The best rims I have found are the wolf military ones, they are heavy but seriously solid. If you hit a rock in the road, they would take it.The white 8 spokes are not as solid as the oe rims, they also corrode and look rough in a year or so. The wider tyres (235 upwards) affect the turning circle, so the end stops will need adjusting so you don't foul the radius arms.
I would stick with the 7.50's myself, tough as old boots, cheap, easy to replace. Unless you plan on serious mud plugging (don't with a fully laden LWB) Use a faily road orientated tyre, the fuel economy side and the longer lifespan will be well worth it. there are lots to choose from.
The most effective way of turning petrol into noise without the side-effect of horsepower
