You can get kickass 17in tires for under $100, and most 18in tires are well over $150..
Under most circumstances, that would be true. But cheaper tires in the 18" size was part of my motivation for wanting to upgrade.
In their infinite wisdom, Nissan/Infiniti equipped our cars with 17x7 wheels. The 7" wheel width severely limits the selection of tires we can choose (especially all-seasons) in the 17" size. My stock size is 225/50/17. There aren't that many tires in that size, and most of them are pretty expensive. There also aren't many tires of comparable diameter that will work. 235/45/17 would be a good match, but it's out of spec (requires at least 7.5" width).
The 18" tires I was going to buy were about ~$30-40 cheaper than the 17" tires I currently have on order (backorder )
