I highly recommend them, I have BIG air horns on my truck and they keep up very well. (We are talking real railroad diesel locomotive horns, I built the system into the truck, including air hose connect for airing mine and anyone else’s tires). Rick

Are you saying that you semi-permanently mounted the VIAIR to the truck?

It yes, photos, please.

I will put it all in my made motorhome tirepressure calculator.

But I am suprised bu the relatively low extra maxload the 123 loadindex tire gives at 80 psi then your P-tires LI 116 AT 35 psi.

Then your old T speedrated and new R speedrated.
What is max technical carspeed of your car?
Here in the Netherlands tyres must have same or more max speed then max technical carspeed.
I assume that is also law in America.
