370Ad Posted April 18, 2012 Share Posted April 18, 2012 Just received 4 Rays with part worn tyres. The alloys are 99% perfect apart from all 4 have a blue security mark on them. Its a plasticy substance and the only way i can think of removing it is with a flat metal end of a screw driver or the equivalent. This will most definitely mark the alloys so i was wondering if anyone knew a better way?! I have already tried using an old credit card but the mark wont budge. Thanks for any help in advance Cheers, Adam Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted April 18, 2012 Share Posted April 18, 2012 the dots are there to help balance the wheels Quote Link to comment Share on other sites More sharing options...
trackpig Posted April 18, 2012 Share Posted April 18, 2012 The blue dot signifies the lightest (or the heaviest) part of the wheel. The red dot on the tyre does the same thing. In the factory, once the tyre is mounted on the rim, the wheel is rotated inside the tyre until the dots are lined up so the least amount of weights need to be added for balancing. The tyre is then inflated by blowing air down the edge of the tyre bead rather than inflating via the valve. This is done for speed. The wheel/ tyre can then be balanced.

370Ad Posted April 18, 2012 Author Share Posted April 18, 2012 Awesome reply thank you Is it easily removed? Quote Link to comment Share on other sites More sharing options...
trackpig Posted April 18, 2012 Share Posted April 18, 2012 The paint dot is applied on top of the wheel lacquer. I have never tried to remove the paint dot but I would give an alloy wheel cleaner (wonder wheels for example) a go. Quote Link to comment Share on other sites More sharing options...

DannyBoy Posted April 18, 2012 Share Posted April 18, 2012 Bit left-field perhaps, but what about one of the more aggressive detailing clays? They can get rid of tar spots and overspray, so not too much of a stretch surely? DB Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted April 18, 2012 Share Posted April 18, 2012 why get rid of them, you have decent wheels that actually allow for the best kind of weight balancing, and you want to rub it off? Quote Link to comment Share on other sites More sharing options...

bronzee Posted April 19, 2012 Share Posted April 19, 2012 The blue marks will come off with time anyway. Quote Link to comment Share on other sites More sharing options...

Because it looks a bit odd. Lovely clean silver wheel and blue spot! Never seen other wheels with this, I'll give it a go with a few of your ideas and let you know how I got on!

Fat Eddy Posted April 19, 2012 Share Posted April 19, 2012 I always wondered what those blue spots were for! Thanks for the heads up. Quote Link to comment Share on other sites More sharing options...
