New Tyres Needed
I will be needing two new front tyres shortly - I don't do a huge mileage neither do I take it on the motorway often. Any recomendations please? Thank you.

I hope your not referring to any of my bad habits which are enumerable?
Kidding aside, I always change my tyres when they get down to 2.5mm, putting the new tyres on the rear. Must admit I do not swap tyres front to rear.
Now that I'm retired I cover quite a low mileage, so probably would have to change all the tyres anyway due to time expiry. Previously a professional driver of 35 years unblemished, except for getting caught in a 'yellow' box.

People don't look after their tyres anyway. I see people almost daily driving around with a badly under-inflated tyre, which is wrecking the sidewalls, and risking a catastrophic failure. They don't care though! The number of times I've pointed it out to people and they are like 'so what'.
Having had a blowout on the outside lane of a motorway on a front tyre, it was all I could do to keep control of the car. this was a two week old, premium brand tyre by the way with a manufacturing defect.
People also don't realise that tyre rubber hardens with age, resulting in sidewalls starting to crack, and treads losing substantial grip. The industry recommends I think six years as being the maximum safe lifetime of a tyre. If you don't swap your rears to the front, you may only wear the rears down by half in six years, but then are driving around with compromised tyres... you would be increasing risk by transferring those to the front!

/// some 'off-road' tyres have directional patterns so should not be reversed.///
Agreed some do, but these don't.
///evidence for not swapping tyres side to side, and you reply by actually contradicting your own original advice. ///
I said "they can go side to side" as they are not directional, they don't as I don't want to reverse rotation.

Baldric... why do you think that reversing the travelling direction of a non-directional tyre would have any 'bad' effect on it in the slightest?
The tyre is shaped as a toroid, with driving and braking forces transferred through it's side walls from the wheel at the centre to it's tread. Acceleration forces apply a torsional stress via the sidewalls in one rotational direction, and braking forces apply a torsional stress via the sidewalls in the opposite direction. Swap a wheel to the other side of the vehicle, and these stresses are reversed... So what.
