Which tyres fit?

[lazyboy12300]

Sorry for the nooby question, but just got my first 2WD.

So I have my TM2 all built and only need tyres to run it. I have contacted the track which I want to run at (Batley), and was told yellow mini pins all round. So I have looked, but on the front what is the difference between front 2.2 and slim? I am assuming that front 2.2 are for 4wd, am I correct? So will the slim ones with right on the standard team C wheels included?

also, what other wheels fit this hex? As I will be looking for another set and not sure what fits, is it any 12mm hex?

Thanks
Scott
