Continental contact Urban. Been running for years on various bikes (cargo, city mtb, tourer) not had a flat, roll fast and are relatively light. Have great grip too. And they can usually be found for a good price!!
Second this! Based on MCamb's recommendation I switched to these from Big Ben Plus and they've been awesome. I run mine tubeless but I assume they're great with tubes too.
