The active link is in the first post and under the first sentence. The fuzzy example is just that.

A few words of caution.
-- this will provide the minimum recommended cold tire pressure, not the optimal pressure.
-- for the purposes of tire pressure, axle weight is 2 times the weight of the higher weight of the right or left wheel positions. This is critical because left and right wheel positions can be significantly different.
-- i personally would never inflate a tire to 85 psi as that is the lowest pressure recommended by Michelin.
-- always favor a higher pressure when in doubt up to the maximum allowed pressure.
Remember that under inflated tires run hotter at speed than properly or over inflated (up to the tire's maximum allowed pressure) tires. Under inflated steer axle tires are likely the primary contributor to blow outs.
