    Pirellis on my CGTS

    I have original P-Zeros on my 2016 CGTS. Currently just over 12k miles. I plan to switch to Michellins when the time comes. I dont track and the tires still have good thread on it. The wheels were powder coated.

    It rides seems to be a bit unstable at high speeds. Should I get the tires re-balanced and get an alignment done or is it almost time to just do it together with new Michelins.

    Also for all the Bay Area owners who switched to Michellin Pilot 4S. Was it a big different in comfort and quietness with our lousy roads here?

    Re: Pirellis on my CGTS

    Hey I have a 2016 CGTS also, in LA. I was at the wear bars on my rears at 9,000 miles. The fronts were fine. I changed all four to Michelin PSS (4S was not yet available but PSS is very similar) and found a dramatic improvement in comfort and confident handling. My pirelli rears had been tramlining and handling had degraded. I bet you need new rears now. You could just replace the rears with pirellis but if budget is not an issue you will probably notice a huge improvement with four Michelins. Definitely get an alignment — from a shop with Porsche knowledge.
    I had -1.4 degrees of negative camber added in the fronts and -2.0 in the rear and that also improves handling dramatically. Others have different alignment advice but for an aggressive street setting I love my alignment.

    I'm in the same situation on my 2015 CS with about 12,000 miles on the clock. The rears outside 1/3 is shot just a small amount of tread left with the inside edge with plenty. Fronts are wearing evenly and have tread left. From what I have been reading my rear camber is not where it needs to be. I've had the Michelins on my 996 Turbo and they transformed the car. When we finally dry out up here I'm replacing all four with the Pilot 4S's. A more aggressive alignment as well. Celinapayson thanks for the set up specs on yours. I've got the X-73 and PtV on mine and need the right alignment for some aggressive street driving.Hopefully better wear as well. Not tracking the car as of yet. We have some awesome roads up here that need to be explored more. BTW what do you guys get charges for alignments down there? I'm new to my area up here and I've found some indy shops off of the PCA Oregon site and I'm going to give them a call.

    I think for a Porsche expert independent shop the norm here is about $150.

    Thanks folks for the input... looks like I should just replace all four now with Michellins.

    The local stealership charges close to 500 for mounting, balancing and alignment. I'll check into the indy shops close by.

    Re: Pirellis on my CGTS

    I agree with your decision (to replace all tires now then get alignment). You won't be disappointed!

    As for the dealer vs. indy, my dealer's rates were very reasonable so I went that route. But remind the tech to use the black painted wheel balance weights if your wheels are platinum or black, otherwise the silver ones will be noticeably visible. I think most dealers stock both colors.

    I also switched from P-Zero to PS4S on my 2016 GTS and am very happy with the switch. The P-Zeros were worn to cord on rear inside at 10,000 miles and I have 12000 miles on PS4S with still many miles to go. The Pilots are better in every way, especially handling.

    Re: Pirellis on my CGTS

    I recently bought a 2016 C GTS CPO that the dealer put on new P-Zeros and could not get them to change them out. Previously I had a 987 Boxster S with Pilot Sport Cup 2 tires that I loved (camber and exhaust had been changed) . The GTS felt much less stable here on Highway 1 so I switched to Michelin 4S and now feel quite confident in this car. I was able to sell the almost new P-Zeros for $500 so the pain was reduced. I highly suggest getting the tires balanced on the Hunter machines. I will be looking to tinker with the camber next. If you have a car that you're going to drive hard, get the tires that allow you to be confident now, it's not worth waiting in my opinion.
