Hi, I ve fitted TKC80's to my AT, it wasn't easy, did it for the practise before a maroc trip. The biggest problems I had was breaking the bead, on the old tyre and seating the bead on the rear TKC80, I couldn't generate enough pressure on the 12 volt compressor. If I had known it was going to be that tough I would have used alot more soap. Don't let this put you off, they are a very good tyre on/off road and in the wet.
The G clamp tip is good, I took one along just in case, as it happens I didn't get any punctures.
have a good trip.
