ABS light is on, has been on for quite a while, tried putting a new bearing on, still on, new pump, still on, finally went to mazda and they said my tires were too big that was why it was sending the light on. My back tires are 255 45 R18 99W, and my front ones are 225 45 R18 95W. On my car it says that the tires should 225 45 R18 91W. Is mazda right that this light is on because of the sizes of my tires? Looking at all the pics of other people's car who have bigger Aftermarket tires I am wondering if they come across the same problem.
