No, I don't want to modify my RS into a GS. But as I'm living near the dead end of a small road that will be closed completely for a year, and the planned detour will take me over a rough - sometimes muddy - gravel road to be shared with agricultural vehicles, I'm considering putting on a set of tyres which gives me some extra traction and grip. Oh, and I usually drive all year round. If it's safe to walk on the road, I'll drive it. Tips, anyone? Thanks!
