Thanks for the reply. I've got a couple of options now. I have been reliably informed that Adam Skeldings A1 setup from the Durango site works well on carpet (by Adam), and fortunately for me, I have what I need to apply it to my Truck..
I'll let you know how I get on with it.. I haven't cut the inner and outer rows of spikes on the front tyres yet, as they are worn a bit and once done, there's no turning back.... But will be taking side cutters with me and will have no hesitation in choping them up if need be..
