Alignment Question
I have a 2010 base with approximately 22,400 miles. The tires, original GY runflats (fronts) are wearing on the outer edges. ( All tires inflated to 30 psi). The rears look OUTSTANDING. When I replace the tires and get the car aligned to PFADT pure street specs, should I just get the fronts aligned and leave the rear setting as is?
Thanks.
Thanks.

Align all the tires Pfadt street for a DD.
The OEM is a semi street/semi track alignment, and unless you are pushing the car hard, will not need the OEM alignment or more aggressive track alignment.
Hence the aggressive alignment is for when you are pushing the car hard in corners, and putting enough force on the outside of the tires to wear them as well (for a even wear across the entire treads).

Your front tires are wearing on their outside corners? That's quite unusual. Most have severe wear on their inside front corners -- frequently so deep it exposes the steel cord wires. Wear on the inside front corners like this is very often unseen with the car on the ground, but is readily seen when the car is on a hoist.

It depends. It's not that the dealer can't do the Pfadt settings but they will typically say they got it perfect. And what they mean is, per the GM setting RANGE, they got it perfect WITHIN the range. Frankly, that's not good enough. I do have a dealer tech who, if I went to him w. the specs I wanted, he would either say, I'll do it, or, no that would take too much time for what I can charge.
In which case, I'd start asking at Excelsior in Escondido who they would recommend (don't think they do it themselves) or call and talk with Larry Hofer at The Corvette Shop. He might recommend Clarence Brown Alignment on Armour St. which is nearby Hofer.
And just remember that an alignment may not be a once-a-set-of-tires type of thing.
