Epicuser - I've only had them on for less than 24 hours, so I cannot comment on fuel economy. I can't imagine it making a massive difference. On the road, the handling is no different from the Marshal Road Ventures on the 225/55/17s that I had on before... if not slightly better. Reference noise, they have an appalling dB score, but to be honest, I haven't noticed anything... that said, it's a Land Rover... not a car I bought for refinements and luxury, so there are probably numerous rattles and grumbles I don't even notice anymore.
Kizzeh - No... it's probably a combination of light factors and the fact they are brand new.
