littlebrownbike Posted May 28, 2010 Report Share Posted May 28, 2010 I noticed the other day that the outside of my rear tyres are stepped, not sure how long it's been like this, but not a major problem because it is not making any audible noises. My question is, how does this occur? In theory, this is a bit of a phenomenon to myself. I can understand uneven lateral wear, but not horizontal.

Rich Posted May 28, 2010 Report Share Posted May 28, 2010 I think this is heel and toe wear possibly caused by knackered shocks...I can't quite remember though Link with photos Quote Link to comment Share on other sites More sharing options...
Tony Posted May 28, 2010 Report Share Posted May 28, 2010 Resartched things further since then, the reason is the toe angle, which is adjustable on your car. Quote Link to comment Share on other sites More sharing options...
littlebrownbike Posted May 29, 2010 Author Report Share Posted May 29, 2010 Hi, Those pictures do not show the same wear as my tyre. See attached drawing. Quote Link to comment Share on other sites More sharing options...
Tony Posted May 29, 2010 Report Share Posted May 29, 2010 Assume the toe on the tyre is slightly toed in, then the tyre compresses on the road with a slight lateral twist, the effect adds friction to the leading edge rather than the entire tread confining the wear. Each block of tread is independent and different sizes, this means the scrubbing wear will be different for each size of block, historically the smaller blocks will wear more than the bigger one's.

littlebrownbike Posted May 29, 2010 Author Report Share Posted May 29, 2010 Very strange one. Is it a problem as such? Quote Link to comment Share on other sites More sharing options...
Tony Posted May 29, 2010 Report Share Posted May 29, 2010 Very strange one. Is it a problem as such? No..... The toe position needs to be reset. Quote Link to comment Share on other sites More sharing options...
