On my last set of tires, I had Radial Tire Store of Sacramento, put nitro in the tires. we had discussed it half way thru my last set and he said that it really needs to be done when the new tire is installed.
I run 44psi w nitro and the psi fluctuates 1psi (the Q45 has psi senors. In the past it was as much as 4psi different hot and cold.
The trip that is documented in my signature (third link) was my first ever over 30mpg.
I reallt thing the nitro played a role in that.
