Dave Moss Unsprung: Tire Wear | OnTheThrottle.com
Of course those of who who have been racing for a while already know it's not quite as simple as matching your tire up to a picture and instantly having your problem solved. Sometimes there are many complicating factors in tire wear that you can only discover by experimenting and using deductive reasoning to narrow down the problem. Before anything else, get your sag set and make sure you have the correct springs for your weight. If you don't do that first, you're wasting your time, and no twiddling of the knobs will make a bit of difference. Once you've got your sag set with the right springs, then get your damping dialed in for an even response on rebound both front & rear. After that, now you're in the area where you can use this type of information to diagnose a tire wear issue. That still doesn't mean you can match your tire up to a picture and know what your problem is, but it can help guide you in the right direction at least.
