WD-40 is first a water dispersant. Although used and touted as a lubricant, it's a crappy lubricant - but it does contain oils and volatile solvents - none of which is recommended for rubber products, and especially tires!
I recommend just about any other lube, a favourite of mine is Tri-Flo, which works great, lasts MUCH longer than WD-40, and comes in a liquid, non-aerosol form, which is perfect for travelling. ONE small bottle of this lasted me round the world, 2 years on the road.
Dish soap as I mentioned can be obtained anywhere for free, and a 35mm film can full will do 2-3 tires.
