Rear Tire Pressure Survey

[Lee]

In the past, I'd air up or down on the road one or two pounds depending on road surface, temperature, and my feeling on the bike, but I realized the other day that with this big beast, I hardly ever feel the need to make significant changes while riding, and to be honest, as I just ordered another heavy weight (2-ply) Metzler for the rear, I have to admit, I'm probably not the sensitive, tuned-in rider I was or would like to be. (Or, the tires and adaptive suspension have become really good).

I'm not good enough to feel a 1 psi change in pressure and not good enough to feel 2 psi.
I have the 2 psi rule hoping to extend tire wear.
With the TPM measuring at 20 C, I think that's 68 F, it's surprising how the TPM tire pressure rarely changes on a trip.
I saw little change in the TPM reading with temps ranging from 41 to 107.

A few miles from the house after the TPM readings have settled out I check the display and ask Debbie to check her display. After that I try to keep the display the same. I rarely have to change tire pressure on a trip with this method.

The gauge I use at home reads the same as our TPM readings if the temp is close to 68F. The pencil gauge I use on trips surprisingly reads the same as my home gauge.
I carry the pencil gauge on trips just in case I doubt the TPM reading.
I used to carry digital gauges on trips but they seem to give bad readings after a few years.
