This update is a little late but I got the new tires on the Z. I wanted something that would fill the wheel wells without making it look like an off road vehicle. I ended up going with 195/70/14's made by Douglas. They are sold by Wal-Mart and at $40 per tire, they had great reviews, and at only $9 per wheel for mounting and balancing, it was the best deal in town. Plus, they are made in the USA! I have not had a chance to drive it much as I am working on another project but I think its great way to wrap up the project. I had seriously thought about buying some 15 or 16 inch wheels but by the time I added tires my total cost would be anywhere from $800 - $1,000. What do you think?
