Strong robot wheels

Hey guys,

I'm looking to buy some wheels for a robot I'm making. It's going to be fairly heavy (around 30kg), and I need some strong and high-quality wheels.

Do you know any decent companies that focus on wheels, in the UK?

Not offhand, but I suggest unless its indoor only you're best with pneumatic tyres once up to that sort of weight, take a lot of strain off the wheel bearings. Yes you will need proper bearings too I think (Simply Bearings ltd?).

robot marketplace. googly them. They have fantastic wheels.
