    Technically true, but closer to bullshit. I believe the average figure for air permeation through tyres is 0.067psi per week, or 1psi every 15 weeks. Any more than that is an integrity problem, not a permeation problem.

    Now that's true.

    Unless you're trying to shave seconds off your Coro Loop or Akoroa GP times, exact figures are a load of shit.

    Ball park figures are all that are required for conservative riding.

    I had a fast deflating front tyre puncture on a xr500, it went flat while I went down a 400mtr straight downwards incline leading to a moderate corner (tarseal) as I flicked the bike over into the corner at approx 100kph, I felt the odd sensation of the tyre trying to fall off the rim, even remember the sound of the rim scrapping the tarmac , just before I slammed shoulder first into the tarseal, lost a fair bit of skin that day as I only had track pants and a short sleeved shirt, + sunnies , but no helmet, even skinned my back around the shoulder blades,
    no thought of consequences when I was young ...

    I hear you. I use that story merely to highlight a point.

    Your story reminded me of a vivid memory although totally different as the tyre didn't go flat and was the rear but it must have been 1980 coming down from Wrights Hill mx track area I was dubbing a mate, neither of us were wearing and helmets let alone long sleeves I decided last minute to turn left , an off camber corner- and I felt the suspension compress and the hugely square tyre roll over like it wanted to peel off, we did a great broadside, as they were called back then. Pretty cool.

    Somehow I didn't crash into the parked cars and I peddled off both maniacally laughing at our fortune and my stupidity. But that's 12 yr Olds for you.

    The suspension bike was American import that I think came with a fake engine before I got it. Was very badly made and too heavy. Well ahead of its time though.
    Don't you look at my accountant.

    Well not now but some of those Boardtrack racers were. Or was it the Indians?

    But not since then.

    For some time in the 90's they lead the world in turning recycled woks into profit.
    They also were pretty awesome at turning hydrocarbons into potato potato noises rather than HP

    Years ago, touring in Ireland, had a blowout on my Laverda, two up with luggage. Scary! Lucky it was the rear wheel! Nowadays the tyres are so much better, I haven't met anyone who has suffered one for more than twenty years...

    Yeah, these days is usually only caused by completely ignoring a known problem for an extended period.

    so do cold chisels left laying in the road, as can be seen by the attached picture straight trough the rear tyre of my then CBR900 and then exited out through the rim instant blowout.

    Murphy's law was operating at its most perverse when this happened, not just the cold chisel through the tyre and wheel but it also happen in the worst possible place. The crest of the Auckland harbour bridge at 8.30am on Monday morning. thank goodness for advance rider training that I had done as this allowed me to control the bike with an instantly flat rear tyre. Remained upright so at least i didn't have to add falling off to my collection of woes on that Monday morning.
