I have a set of 18 rays Wheels and Tires from my 04 track Z. They only have 7500 miles on them. The wheels are perfect. No scrapes or scratches. Always washed the wheels back side and front by hand. So they do not have any break dust stains. These wheels are just like new. The tires are cleaned every week with white wall cleaner and once a month protected with Mothers Reflections Tire Care. Even Tread ware on all tires. the front tires have a tread depth of 7/32 Meaning that they are 31% Worn. The rear have a depth of 4/32 52% worn. Tires are mounted on wheels but if you have air pressure sensors you will have to dismount them from your old wheels and install them on these. I kept mine when I switched wheels. Id like to get $1500 for the wheels and tires. That will include shipping.
