No marks as they where bought brand new

They seem strong enough, I hit a nasty pothole on the road to Kinsale there last week with a full car and the wheels took it fine. It has a set of 55 profile tyres so that helps. Only bad thing is with them being slightly wrong offset with the wobble bolts that came with em, it rubs over undulating roads with a full car other than that they are fine.
They are a super light wheel, you can carry two with wheels not a bother. I guess they are about 4kg's each with tyres, they felt very light anyway.
