A lot depends on the type of wheel you buy. I have 2, one is as described and a bit of a b....r to replace, the other has the wheel in 2 halves held by 2 nuts and washers so changing the tube is a 5, ok 10 minute job. The air inlet has an extension so again is easy to connect to the battery powered compressor I keep in the boot. Mine seem to have phases, one year I can have 3 punctures in a season, other years none, however, I would not change it to a solid tyre because the 'bouncing', ok pneumatic effect helps the mover a lot.
