Did you go with the all seasons?

Which Costco did you purchase them from?

The concern I would have with these tires is that the treadwear rating is over double that of the PS2. That is a relatively hard tire. The goal would be to find a tire that wears out around the same time as it ages out. With a treadwear rating of 540, these tires are going to be hard and look like new when they age out.

My Costco didn't have them when I wanted and I wanted to get them done - so Tire Rack online (had to installer in 2 days) / local installer.

Previous tires were mis-matched front to rear, something 10 years old, sorry I didn't remember more.

The tires are not directional - one side is marked 'outside'. So tread designed toward outside edge the the same on both sides but pointing forward on one side, in reverse on the other.

Here's a higher resolution (if it will upload intact) one side. I'm traveling can try to take better side picture of tire when back in a few days.

Were you able to obtain a set for your car? If so are you planning to put them on the factory wheels or on aftermarket wheels?

This page has a view of the PS AS4 width at 285 & 335 for the C7 (but not on a car): https://www.corvettegarage.com/c7-co...-as3-zp-tires/

But it's always good to see them at the C4 ZR-1 sizes of 275 & 315 on the actual car.

This Saturday the 14th I have my appointment at Costco to have them installed. The front have arrived but the rears have not yet. I will be using my factory stock rims. These will be replacing the 10 year old GY Eagle F1?s. I will be keeping the rears as spares.

...Hope it goes well. It would be great to get your opinion/review/photos comparing your new PS AS4 tires to the Goodyear Eagle F1 tires (assumed GS-D3?) you mentioned are on your ZR-1 currently.
