You can use a servo horn to mount any wheels. A dab of hot glue on the horn will hold the wheel in position.

thanks, I was actually thinking about that but first I wanted to doble check if there were original wheels.

Check out RobotShop.com they always seem to have different wheels available. servo mount and hub mount.

Hey guys, shameless plug but Solarbotics sells those type of wheels they are 2-5/8" in diameter.

thanks, skater_j10 and Lumpy. I really found useful both of your recommendations. I think I will use:

from www.robotshop.com

No worries.

My normal shopping sites are:

Robotshop (Canada) Sparkfun Solarbotics E-Bay

Don't forget pololu.com they have cheap parts too

I've looked at Pololu but i think the international shipping rates always deterred me from ordering.

@Diego, Unfortunately the tamiya wheels you chose don't have a splined hub for a servo but rather a 'D' shaft for DC gear motors. You may have a hard time interfacing the 2 together, unless you use something like epoxy putty but even then the wheels might not spin true. The only wheels on the market (that I'm aware of) that are designed for continuous rotation servos are from Pololu, EZ-Robot, & Solarbotics. (Robotshop is a reseller of all 3).

thank you all for your suggestions, taking in consideration the problem with the Tamiya Wheels I think I will choose the Pololu Wheel.

Hello again Diego, unfortunately those have the D style hub as well so you'll run into the same issue, you'll want some wheels from This section

Turns out lynx motion and Hi tec have some available too, never knew.

Also look at ServoCity. They have a good selection of wheels and hubs. This is my favorite site of all.
