If it has 29" wheels, you can also look at 700 tyres besides the 29" tyre models.
How much offroad do you do on the Tero?
If as good as nothing and when you do it's very light, you could simply fit some nice performance road tyres, making sure they are wide enough for the inner rim width of your wheels.
For example, you can now get some Continental GP5000 variants in 35mm and IIRC Pirelli P Zero now do a 40mm variant.
The price range for mixed terrain tyres can vary massively, you could do some 35/40mm Schwalbe Land Cruisers for under £20 per tyre, or spend ~£50 on one Schwalbe G-One Overland!
I've heard good things about the Continental mixed terrain tyres like the Terra models, but yet to try them.
I've got Marathon Supremes (35/40mm) on my gravel which are good for light mixed use, plus a 38mm Marathon Cross on my hybrid that's great for mixed use, but neither model is current these days.
