Halfords wheel clamp (Neville's Cross DH1)

This wheel clamp is in robust working condition and can be adjusted to fit snugly around wheels of different diameters and widths. There are limits however, and in the fully extended setting the maximum diameter is around 62cm (24 inches) while maximum tyre width is approximately 21cm (8 inches). I last used it on my old Ford Focus some years ago, but the tyres on my last few cars have been too wide or too big. It would probably be ideal for a typical caravan wheel, but if this is of potential interest to you I strongly suggest checking the size of your wheels first.
