Tire psi in 100+ degree weather??

[Waterloo]

I would set it a tad less, but only do that on a cold tire, letting the air out. Say 90 on the drives, 100 on the steers, there about. Some of these tire manufacturers are saying running a bit lower psi is better in the long run for the longevity of the tire. I have read that in several publications from the tire "engineers" at Michelin and I think Continental. If true or not, I don't know.

Others will chime in.
