Tyre recommendations: towing children on a MTB

My hardtail cannondail trail has been largely relogated/promoted to towing my daughter in her 2 wheel bike trailer.

Currently running the stock WTB ranger 29x2.25s, however they are a bit worn and could do with upgrading. I find them a bit sluggish on the road, but perhaps thats because i ride my road bike more?

80% of my riding is on average/poor tarmac, often towing my daughter as i mentioned, and want something that rolls fast on the road. However i dont want to use slicks as im hoping to do some gravel road / forest track riding when i have some time. Nothing entirely technical/ difficult but will definitely want some off road traction.

Does anyone have any tyre reccomendations that fit the brief? Bonus points if youre in the same boat :slight_smile: ps theyre ‘regular’ tyres with innertubes.

Conti Race Kings are my goto’s for the same application. Nice good volume, low rolling resistance and pretty good at resisting punctures.

Thanks!!
