that was a scary read....44 years on the road with tubed tyres, it must be a miracle that I'm still alive! I need a little lie down after that, I'm all in a cold sweat wondering how close I've come to losing my life. Not only my own life, but there are possibly hundreds of people who've died without me knowing when I changed car and bike tyres using old tubes.

Yeah well do we agree with the conclusion of the Coroner? Basically any flat tyre when you have a tube occurs in quite quick time, so any puncture could have caused the same outcome no matter how old the tube. So what is the solution - ban all tubed tyres?
I understand though using as new a tube as you can would diminish the chance of a flat due to the chafing thing, but how that compares to the chance of getting a flat due to a nail or some other sharp object on the road I don't know - I'd guess its like a 10% to 90% chance sort of issue.
Brian was a top bloke and we discussed this crash back at the time without knowing much of the detail here http://www.kiwibiker.co.nz/forums/sh...median-barrier
Then a question, when I last replaced the tube on the front of my XR250L, Motomart convinced me to buy a "heavy duty" tube but I have found it seems to lose air with time faster than I'm used to - is this normal for the heavy rubber type as its not something I've had so badly with "normal" tubes?

No need to get quite so carried away about it Old Bean, you don't do sarcasm so well. But how many of your vehicles have you run tubes in that do and have done 150mph? And yes...I know the BMW in question couldn't.
Smarty pants... since ages ago
Nothing mentioned about needing to change laws ... more of Policy/Practice of the tyre industry that needs change ...
How many times does it need to happen before you decide some change is needed .. ???
Until a family member ... or a friend of yours .. suffers the same fate ... for the same reason .. maybe ...
Would he have been better off hitting the car ... would that have been easier/softer option for him .. ??

Crasher,
What sort of percentage of bikes are now sold with tubed tyres?

easy to work out yourself isnt it?bikes that still have spokes is my guess?i dont think the tube thing should be brought up as an issue,unless they want to enforce tyre and tube manufacturers to put use by dates on thier product...
the issue is he came a cropper going slow and died as a result of what?
maybe a wire rope?
