The cheaper pneumatic trolley wheels are very thin 2ply if your willing to pay more you can source 4 ply which last "like they used to"
I have used solid PU trolley wheels and yes they are more a bit more difficult to pull on gravel but generally ok. Purchased via e bay same wheel as sold in dinghy suppliers but cheaper and available in a range of colours. They come with a set of different diameter inserts which I needed to reduce the face depth to ensure the R pin fitted ok.
