One can take a class on tire sutures?! Cool! At least you know you are taking a risk & have tried to plan accordingly. I took the risk & planned haphazardly! More power to ya if you can keep air in your tires thru some trail repair...
I took my stock Trailblazer off the beaten path yesterday. A mild trail can still be a challenge when you have minimal ground clearance & small street tires.
I know the desire to beef up parts & customize so if you want all that stuff, go for it, absolutely, but if you were tempted because you think your VX perhaps
needs it, in my opinion, for what it
sounds like you are doing, it doesn't. What do I know tho!?
Are you working in AZ for a while or something? Exploring while you are in the area?
