Pneumatic Wheels!

[Massako]

Hello We are looking for some sort of pneumatic wheels 8 inches in diameter but from other sources than andymark thus being because we are in Canada and it is extremely expensive to ship from us to Canada as well as the exchange rate is really bad so we are looking for some way of using pneumatic wheels from a Canadian retailer. Has anyone had any luck mounting a hex hub mount with non andymark pneumatic wheels by drilling through the hub and mounting them using just regular screws and bolts to mount it to a 72 tooth gear from vex. if not what are some other solutions we could use for using this sort of setup with pneumatic wheels from like home depot.

Thanks
