Like new Tires

Michelin ZR rated Sports tires (Omaha)
Four MICHELIN PILOT SPORT high performance tires with 15000 miles driven only. These tires were installed on a 2019 Porsche Panamera 4. I have two 275/40 ZR 20 and two 315/35 ZR 20. Tires are in great shape. Rubbers only and no rims.

I looked up on the internet what brand new tires may have for treads and here is what Michelin stated:

The 275/40R20 Michelin Pilot Sport 4S has a diameter of 28.7″, a width of 10.9″, mounts on a 20″ rim and has 726 revolutions per mile. It weighs 32.5 lbs, has a max load of 2094 lbs, a maximum air pressure of 50 psi, a tread depth of 9.5/32″, and should be used on a rim width of 9-11″.

The 315/35R20 Michelin Pilot Sport 4S has a diameter of 28.7″, a width of 12.6″, mounts on a 20″ rim and has 726 revolutions per mile. It weighs 33 lbs, has a max load of 2337 lbs, a maximum air pressure of 50 psi, a tread depth of 9.5/32″ and should be used on a rim width of 10.5-12.5″.

My 275 tires have at least 5mm tread depth remaining, and the 315 tires has at least 7mm tread depth remaining.

This means the tires still have more than half the tread depth on the front tires (we still have 5mm minimum). Tires have 52% of the as new tires treads.

We also have much more treads on the back tires (we still have at least 7mm). Tires still have 74% of as new tires treads.

I would like to sell the 4 tires at once. Make me best offer.
