Hey folks,

I wanted to get some informed opinions on this. Back in 2019 I purchased a Certified Pre-Owned 2012 911 Carerra S (991) through a Canadian dealer. 4 new Pirelli tires were installed at the time. Now, something ALWAYS looked off when I was looking at the rear of the car, it just didn't sit like other 911's of the same era. So, I have it in for a routine service last week (there is no Porsche dealer for about 1800km from me so it's a local tech). He says did you know you have the wrong size tires on the back of your car? I'm like, huh? He said check the door marker and look at the rear tires. They are 295/35/20's, not 295/30/20's like they should be. I spoke to a friend of mine who is the Director of another Porsche Dealer about 3000km away from me and he said the car should definitely have had factory spec tires installed on it if it was a CPO car. He requested I ask for a copy of the CPO work order to see what was done. All the usual stuff of course, and then you get down to the tires and there it is, they knowingly installed the 35's and not the proper 30's on the car. Any advice on how to approach the dealer on this? (I only have 7000km on the car since purchasing it in July 2019, so there is not much wear on the current ones, but I'd certainly prefer to have the proper tires on the car).

Thoughts?

They can't sell a car (let alone a CPO car) with the wrong sized tires.
Have them ship the correct tires to you along with prepaid return labels for the incorrect ones.

Get in touch with the dealer and see if they'll work with you since you have the documentation indicating incorrect tires as part of the CPO process.

You could also use the "speed differential - Speedo reading" route. Here in the US you need to calibrate it when changing sizes. Tell the dealer that it could be a big liability and even illegal.

I'll fight for you mate, you are too nice to each other up there.

Wow, that sucks. Yeah, I would contact the dealer and see what they say.

BTW, document EVERYTHING.
In the past, dealerships have been known to be conservative with the truth..

Might was well see what the dealership says, but you're talking about nearly 2 years later. It wouldn't surprise me if they tell you too much time has passed and you should have noticed it much sooner.

Not worth the hassle after 2 years.

Get a new set of rears and be happy.

BTW drive more will you.

Just ask them, worst thing that can happen is that you buy the tyres by yourself.

Good point from Guards_Red_991.

Valvefloat991

Good idea, except as optimistic as Porsche speedos are, the speedometer is probably MORE accurate with those taller tires.

After two years and admittedly no drivability issues? Let go.

Oh geez, I missed the important 2019 purchase date.
I would move on...

So, paying the significant premium for the 2 year CPO warranty and then have them knowingly deliver it with incorrect tire sizes and call them on it, at any point within that 2 year CPO timeline would not be ok?

Mark Norman

Don't think I will. They knowingly put the wrong size tires on the car. By Porsche's own definition, the car cannot be considered a CPO car unless it's 100% factory spec.

The dealer has realized a mistake has been made and they are going to rectify the situation. - It's hard to drive it more when you live on a island and for more than 7-8 months of the year the car is in storage because there is snow and ice and salt all over the roads. (Oct-April it sits in a heated garage under a cover.)
