I have a couple of Blog posts that might help you make a more informed decision on the need for a compressor to carry along.
One raises the question of Do you actually need a compressor
There is also a post with suggestion on how to "Top-Off
" your tire when you need a couple of psi.
Both point out the need to be aware that there are serious safety concerns
if you find you need to add more than 20% air back into one of your tires.
Attempting to inflate a tire that has been run while significantly low on air can result in injury or even death. There is equipment known as "safety cage
" that can help control the results of a tire explosion
