Pyro data is a great start, and some interweb reading will tell you a lot on it. it's a very useful tool, but you must also account for personal driving habits like mentioned above..

If you are overdriving the car and just completely blowing corner entry, the car will understeer and you'll wear the outer shoulders no matter how much camber you have. you'll also have way higher temps on the outer edge which points to more camber needed... BUT.. the problem is caused by driving and not alignment. Sooo you have to take those things into consideration too.

How do you tell if you're driving too hard and causing understeer?
1. are the tires 'singing with happiness' or 'screaming in agony'?
2. once you've turned in and got the weight transferred, begin unwinding the steering wheel. if the car turns less, then you're below the grip limit. if you turn the wheel out and the car continues turning the same arc, you've exceeded the limit of the front tires and are just skidding them across the pavement, eating up rubber and scrubbing speed.

I see that soooooo much with beginner and intermediate drivers. too many people thing "driving harder" equates to "driving faster". throwing a car into the turns and beating on it is not getting the best out of the equipment. it tears things up and makes you slower.

The trick is finding that limit line and getting as close as you can to it without going over. driving the car at 95% vs 105% will yield the same lap times, but driving it at 105% will show itself in high levels of wear on the car- tires, brakes, shocks, wheel bearings, clutches, transmissions, etc get eaten up and the car is very 'lively', while the car driven at 95% looks like it's out on a sunday cruise and consumables last a loooot longer. the guy driving at 105% is also the one most likely to put it in the dirt or the wall and go home on a tow truck.

Obviously I'm not trying to insinuate any driving styles from a single post mentioning outer tire wear, but sharing what I've seen in the track and racing community in the last 20 yrs of playing with cars.

Very insightful, thanks.
