CHECK YOUR TIRE PRESSURE!

My favorite time to drive a car: just after an oil change or just after setting inflation pressures all-around correctly. Car is SO stable at that point, it nearly drives itself. This "effect" is true in my BMW, Mini and Honda, like autopilot. Pressure drifts from this in a week to 10 days, so I check 'em again. Costco makes it stupid simple. With 5K mile OCI's and tire rotations, all my cars max out their tread life even across the tread. At a little over 50% wear, if there is any uneveness in wear from center to side, indicating over or under inflation, I adjust a pound either way to compensate for the remainder of the tread life so wear is even at the end. Currently running Michelin Pilot Sport 4 on the 335i, Pirelli Cinturato P7 Summer on the Cooper S & Pirelli Cinturato P7C2 Summer on my Accord. Wish I could get the Cinturato C3 and or the Pzero PZ5 in my sizes. Perhaps by the time I'm due for tires I will be able to get those. CHECK YOUR SPARE TIRE INFLATION PREASURE. : ) TIRES: They largely determine the personality of your car!
 
Ah ...Mmmmm.... I don't know how to tell you this, but if you have a 3 to 5 psi pressure buildup, that's to be expected for a passenger car tire. Besides, 38 psi is nowhere near the burst pressure of a tire. Burst pressure for a passenger car tire is well over 100 psi, so I don't understand the freakout.
LoL! Thanks for saying it. I had already been corrected by the internet and auto/tire web pages. I DID mention that many times when I am FULL of Myself about autos (just 50 yrs experience) I wind up getting put in my place. We NEVER really know too much. Always some more to learn. I am open to that. So , THANKS again. I KNOW the burst pressure is way up there. Just did not realize that certain things could actually rise the pressures as much as 3-5 psi. Yup! Put in my place AGAIN. I do not mind. I thank all who share their knowledge. It is a great way to learn. I worked with some older mechanics who COULD not / WOULD not ever admit a mistake or a correction. Those are tough to deal with.
 
Actually correct.
MB is wrong?

Comfort pressures, not longevity, handling, breaking, fuel economy optimisation. Talk to any tyre company tech representative

Perhaps some people might want to prioritise comfort. I'm one of them but my tyres are never underinflated for the load or for the speed. I run comfort pressures around town and highway pressures on longer trips.
