I tried my new tires out yesterday on some easy trails. I aired them down to 25 psi to smooth out the ride and flex over rocks. The funny thing is when I do the chalk test to set the pressure the chalk mark seems to stay the same at all pressures I have tried. I do not have tpms sensors on these wheels. It is weird that the tpms light resets itself when I park the 4runner in the garage and it takes around 10-15 minutes before it senses the tires have no sensors before the light comes on after leaving the garage. The picture of the tire on the rock demonstrates why the 20" wheels and tires had to go for desert use. Rocks like this are common and can cut a P rated tire and you need more sidewall than a 20" wheel can give. I was playing with the atrac. It is a different setup than my 03 had but worked great when turned on when a tire was in the air. So far I have more off road miles on these tires than on road.
