I know what a chalk test is (put chalk on tire,roll tire, see how tread pattern looks) but what is the proper way to do the test? What kind of chalk do you use? I would think that the stuff in a bottle for string lines would work. But does it wash off the tire easily? Do you guys roll on paper or just pavement ?

 

Just checked my psi and it was at 50. Tires and wheels where purchased and shipped mounted and balanced from a big name website. Aired down to 30 and ride is much better.

 

I definitely should go check mine, I haven't in a while but I'll tell you I have no trouble in the soft sand on the beach

 

KM2 35 28psi on the road 16-10psi off road 2dr soft top full armor.

 

I run 30 psi in my 35s and they are wearing great and ride smooth.
