Flat performance question

Apparently most bike street tubless tires are designed to stay on the rim if
they go flat, a few aren't. In the sense that you can hobble along at
walking speed for quite a way and not wreck the rim. The tire will be
hooped, but at least it stays on the rim and the rims OK.

I had a link once to a table giving this information but lost it.

I was wondering if anybody has a link to this info if they wouldn't mind
posting it.

Thnx

Pete.

It's not like they're deliberately *designed* to stay on the rim. It's
just that modern radial tyres need really stiff sidewalls, and also have
a low aspect ratio, so they just tend to do so naturally.

Never *heard* of the table to which you allude.

I once rode about ten miles on a completely deflated Michelin front
tire, but I wouldn't want to try that on a deflated rear tire.

Bridgestone has an English language pamphlet on their Japanese
language website which states that their tires have had "run flat"
capability since the 1980's.

You can find the pamphlet if you google for "mcintroe.pdf"

(If "The Older Gentlman" wants to argue with Bridgestone engineers,
he's welcome to do some investigative reporting, instead of
bullshitting with opinions on Usenet.)

In general though, you can tell if a tire is likely to stay on the
rim. Radials, with a
low, stiff sidewall generally will stay on the rim even if deflated.

Bias-ply tires with a taller profile and very flexible sidewalls might
stay on the rim, but it would be very hard to control the motorcycle
once they were flat and the
sidewalls curled down into the drop center of the rim.

No, it doesn't. We've done this before.

Yes, you can.

I'm not arguing with them, I'm arguing with you. They do not state their
tyres have run flat capability.

Read the file yourself.

End. Of.

You can just about hobble home on a flat modern tyre - I managed to
hobble home more than once on a flat antique tyre - but the tyres aren't
run-flat in the accepted sense of the term. Check the link I posted
again.

However, the entire world has not accepted Neil Murray's personal
point of view
which uneasonably requires "run flat" motorcycle tires to meet the
same standards as car tires.

There are other riders who are reasonably satisfied with current
motorcycle tire technology, which allows one to safely reach the side
of the road, stop, and apply
a temporary repair that gets them home or to a repair facility.

Yes, it has. It just hasn't accepted *yours*.

Here's a challenge for you, if you think otherwise. Show me a tyre
manufacturer advertising "run flat" tyres for motorcycles. Off you go.
There are loads of companies offering run-flat tyres for cars. But
bikes?

That is not what a tyre claimed to be "run-flat" is accepted by the
entire tyre industry, and consumers worldwide, as providing.

You lose.
