Re: Chalk method for tire pressure?

How wide are they?
Rims definately are too narrow. I do the chalk test on ALL my vehicles, so does my son. We are seeing 10k miles more out of a set of tires. SUVs and trucks typically need to run less rear pressure than front because of the weight bias of the vehicle. My wife's F150 crew cab FX4 has 34x12.50x17 AT4 (rugged terrain) tires. We run 30psi in the front and 26psi in the rear. My Nissan Xterra has 245/75-16 Falken Wildpeak AT3 tires on it. Running 31 in the front and 27 in the rear. Here are those tires with 49k on them right now, rotated about every 7500 miles.
