*We compared a bunch of tires from different manufacturers. The recommended pressures above are an average trend manufactures are suggesting. Especially, if you run a tubeless setup sticking to the proposed numbers will make sure your tire won't blow off the rim in a tricky riding situation. However, less is usually more – more speed, more traction, and more comfort. Please check what your tire sidewall says to make a final decision.
