All Blasters have the same bolt pattern. Stock Blaster wheels are steel. Personally, I wouldn't pay money for steel wheels. For the fronts, Blaster is the same bolt pattern as Banshee and most other Yamaha sport ATVs. For the rear, there's not much else besides Blaster that uses that bolt pattern, so if you want good wheels for the rear, it's aftermarket Blaster wheels or change the rear hubs to Banshee, YFZ450, or something.
