Default Thread Depth and/or Alignment Issues: To Shave or not to Shave

2011 wrx stock wheels and original OEM tires. I have 25k miles and had to replace my front left tire. Tread depth is now LF:10/32 RF: 8/32. LR:7.5/32 RR: 8/32. Now the car feels unsafe squirrelly at high speeds and continues to noticeably pull to the right at speeds above 55. On top of this, left turns feel like I'm fighting the car much more than before.

What I'm wondering is A: where should my tires be with these depths. And B: should I shave my new tire, and if not should I just get a new alignment?

Thanks for any advice that can be offered, all is appreciated!

you want to match them as closely as possible per axle.

I'd put the 8/32's in the rear, and have the newish one shaved down to 7.5.32nds and throw those in the front.

Thanks for the advice. Is there anything I should look out for when someone is a shaving a tire, or is there a right way and a wrong way to do it? Seems straight forward but anythings possible.

good luck finding somebody to shave yer tire...especially since it is now used

shavers dont like shaving used tires because the blades in the shaver get nicked up from crap stuck in the tread of used tires

ya may have to order a shaved tire from tire rack...they used to shave tires....dunno if they still do

My local tire shop has a subcontractor that will shave for road hazard replacements. The out of wack circumference will heat up fluids at the least. You've already experienced the handling effects. I say better to get tires for a few hundred than a tranny/diff/etc for a bit more, in my uneducated opinion, assuming shave/matching isn't available.
