David Sparkes Posted January 12, 2008 Share Posted January 12, 2008 I'm being asked this question, but don't know the answer, so thought I'd pose it here. I don't know why he wants the information. So far I've established that the track is 58.5", and I'd thought to find the offset of a standard wheel, but the Heritage CD Owners / Workshop Manuals only seem to talk about tyre width, not wheel width or offset. I'd guess that the wheel offset is no more than 1", which 'IF CORRECT' would make the drum face to drum face measurement 60.5". Zero offset would make it 58.5" of course. Cheers.

Phil Hancock Posted January 12, 2008 Share Posted January 12, 2008 Standard 90/110 steel rims are 33mm offset inwards so add 66mm to the standard(205/7.50) rim track. Quote Link to comment Share on other sites More sharing options...
David Sparkes Posted January 12, 2008 Author Share Posted January 12, 2008 Thanks Phil, as the Owners Handbook give the Metric Track (centre of tread to centre of tread) as 1486mm, and the wheel inset gives 66mm of that, then the drum face to drum face measurement must be 1420mm. I'll give him that, and the justification. Thanks again. Quote Link to comment Share on other sites More sharing options...
