Default Are my P-Zero's finished?

These are my right and left front tires respectively, my rear tires look relatively good still. Also I have a decent steering wheel wobble now after my last track day...

This is my first year driving on the track and I must have driven 30-40 laps before I learned about adjusting tire pressures. I’ve done 7 more track days since then on these tires targeting 35/36 PSI hot (door sticker says 36/44 cold for street use). Maybe I need to lower my front hot target pressure way more?

Maybe it's time to get a tire thermometer or Michelin’s pilot sport cup 2 track connect’s to help me avoid killing my next set of tires…

Does this wear patter look like overinflation? I'm think I need to replace them before my next track day and rebalancing would not be enough. Thoughts?

Default Are my tires done or good for one more track day?

This is my first year driving on the track and I must have driven 30-40 laps before I learned about needing to adjusting tire pressures. I’ve done 7 more track days since then on these Perrelli P Zero’s. I've been targeting 35/36 PSI hot (door sticker says 36/44 cold for street use).

Maybe it's time to get a tire thermometer or Michelin’s pilot sport cup 2 track connect’s to help me avoid killing my next set of tires…

My rear tires look much better than my front's but went on at the same time. Normally the rear tires wear out first, right? Does this wear pattern look like it was caused by over pressure?

I did develop a steering wobble after my last track day. Maybe I could get my wheels re-balanced or should I just get new tires before my next track day?
