apologies but need to ask the question.... putting hybrid style tyres on my mtb for in the week???

Another vote for city jets.

I ran with Schwalbe City Jets on my mtb for a fair bit of time, before taking the plunge and buying a road bike.

Almost +1, in that I have an old rigid MTB with City Jets but I put them on after getting the road bike. A good combo and more than capable of handling the 20 mile commute in (almost) all weathers during the winter.

other than it seeming pretty wrong in a kind of ethical way, for cycling to work during the week what tyres are best to put on my MTB?

I don't want to wear the knobbles down, plus speed loss with knobbles on road can be a fair bit

I used City Jets, much better than the more pricey stuff, quick rolling and one puncture per 8 weeks on average (Good for where I rode)
