    First track day yesterday at RAF Woodbridge airfield. I was expecting rain so I kept the all season tires on. But turns out it was a nice sunny day. About 68 degrees. The course has some high speed right hand turns and it shows.

    After about three runs here is what the front left tire looked like.
    That will be the last time I do a track day with all season tires.

    I may have gotten too careless about wheel spin. But I had a blast.

    What were you running for Pressure ? I did the same thing a while ago ran mine in the wet morning session then out can the sun and dried out the track I got slower or the others got faster and the tires took a beating .. :)

    42 up front and 39 in the rear. I was thinking of installing camber bolts because the tire looked like it was worn really close to the sidewall. Did you come across this? My car is completely stock other than the wheels and tires.

    Would tire pressure have an effect on how the tire wares?

    Wearing on the outside edge is very normal for track and autocross. Some tires such as the Direzza ZII come with indicators and you should adjust the tire pressure so that you ARE wearing the outside edge. For autocross, if it's about halfway around the radius of the outside edge, you have them adjusted to a good pressure.

    Sounds like WScottCross answered pretty good there Camber bolts are a option and would help with the wear. But just keep checking your hot tire air pressures and watch the wear indicators on the sidewalls also a tire pyrometer is a good idea if you want to get the most out of the car and tires and keep checking and don't be afraid to adjust pressures till you are happy :)
    Oh and YES tire pressure deffo effects tire wear :) too little outer wear too much and the center tread wears it a balancing act we all play :)
    Based on your pic's you could bump up a lb or two then check again..
