get a basic kit for the tools, then get some refill plugs and patches from local auto parts store. Always have a few extra tubes of rubber cement. If you open one, plan on replacing it when you get back home, they never last long once opened. Put you plugs in a vac sealed bag to help them live a little longer, usually 5 plugs per pack and keep about 5-6 packs. Extra valve stems, valve cores and valve core tool, few razor blades are good to have. Throw everything into a 30 cal ammo can.
I ended up stitching a sidewall and plugging the tire with 32 plugs and it was able to get back to base camp, this guy had two spares and went thru them both on a 6 mile trail. So you can never have too many extra plugs.
a good compressor is a great asset. I keep my co2 hidden from anyone that wants to air up, they can use the compressor. you only get about 16 air-ups on a 10lb co2 depending on what size tire.
my loaner is a viair 400p, then i have a smittybilt 2781 which is crazy fast, and a viair 450 hard mounted as backup which has never been used.
most worth while tool is also an electric impact. i have a nice makita one thats cranks out over 1100 ft/lb. which is handy to have on the trail .
