Hello all - long time member, first time post. Appreciate your patience, I'm certain this has been answered somewhere, but my search came up dry and I'm on a time crunch...

Wheels and Winter Tires for 2019 - 2021 Boxster Spyder and Cayman GT4 models (718 generation).
Front: 8J x 20 ET 57 - Tires: 235/35 R20 92 V XL M+S
Rear: 10J x 20 ET 45 - Tires: 275/30 R20 97 V XL M+S.

Will these 718 wheels/tires fit my 2013 981 "S" (currently shod with 20" Carrera S Wheels and PS4's all around)? Are adjustments (spacers required)? Any details and direction would be much appreciated!

My understanding is 718 wheels are the same dimensions and fit as 981 and are interchangeable. I just bought 718 wheels for my 981. Having said that I wouldn't recommend 20 inch wheels and tires as a winter set if that is your intention. Better 19s or 18s.

Check the back of your manual—there should be a section called “Tire Pressures and Technical Data” just before the index that will give you all the information on the stock wheels. Here’s what my GT4 manual says, for example:




This will give you an idea of what the stock setup is for your car and allow you to compare that against the wheels you’re looking to possibly install.

Thank you gentlemen! I appreciate the quick response. And I was also curious about the idea of 20" winter wheels & tires, but it doesn't snow almost at all where I live, but is often in the teens and 20's making for hard & slick asphalt!
