This is for on road only.

Not many of us will need new tyres yet but worth a look when we do.

The only thing I'd say is that the 285 and 295 fittings for the Asimettrico (I assume that's the tyre you're looking at) won't work on an RRS for two reasons.
Firstly they aren't strong enough from a load rating perspective (ours are 108/110/112) which will screw your handling and secondly the sidewalls are way thinner than they need to be. You can expect rim damage first pothole or kerb you come across. Your RRS will feel anything but sporty on tyres that move around like I'd expect those to.
Also, because they are outside our recommended 2.5% tyre diameter limit, your gearing, speedo and everything linked to that will be out of kilter.
The 305s won't fit on the 9.5J rims and even if you did, you'd need spacers and I'd suggest seeing the other thread on that one.

No it is the same 275/40 as the conti tyre. Same load rating as well.

The P Zero SUV.

Ah yes, found it thanks.

If this is right, that is nearly 100 quid less than the Conti. And two db quieter, which will be good.

I wonder what the cost will be?
