Re: Tire puncture advice
The ARB kit (which I carry) is great for straight punctures in the main tread. And, unlike similar kits, the ARB kit uses all steel/cast metal parts for the reaming and insert tools. Many use plastic handles, and - well, they just don't take the punishment they get when dealing with repairing off road tires. The real issue comes in areas where the terrain is sharp fractured rock - like large shale or fractured granite (areas in the north of Mexico for instance). Then the rocks slice the tires, and things become problematic as the only solution is the spare tire. In these areas it is prudent to carry two spares, and get Kevlar reinforced sidewall types, though the additional cost may or may not be justified.
