Shinko’s aren’t actually tires. They just look like tires. Be careful, especially with spokes. It’s cheaper to buy the more expensive tire once, rather than the faux tire first, then realize it’s junk and then be back to having to buy the better tire.
The bolt pattern on the rear wheel is the same for all bikes from 2003-2017. They just used a thicker bolt after 2005. I would go to ebay, find any narrow-tire wheel from a steel-frame bike, then widen your bolt holes in your 03-05 pulley to accept the bigger hardware. I use a hand drill for this. Easy peasy. And there are a lot of options as you now have 14 model years to choose from.
