Ran by Crest Cadillac this morning at 7 AM for a suspension alignment for my 2008 Cadillac STS-V. Alignment is something that does not HAVE to be done at the dealer, but Crest makes it easy to get in and out and on with my day.
I went in with the expectation that the current alignment was okay, but after my recent tire issue I wanted to be sure. The alignment report shows the car as a STS base model, but Cadillac only issued one alignment spec for the STS.
I scheduled ahead of time online with Crest, and they emailed and called to confirm. I asked for a 7 am start, and my Service Advisor Gene met me as soon as the door opened. It took just over an hour for the alignment, so I enjoyed the Customer Lounge, and wandered out and looked at the new Cadillacs.
Based on the inner-edge wear on the original Pirellis I thought if anything was off in the alignment it would be the camber. The alignment results show that the camber was in spec, but the Toe-In was off slightly left front and right rear. Normally one might expect a saw-tooth wear pattern across the tread if the toe-in is off.
I have read other owners experienced a similar wear pattern with the Pirelli runflats, so I am not certain what to conclude. I’ll keep an eye on the wear pattern for the new tires and we’ll see. In the mean time, I’ll keep enjoying the STS-V.
