Hi, does anyone know any suppliers that sell wheels for robotic projects. I need 2 wheels with a diameter of 116mm and roughly 2 inch wide.
If you need a wheel of that specific diameter you might have to fabricate it yourself. Find a rubber tread the right width, perhaps from an old bicycle tire. Cut a disk of wood the right diameter and several rings of wood the same diameter to get the desired width. Glue the rubber tread to the outside diameter.
Has a 4.5 inch (114.3mm) x 2 inch tyre with suitable rims.

I would imagine there are plenty of places, the three that I've bought from include:
- http://www.pololu.com/
- http://www.robotshop.com/store
- http://www.hobbyking.com/hobbyking/store/index.rc
Other places I've bookmarked, but I have not yet bought from include:
thats excellent, thanks guys 
The dimensions you have given are almost exactly the same as RC Rock Crawler tyres, these are generally high performance - i.e. expensive. They are made from soft grippy rubber if thats what your looking for -
They are sold separately from the wheels, the wheels on rc4wd are aluminium beadlocks - great for models, way too expensive for robots. You can get plastic ones for about 10 usd for four.
