    You let your 19 month old run out onto the road?

    Awesome parenting there JC.

    another thing they could do is outlaw those skinny little tyres the racers run on....there is no way those things can be safe at all.... maybe ban all tyres that are narrower than 3 inches

    i have no problems with people cycling wherever they want, but i wish all of them would go into single file when they hear a car coming

    same goes for cars that are driving slow, keep to the left and at least gimme a chance to overtake!

    This is one of the most stupid opinions I have ever seen online.

    My club only cycles two-abreast on wide roads, but these are not necessarily roads with a wide hard shoulder. Cycling two-abreast on roads with no hard-shoulder is often safer than cycling single file. The main reason being it saves drivers from overtaking on, what I commonly see, a continuous white line - coming up to a crest or on a bend on the road. The road is wide enough to pass out a two-abreast group of cyclists when it is clear to do so. What's the panic?

    What engineering expertise do you have regarding tyre width that Continental, Vredestein, Dunlop etc don't have?

    Walk through any carpark and check out the car tyres. Illegal thread, cheapest chinese knock offs, 2nd hand German rejects, wrong direction of rotation, incorrect pressures......


    Here is a test of narrow tyres in the most extreme conditions- go on educate yourself a little before making foolish and hysterical statements.

    it doesnt take a genius to know that minimum tyre contact to the road equals minimum grip

    Seriously? Take out a ruler and look at 3 inches on it, be close to impossible to cycle on wheels that thick and with the shape of them you're not actually increasing the road contact hugely without reducing the pressure.

    Also dyou really think engineers would have developed tyres that are unsafe and they'd have made it into mass production. Of course a smaller contact area means less grip but you'll also see a wonderful array of different tyre widths on cars, maybe we should increase tyre widths on all cars to 16 inches, cause bigger contact area is safer and all that.

    but these tyres are clearly designed for racing..... You do know its illegal for a car to drive on racing tyres/slicks dont ya

    It is notl minimum contact, you would understand that if you read the link provided. They are proved to be as wide as necessary and provide safe grip. For any possible scenario.

    How much grip do you believe a bicycle needs? What are you basing your calculation on? Can you post your calculations or even formula? Have you personally experienced an emergency situation while riding a bike and how did your tyres affect the outcome?
    Th link I gave you shows clearly why so called narrow tyres are 100% safe.
    Again ,I'll ask you what qualifies you above the senior engineers at the tyre firms?

    The sheer ignorance regarding basic concepts of safety expressed by some drivers in this thread goes some way to explaining why we all pay huge motor premiums.

    Not that I really want to engage this nonsense of an idea... (And you shouldnt use inches when describing measurements in Ireland. We are a fully metric country)

    Should spacesaver tyres in cars be allowed? Why is it legal to have a completely different size tyre on a car if someone gets a flat?

    I am cycling for years in all conditions, nothing even close to slipping thankfully. Do you realise how wide 3 inches/7.62 cm is? It's like a motorbike wheel! Your opinion is truly ridiculous and if you are the calibre of person advocating changes to cyclists rights I am confident none of your brainless idea would ever be considered.

    Slicks grip is based on the heat generated from driving at high speed, its impossible to generate that heat under normal driving conditions, as such slicks aren't designed for racing they're actually designed for high speeds. Bike wheels heat up quicker due to a smaller mass so they're not designed for racing or high speed.

    what so wrong with inches? is it not an offical measurement is it not?

    you are absolutely correct....space savers are designed to get you off the side of the motorway and to safety. You do realise you are suppose to repair the puncture asap and not drive around on the space saver dont you... did you ever notice a space saver turns white after youve been using it,....this is because of heat build up in the tyre.


    not only slipping but how about breaking? the width of the tyre has an effect on breaking distances

    im well aware of how wide 3 inches is...76.2mm

    so why not make them wider?

    Wouldn't heat up as easily, which would give them less grip, which would make them less safe and increase braking distances.

    As I asked originally why not make car tyres wider to make them safer?

    As a car driver, I despise cyclists.

    As a cyclist in Dublin city centre, I must admit, I hate them even more. The cretins lack so much awareness. When I see dopes cycling with earphones on, I somewhat hope they get run over.Cyclists who cycle in the middle of a cycle lane should be put down. These people never glance back. I have no sympathy for cyclists*, except for myself as I am a supreme cyclist, as well as driver.


    *there are obviously a few good, aware cyclists.

    As someone concerned with safety, upon buying a new car I immediately replace the space saver with a an actual spare tyre. I wouldn't be ever in the position to deal with them.

    I posted in the cycling forum about my experiences trying to get by the Tour of Munster last summer.

    As you can see in the attached thread most of the reactions were less than generous. Some serious a$$holes on that forum. Some levelheaded guys but most were irritated by the fact that i criticised the organisation of the event in any way.

    Ok then, I'll address it here seeing as I don't frequent the Cycling forum too often. I know loads of people that cycle in the TdM, and I can say first hand that most if not all of them are some of the most responsible and safety-aware cyclists in the country. They were not a good example to use against cyclists, and seeing as there are quite a few cyclists from the TdM on the Cycling forum, it was inevitable that they would defend themselves.

    You do know why racing tyres/slicks are illegal on the road, right? Primarily water clearance. A tyre having tread doesn't inherently give it more grip on the road. In dry conditions a slick tyre (a proper slick, not a worn tyre) will provide far enhanced grip and cornering, however in wet conditions a slick tyre will cause a build up of water in front of it, and will aquaplane easier.

    Aquaplaning is a function of many things, speed and tyre width being two of them. Wider tyres aquaplane easier than narrower tyres and at lower speeds. Cars, typically travelling at speeds in excess of 80km/h, are therefore very likely to aquaplane.

    Bicycles, on the other hand, do not routinely go above 35km/h on most roads, and the narrower tyre profile means that they're virtually impossible to aquaplane under normal conditions.

    Therefore the slick -v- non-slick argument is irrelevant when it comes to bicycle tyres.

    The nature of the bicycle in fact makes slick tyres safer on tarmac than wider tyres with a tread
    http://www.sheldonbrown.com/tyres.html#tread

    That link also has a useful table re: aquaplaning. Most skinny tyres run at between 100 and 120 PSI. Meaning that the bicycle needs to be travelling ~170km/h to aquaplane.

    No, I wasnt making that point about Tour of Munster participants, only maybe 1 or 2 responded.

    It was the general attitude on the forum to anyone that made a criticism (a criticism that was confrimed by a few other posters) that surprised me.

    Width of the tyre does not have any bearing on the grip as long as the mass of the vehicle remains the same.

    I believe the tyre rubber compound is the thing that makes the difference. Softer grippier rubber gives the increased grip, not the width of the tyre per se.

    High end tyres for road bikes are made from very grippy rubber and wear out fast (maybe 2000 KM max life). Ordinary car tyres last maybe 20,000 KM.

    I'm a cyclist and I happen to pay lots of money every year for motor tax because I also drive. I have just as much right to use the road while cycling as I do while driving, even if I didn't pay that tax.

    you do know most new cars these days dont even come with a spare wheel....they give you a can of tyre weld and a compressor instead...which is madness in fairness


    it still doesnt make it right though and should be outlawed too
