    i dont agree with his overall comments on yokohama. my teg has parada spec 2 which are simply great in the dry, and very good in the wet. ill be getting some new tyres for the OE wheels soon, and they will be lotus spec advan lts. ive experienced these in wet and dry and was blown away by the grip. some of the tyres fitted as OE by subaru/mitusbishi give great wet grip and almost slick grip in dry.

    bridgestone make some of the best wet weather tyres around, much better than michelin. i would happily buy bridgestone over michelin(unless i had an M3CSL with the michelin cup tyres)

    pirelli p6000, they dont call them ditch finders for fun!
    but pirelli do make some amazing tyres, you just need to look to italian exotica. alot of the lambo's/ferraris etc come with them from factory as there simply isnt anything as good(talking P-zero corsa etc)
    Lotus Elise Sport 160S. its half rover, half something else, but its 100% fun. in the wet, with semis. ooer.

      I will try and get him to come back on this subject and reply to as many comments/queries as poss.

      I personally wouldnt choose the original fitment tyre either to my own rallye,!!!!!!! as I dont think it will offer better performance in certain areas than some new tyres.

      But I understand where he is coming from in that I know how much effort is put into dedicating a tyre to a specific car (millions spent), and that if you want the car to handle as pug intended as per leaving the factory - the OE fit would be one option.

      Also you have to remember this was an overall choice of tyre, an was not intended to be particulary sticky or driven hard - road use tyre remember, not fast road or track.

      Chris - sorry, didnt mean to sound short.

      Stew - Your experiences are based on personal opinions which is great - his are based on testing thousands of tyres on hundreds of cars and working with and for these companies in person developing tyres for mass produced cars. So its an overall picture - not just these work well because they worked well on one car - or this company is great because they do one good tyre etc etc. Its knowledge built up over 8 years of design, development and testing.

        hello everyone, looks like Ive started a good debate here then?
        Just to introduce myself, im the author of the article.

        Well, i'll give a quick response. Obviously, my comments can only be general as I cannot talk directly about the applicability of tyres for the 106. however, I will be aware of the methodology used for tyre selection. Certainly cost is important, but safety is the key which esentially means that all major tyre selection comes down to the big 5 suppliers. And thankfully with tyre choice, Engineering sign off still beats Purchasing as the vehicle chassis (and more specifically the press impression of it) is more important.
        The comment relating to tyre technology is quite right and fitting a 10 year old tyre design could be an issue. My main comments relate to factory fit and replacement within 5 years of production. And if faced by a choice of fitting the originally approved tyre or just a budget tyre, id prefer the original. But I would also look at what was available in the appropriate size from the other manufactures.

        With vehicles in the secondhand market, forums like this can can be useful as you can discuss the brands that you have tried to see if there is a particular tyre which works well. unfortunately, you will find that the higher level brands will not support the smaller sizes, so the choices can become limited, but tht doesn't mean there wont be a good tyre out there. I do know from personal development experience that the latest tyre from a manufacturer does not necessary work better that the old design. sometimes it can be too aggressive for the older chassis, sometimes too 'sporty'.
        You must also remember that I look at a tyre as being the right overall component for the vehicle, not just in one condition.

        Perhaps if there are a list of questions, I could answer them speciifically? I can speak directly to the manufacturers if necessary.

        Hope this helps.

          I wish Jaguar specced up the 18" P-Zero Nero with stiffer side walls as they pinch puncture and delaminate due to potholes and the wheels damage due to this. I can't coment on performance as the ESP has never allowed me to find the edge without intervention... (Dad's car)

          Also "Second hand market" Oi watchit "specialised" is a better term... And most are not running peugeot suspension components and those that are (me) are running tired components which are nowhere near pug factory condition..

              its my job to choose the tyres for our formula student car and there has been a uni in america that has set up a consortium to test tyres at the miliken research center using the calspan machines, so soon i will have 4.7gb of data to process on slick tyres.

              What are the key factors to look into? Have you done any research on slick tyres? At the moment were probably going for Hoosiers most likely or possibly Avons. Can you give a little more detail into how they choose/set up a chassis for a particular tyre or is it just trial and error?

              Probably have more questions soon praise you

              Thanks,
              Rob

                TIRF- calspan tyre research facility
                FSAE TTC- tyre test consortium.

                funnily enough, i was just reading the article in racecar engineering about this by Edward Kasprzak. the university is Buffalo, NY. thats where calspan is located also.
