AT3s imho have a place, just not on something I'd drive every day, in all conditions.
Ye I understand bout the wheel I didn't know thid which is why I was trying to find out, first landrover I've had and never had a lot to do with them so thanks for that info.
Tyres are an individual thing. I'd always get the best affordable tyres for my car, as my children are likely to be in it. This means an A to C wet rating, as nothing less is good enough.
From memory the AT3 doesn't get an EU rating, and if it did its going to be down the bottom of the ratings. As for noise. I know of 3 occasions where they were put on the FL1, and removed again shortly afterwards, due to the noise on the motorway.
Wheels is up to you. But all the steels I've seen for sale aren't hub-centric, so are relying on the studs to keep them on the rims. That's not good enough for me, or most insurance companies for that matter. But it's your car, so you can do whatever you like with it, and have to live with whatever happens to it.
