Odd Front PS4S Tire Wear
Anyone else's PS4S do this on the fronts? Tires were purchased new locally, they're about 6 weeks old and have a couple thousand miles on them.
The rear tires (315/30) don't do this. To me it looks like low pressure, but I've run 32-33 in them since day 1. This weekend I bumped it up to 35, no difference. Any ideas as to a fix?

Looks like driven hard and understeer ? ie scrubbed sidewall?
Checking pressure via DIC or pressure gauge ?

Checking pressure via both, they're all spot on or within 1psi of DIC. Never had a low tire alarm or anything, even with the drop in temp recently. It's just weird, I almost want to say something is wrong with the tires or maybe guess could be the car. BTW car is lowered on eibach and had an alignment at the same time the PS4S were mounted. Nothing looks out of place or odd.

I'm kind of at a loss as to why these tires are doing this.

I did pull the front wheels off last night, treadwear seems even visually at the moment.

Did you replace the bolts and nuts when you did the alignment? I believe you have to replace 8 bolts and nuts at that time.
I used to have to have my car aligned every 2000 miles because I ignored the requirement for new bolts. It didn't make sense to me until I saw a Youtube video about Torque to Yield bolts, and why they need replacing. When I had the dealer align it with the new fasteners, it has stayed aligned for 6000 miles so far. |

It looks like you sometimes have the wheel hard to the left and you go either through a road side rain gutter or up a steep parking lot entrance ramp?
What I'd do is clean the tire real well, let it dry, then get some chalk and draw a heavy line on the shoulder of the tire going from the top of the tread down to where the writing is on the tire. Drive it around some like you normally do and see how far down that line has gotten scrubbed away.

That's a great idea, I have some chalk to give this a shot. Just to make sure it's actually scrubbing itself and not some oddball thing going on. Probably will do both tires, just for kicks.

Marked both fronts (no scrubbing clean) before going to pick up my daughter from daycare so put 100 miles, just normal driving, no issue (see pics).
Will drive more aggressive tomorrow, especially around corners and see the outcome. If no different, I'll drop pressure back down to 32 again and try again.

After a week or so of driving with the chalk on the tires, the chalk was untouched. Dropping them from 35-36 back down to 32psi and see what happens.
https://www.camaro6.com/forums/showthread.php?t=584431 Happen to randomly open this thread and noticed his PS4S front tires have similar sidewall wear. Almost kind of wonder if they were like this from the start and nothing my Z did to them.
