Anyone recommend some decent on road tyres for MR?

[damselfly]

Done a bit of searching, but can only find recommendations for off road tyres.
After moving to Lipo/brushless, i've practically worn my stock tyres down.
I'm not interested in off road or racing, but need someting that's suitable for tarmac/car park use.
Also, anyone know the diameter of the stock tyres when new? I don't have a tape measure handy, and my tyres are pretty much done now so even if I measured them the result would be well off.
Tia.
