That's good because any decent toolbox has a set of 1/4", 3/8", and 1/2" metric and SAE sockets. Hmmmm... I just realized that those socket sizes are in SAE units, and not in metric units. Do the 4-sided openings in European sockets conform to the same standard 1/4", 3/8", and 1/2" sizes we use in America? Or do the Europeans use a metric sized drive square? > It's not a torque wrench - its just a wrench with a telescopic handle > that is at least twice as long as that which normally comes with the car > kit.

We all have used a pipe in times of need, to extend our leverage. Most of us have pretty long "breaker bars" though, which is what I would use if I needed the torque to remove a bolt. >> It must be a clever internal mechanism that calculates the torque correctly >> when you can change the distance along the lever! > > It you added an extension tube to the end of a normal click type torque > wrench to make the handle twice as long and you applied your pressure to > the end this extension wouldn't the torque wrench still click at the > correct torque? It would as long as the only point of that loosely fitting extension tube touching the torque wrench were at the place that you would have put your hand on the torque wrench. I guess if you put a tightly fitting extension tube over the torque wrench of a length that doubles the torque wrench length, then you'd get a "reading" of (half? double?) on the torque wrench. Let me think about that.... (would it be double or half?). Upon a few moments of circumspection, I'm not sure, but I think you'd get a reading that is half what it actually is?????? |

It's hard to tell if you're serious or if you're just trolling because I already said multiple times in this thread that a palpable feathering occurs at around 4K miles, which is normal for some vehicles driven under certain conditions, even when tires are properly inflated and suspensions are properly aligned. > What on earth is the point in moving them around so you have > to replace all four at once?! While readjusting the assembly static balance and tire pressure (if necessary) is more of a comfort than safety issue, there's added safety in inspecting the tires closely periodically to look for damage and to pluck out objects, where invariably between 50 and 100 pebbles and shards are removed from each tire in each rotation cycle. So that's roughly about 50x4x4 objects removed every year from your tires. How many of those 800 objects would eventually cause a blowout? Maybe fewer than 1/10th of a percent, but this tiny shard I removed yesterday certainly had a slow-leak potential: http://wetakepic.com/images/2018/02/18/splinter3.jpg |

Yep, standard 1/4, 3/8 and 1/2 square drives which can be used with both imperial and metric hex/12 point sockets. > > It would as long as the only point of that loosely fitting extension tube > touching the torque wrench were at the place that you would have put your > hand on the torque wrench. > > I guess if you put a tightly fitting extension tube over the torque wrench > of a length that doubles the torque wrench length, then you'd get a > "reading" of (half? double?) on the torque wrench. > > Let me think about that....

In my experience of 40 years of driving all my punctures have been made by objects long enough to go straight through the tyre the moment I drove over it. By your logic if 10% of the shards could result in a puncture would all of us that don't preform this task expect around one puncture per month? -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

That's strange that Europeans use a half-metric half-what-you-call-Imperial standard of units. To us, Imperial is a strange word, where it often means Imperial Japan or Imperial British (meaning before WWII in our vernacular), but we never use the word "imperial" in terms of measurement units (at least I don't). I have seen "imperial gallons" where I have to ask what they are, since we just have gallons and liters and nothing else (similarly with regular tons and long tons I guess). I guess, since the US is anything but imperial, that the term must be so old as to predate the SAE, and to relate to Imperial British units? >> Let me think about that....

OK. I'm confused because I have a dial-type wrench which has a pin which certainly is to prevent you from putting force at any other point for this reason alone.... |

I can't stake my mortgage on the percentage but I did say one tenth of one percent, and I did easily count over fifty objects per tire, which is about 800 objects per year, which let's just call 1000 objects in a year for simplicity of math per set of four tires. One tenth of one percent of that number is 1 slow leak a year due to shards, which I agree might be too much. How many slow leaks have you had over the years? If it's a slow-or-fast leak once every ten years due to an object penetrating the carcass, then the percentage is roughly about one-hundredth of one percent. How often do you get a leak (slow or fast) in your tires due to object penetration? I think the (slow or fast) leak due to an object penetrating the carcass percentage is somewhere in between the one tenth of one percent and one hundredth of one percent, don't you think? Statistically speaking, I get your drift that it isn't worth removing shards from a tire just to prevent a slow leak every couple of years, but, anecdotally, what do you think this shard would have done, over time? http://wetakepic.com/images/2018/02/18/splinter3.jpg |

Say it takes 50 pounds of force at the end of the handle to loosen a nut. Take a wrench with a 4 foot handle. It will take 25 pounds of force at the end of the that one's handle to loosen the same nut. That's why cheater pipes work. |
