    No legal requirement no, but if you hit one, even if it's the pedestrian's fault, you are still going to end up in a lot of trouble for it unless you have a dashboard camera and it doesn't show you putting your foot down to beat the pedestrian to the crossing.

    In any case, whether you slow down, maintain speed or speed up, you really don't want to be distracted for a second or so checking your speedo because of the bloody camera.

    In which case it is probably wise to ensure that you are not driving anywhere close to the speed limit in the first place. It takes microseconds to glance at your speedometer.

    Any answer Flyboy?

    Well....excuse me for not spending the entire night on the forum. Believe it or not, I did have more important things to be getting on with. :wall:

    Because

    A) it's perfectly legal to have tyres of a different profile on the front axle providing they match

    B) both tyres have in excess of 6mm of tread.

    If you'd like to donate to the £150 that two tyres would cost, feel free.

    A cheque is on its way. :D

    Have you notified your insurance company that your car has been modified, that it uses tyres other than those recommended by the manufacturer.
    Your second comment is a bit pathetic, if you cannot afford to maintain your car, then buy something cheaper or walk.

    So any car that's had new tyre's has been modified?

    Manufacturers tend to recommend replacing with exact brand/model, so effectively by manufacturers specs we're all driving modified cars.... And where do we stop? manufacturers also recommend their own replacement brake pads/discs, how many people do that?

    Interestingly we're pretty much ALL driving on inferior quality brakes and inferior quality tyre's (according to the manufacturer specs) and the insurance company is "ok" with that... But as soon as you put a sports exhaust on your motor, they jump on you. Doesn't seem right somehow when you look at it that way...

    It's all subjective isn't it?

    The important word being recommended.
    When approaching a zebra crossing you should always slow down slightly, and be prepared to stop if someone wishes to cross
    Are you saying that if you were approaching a crossing and it was perfectly obvious that there was no one on, or close to the crossing, then you would still slow down?
    This is not what the highway code states, and is confirmed by the UK driving test report sheet.
    24 Pedestrian Crossings
    You should be able to recognise the different types of pedestrian
    crossing and show courtesy and consideration towards pedestrians.
    At all crossings you should slow down and stop if there is anyone on
    the crossing
    . At zebra crossings you should slow down and be
    prepared to stop if there is anyone waiting to cross. Give way to any
    pedestrians on a pelican crossing when the amber lights are
    flashing. You should give way to cyclists as well as pedestrians on
    a toucan crossing and act correctly at puffin crossings.

    Then again that kind of brings us back to the OP. They were "concerned" that they might not be concentrating enough when passing the crossing, if they had to look at their speedometer. If there were pedestrians about to cross, he should be slowing down anyway, thus shouldn't be anywhere near the speed limit, ergo he shouldn't be looking at his speedometer to distract him from the crossing. If the OP was to look at his speedometer regularly, as he should be doing, he should be aware of his speed anyway. Thereby not having to change his driving behaviour to comply with the safety camera.

    Lots of people think that, but it's wrong.

    For starters you have to refocus your eyes, twice, and this is not instant.

    One could say that because of "re-focusing" issues, they shouldn't look at their speedometer at all.

    Sorry, but I don't buy that. If ones eye sight is that poor, they shouldn't be driving.

    That is actually an argument I have heard seriously. The theory goes that if you go back to the good old days where everywhere except for built up areas were "derestricted" rather than NSL, drivers were required to select an appropriate speed for the conditions and surroundings, and this would be done on judgement and feel rather than compliance with an arbitrary number.

    As a result of this there isn't actually any need to look at the speedo and indeed a competent driver would be able to drive perfectly safely without one (which is why race cars often don't have them).

    Of course, it's not like that these days and now the driver has to concentrate on two separate speeds, one is the appropriate safe speed for the conditions which is still based on judgement and feel and the other is the speed limit which may or may not be a close approximation of the appropriate safe speed.

    In order to ensure you are below the limit it is necessary to periodically check the speedo and compare that number to the one on the sign. This is a different mental process to that needed to select an appropriate safe speed based and thus is an unwelcome distraction.

    The counter argument is, of course, that built up areas have always had a 30 limit. This is correct but most drivers are capable of hitting roughly 30 anyway, but if they drifted a few mph over, yet were otherwise driving fine (which would include slowing down on the approach to a crossing!), it is unlikely that an old fashioned copper would actually do anything, at worst maybe pull them over for a ticking off. So it's still

    The camera, OTOH, is a device, you exceed a specified number, click click, 60 quid please. Many drivers tend to get a bit paranoid around them. Many others now believe that they just need to stick to the limit to be safe and put no further thought into it. Both of these will be checking their speedo as they approach and for that crucial moment will not be looking at the road, or at the pavement either side of the crossing.
    Sorry, but I don't buy that. If ones eye sight is that poor, they shouldn't be driving.

    This is for normal eyes. I don't know if it's common for the focus time of the eyes to degrade over the years. You don't notice the refocus time as the brain is actually very very good at processing the image from the eyes (same reason you almost never notice the eye's blind spot) however the brain cannot make the eye show detail that isn't there, only the magical computers on CSI can do that.

    Is the width of the tyre seriously going to affect the revolutions ... lol the profile depending on the wheels fitted would affect the speedo, but not the width!

    Wrong, the profile is a ratio of the width, a 165/70R13 would have a profile of 115.5mm, a 195/70R13 would have a profile of 136.5mm. Difference of 21mm multiplied by 2 = 42mm difference in total diameter

    Detailed explanation at http://www.jettyres.co.uk/tyre-tips/tyre-markings/

    Plenty of on line calculators, speedo would be around 1 mile per hour slow at 30mph

    So im not wrong then, you just justified my statement!!!
