Hi guys,

thanx for you tips, wot ive done is brought a mountain bike tyre from halfords, which had exactly the same width as my wheels and i cut off the side walls, i then used self tapping(small head) screws which sit alot lower than the tread,so the tread touches the ground and not the screws. for glue i used impact which seems to work well, the traction this has given me now is unbelievable, looking forward to testing at raf waddington on sunday.
