turbogrill Posted April 20 Report Share Posted April 20 Hi, My fronts are very worn on the inner. This is running modest camber with softish suspension, so don't think it's a camber issue. I have heard too much toe out can cause this? Can it be any worn suspension components? 1.6 NA Miata with KYB shocks and lowering springs.

Throoster Posted April 20 Report Share Posted April 20 (edited) Is that outside shoulder worn or just a trick of photography? Looks like a bunch of things going on, including maybe too much toe out, tire pressure is off (low?) and camber may be involved also. Can you tell us what your toe/camber/pressure settings are?

mender Posted April 20 Report Share Posted April 20 If your alignment settings are moderate, check your lower ball joints. 1 Quote Link to comment Share on other sites More sharing options...
MMiskoe Posted April 20 Report Share Posted April 20 What Rooster said. I would bet that this tire was on the "inside" of the track and the other tire was not worn as badly, but still looking pretty beat up. Quote Link to comment Share on other sites More sharing options...

jim161c Posted April 23 Report Share Posted April 23 I had a re71 wear very similar and it was a result of a bent tie rod that created excessive toe out. Quote Link to comment Share on other sites More sharing options...
mender Posted April 23 Report Share Posted April 23 One indication of worn components is alignments specs that wander from one check to another without apparent reason or damage. In other words, if your toe is inconsistent from one test session to the next and nobody curbed the car, start checking for worn parts. I usually try to do a track day prior to a race weekend to tune both myself and the car. Much better to catch issues early. Quote Link to comment Share on other sites More sharing options...
