Off Road Wheels

Good morning. I have a longboard and want motorized wheels tires (tires are inflatable).

axle diameter is 3 / 8 inches. Does anyone have good site with a group of wheels like that? I checked as mcmastercarr and stuff and can not find a good wheel. the only one I found are like $ 25 each.

Thank you.

You do not know exactly what you need, but you can try the link. Note that you will not find anything good for less than $ 25.
