TA40ST Occasional Poster Location: Cardiff, South Wales, UK Registered: October 2003	Re: I don't like the way this looks -- Simple issue though Mon, 12 July 2004 18:53 Hi, A UK spec' 1979 TA40 was fitted with 165-13 tyres. They do not have a profile figure in the tyre size. Found this on the subject though.... " The profile of a "standard" tyre is 80, (i.e. 80% of the width of the tread). Some tyres, especially those fitted on older vehicles, don't display the profile number. So you might have a tyre showing "165x14". If the tyre profile number is not printed on the tyre sidewall, you can assume it is a standard tyre, with the profile number 80. " Pumping these figures into a tyre comparator such as: http://www.tyresave.co.uk/tyresize.html and you end up with a difference of +2.36% This will have an effect on your overall gearing and speedo calibration - probabably not enough to worry about though. The extra width may effect other factors of the suspension dynamics though If you want to work out the tyre size/rear axle ratio/speed calculations etc have a look here: http://www.britishv8.org/swaps/design.htm Quite a useful xl spreadsheet Cheers GT [Report message to a moderator]
