Afternoon everyone
The wide 305s look awesome on the Z
I'm a huge fan of whatever the opposite of stretched tires is. The wider tire overlaps the exposed edge of the wheel, providing a good bit of protection. I've rubbed a curb with the rear passenger tire several times during the past few years, but its never even touched the rim; it just leaves an ugly mark on the sidewall, which can easily be cleaned up with some Super VRT dressing
I also fit a 72" wide (read long, narrow box) cellular shade window covering in the Z on the way home
