As far as I know Porsche didn't offer all season tires as OE on any sports car probably for marketing reasons but also for warranty reasons. The Porsche specific summer tires it offers are marked N2 with supposedly different sidewall construction, and price.

If you made a side deal with a salesman then had you put it in writing the dealership should be obligated to honor it. I'd still question whether Porsche would void any tire related warranty.

It sounds like you were fooled by the salesman, shame on the dealer for not taking the hit.

Having said all that, I also use AS Michelins on these cars in the late fall or early spring seasons. You give up nothing in real life grip and can drive the car in 20 degrees where summer tires would feel like slick hockey pucks.

I wasn't aware that Yokos were OE offered on these cars. My 2025 Boxster GTS came with P Zeros, my 2023 Boxster S with Michelins.

I'm kind of surprised nobody wants your tires, I'd ask $400 and see what happens.

I run Toyo Proxes Sport AS year-round here in western Oregon. I can avoid the few days we get snow or ice, and the tires work great in all other conditions.

 

Great answer, thanks. Good advice, too. And you have that in writing... which I did not have with the Porsche salesman!

 

Welcome to the forum. I'm not surprised that your SA is no longer working there as Porsche does not equip sportscars with AS tires from the factory. They produce a list of Porsche approved tires and all are either UHP summer tires or winter tires. The Porsche approved tires have the designation Nx, where x is the version number of that tire model.

The restrictions on accessing classifieds are there to limit the damage that scammers do. Please don't try to get around it by mentioning items for sale in the general forum.

Thanks for the note. If I was under the impression that my salesman was fully informed and being totally forthcoming with me. It ended up not being the case. But at the end of the day, it's on me for not doing the homework when buying my first Porsche.

As for your subsequent comment - I'm happy to remove immediately my initial post if you say so. There was never a sense that I was trying to bypass rules it by mentioning these in the general forum. I'm new to posting on the forum and was simply building up my presence by posting so I would be eligible to post in the classifieds.

 

Not the first nor the last time a sales person confidently gave an incorrect answer instead of giving the correct one of finding out the correct one before answering.

As for "holding onto your warranty", in the US, you can have anyone install tires, change your oil, etc. without affecting your warranty so long as they didn't mess up the task. One of my local dealers does happen to be very competitive on tire installation costs when compared to Costco or Discount Tires though.

 

I live in the northeast US and intend to drive my Boxster as a "cruiser" more than anything else and would have preferred AS tires as an OEM option, but was told that wasn't the case, which comports with everything I'm reading here.
