I'm confused now. Are you thinking of getting a second set of lighter wheels for the LHT and foregoing the Gunnar altogether? I thought the point of your question was to figure out whether you could use your LHT wheels (with skinnier tires) on the Gunnar, but perhaps I have that wrong.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
