Having had a puncture on my 4/4 (tubed tyres); I now carry a spare new tube under my driver’s seat. The spare tubes were supplied by the extremely helpful Longstone Tyres.
I had a spate of punctures when I had tubed wheels on my 4/4, caused by modern tubeless tyres chafing the inner tube. So I bought a set of tubeless wheels from MWS. Not had a problem since.
