glasgow Posted April 19, 2016 Share Posted April 19, 2016 2002, SV, original De dion tube. New 13 wheels are "VERY" close to the tube. the clearance between the rear wheel and the tube only allows 3-4 paper sheet thickness (according to Mr Google this is a 0.2mm space).The wheels doesn't touch the tube when the car on the axle stand. But when the car is moving, is it likely that everything stays the same or there may be a very slight movement and I better cut off a few millimeters of the tube. If so, how many mm should I cut.(I do understand the weight balance has to be about an inch away from the inner rim of the wheels)Thank youAhmed Link to comment Share on other sites More sharing options...
ECR Posted April 20, 2016 Share Posted April 20, 2016 Nothing should move, but any flex in the wheel or hub may cause slight contact. I'd knock the corner off the de dion tube with an angle grinder to be sure ... Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted April 20, 2016 Support Team Share Posted April 20, 2016 It's bit disconcerting to have to take an angle grinder to the de-dion but that is what you have to do. Take more off than you think you need to - it's surprising how much a wheel flexes! Link to comment Share on other sites More sharing options...

Support Team Shaun_E Posted April 21, 2016 Support Team Share Posted April 21, 2016 I've never measured the movement but, having taken some material off my de-dion to leave a lot more than the 0.2mm gap above, I still got scratches on the inner rims. I don't know if it's wheel flexing, some movement in the bearings or something else but I would suggest creating a static gap of at least 1mm - maybe 2mm would be safer. This was for Cateham 8 spoke 13" rims. I now use Image 2 piece and not had the issue since. Link to comment Share on other sites More sharing options...

MereCat Posted April 21, 2016 Share Posted April 21, 2016 See wheels / tyres thread for my comments...apologies posted wrongly earlier. Don't know how to link it. In short trim the dedion ears if it's what I suspect it is.... Link to comment Share on other sites More sharing options...
JosephClarke Posted April 22, 2016 Share Posted April 22, 2016 I will check the gap on mine this weekend and measure it, as mine has gone from 14" to 13" wheels. Link to comment Share on other sites More sharing options...
