Just picked up a set of km2's 32x11.5x15

What PSI do these run best at on the road? Thanks!

Do the chalk test on the tread and set your pressure based on that.. line across the tread adjust psi until all chalk is worn off.

Put a line of chalk width wise across the tread? Never heard that one before but makes sense.

Chalking the tires will get you the best results. I'd guess you'll wind up around 28-30 psi when you're done. My 33 10.5 KM2's like 29.5.

Chalking - Draw a fat 1" line across all 4 tire treads. Drive straight forward approx 50 feet, do not turn. Stop and look at the chalk line. Gone in the middle and chalk on the outside = over inflated. Chalk in the middle but none on the outside = under inflated. Hairs breath more on the outside than the middle is good since the tires tend to tuck a bit when you're cornering.
