tire pressure and blowouts
Last week before leaving on a trip I checked and adjusted all 8 tires. The truck calls for 75 rear, 70 front. It was a warmish day and I'm fiddleing with the DIC ( chev drivers information center) whe...

If you live in an area where the temperature varies wildly from day to day (like 30 degrees, or more), check your tire air pressure the day before the temperature is expected to drop those 30, or more, degrees, and then check again the next day after the temperature has dropped. I have seen a 10 psi drop under those circumstances...so, what is the correct "cold temp" reading?
Tires rarely blow out due to over pressure. All vehicle tires are designed to operate well above the maximum cold pressure shown on the sidewall. The far more common tire failure cause is under inflation.
I agree, the cold setting can change as the ambient temperature changes, but the fact remains that modern tires in good shape are more than capable of handling the typical changes. My take would be the tires should be inflated to the proper pressure at the start of the travel day if temps are fluctuating that widely. Tires rarely need to inflated to the max though, unless the load range used is close to its maximum weight rating.
