Tire Pressure Question
I noticed my tires seem to be wearing more in the middle indicating their overinflated. I keep them inflated around 34-35 lbs but once they build up pressure, on a hot day driving on the highway, this pressure will increase to 38-40 lbs.
My question is, what do you guys have them set at? Please specify if this is at startup when tires are low on pressure or if its after driving.

I use a dial type like you're referring to. I've always inflated them to 35 but since I noticed more treadwear in the center of the tire, I began to think this might be too high.

I agree with TreeFiddyZee. Check your measuring instrument against a known good-quality device. It’s possible your instrument is not calibrated properly.
Better quality instruments have calibration settings.

I think its calibrated correctly since its exactly as Treefiddy is describing. I got them set at 35 cold, but the heat in the summer and driving on the highway, I see it creep up to 40-41. I was thinking about dropping them down to 33 or so cold in order to compensate for the heat.

Whatever you do, do n't underinflate them, that's just asking for trouble.

Yup.
Most drivers are lazy about maintaining proper tire pressure. They ignore this, and often run at low pressures. As DavesZ#3 mentions, this is a very bad thing.
But then again, some people decide to maintain the pressure. They read the maximum pressure on the tire’s sidewall (maybe something like 50 psi), and jack-up the psi to that value.
