1-3/4" Airwheels, pair

Reals have the most realistic tires you've ever seen in a model airplane wheel. The amount of "squash" is realistic. The "rubber" (it's not, really, it's a vinyl compound) has realistic traction - they're not shiny and slippery plastic. The sizes through 3" are narrow and have lower air drag. They are light weight (for reference to others: 2" -.5 oz.; 3"- 1.25 oz., 4"- 2.5 oz. each). Here's the kicker: They're cheaper than other wheels! Compare the prices! These wheels have a 3.2mm axle hole.
