The Dealer Recommended me 35 psi. But the ride quality deteriorated. Every single bump makes the car feel so rough. every single road imperfection can be felt in a negative fashion. Also, the car never made me feel like a very confident driver at around 35 - 3 psi. i bought it down to 32 - 33 psi. Now the ride quality is much better, Car feels more planted on the road and handles quite precise. I personally am much happier with 32-33 psi.

never blew out a tire from hitting a pot hole/curb (and i have hit some nasty pot holes in Lowell MA, also 1/2 of down town is all cobble stones)
never cracked/bent a rim.
never had a set of tires wear out too quickly
every one thinks/says that u will blow out a tire if u hit a pothole when ur inflated near the max. and every time i ask people, do you know any one that has had that happen, they all say no...

That's funny. My friend told me the same thing, hit a pothole and ended up in a ditch.

that sucks, glad ur ok.
but that can't be related to high psi.
im talking about people saying that the reasons for those kinds of blow outs are related to high psi.
in ur situation, i bet a high psi tire would have blown. but ur situation also proves that a low/normal psi tire will blow, so the blow out was not caused by high psi.
your story is the classic case, "i know so and so had a blow out cuz they hit a pot hole"
thats where the story usually ends cuz no one can verify if the blown tire had high psi. most people just assume it did, so every tire monkey says "YOU MUST RUN 30 - 35 PSI OR YOU WILL HAVE A BLOW OUT" and none of them can trace a blow out back to high psi when asked about it.

correct, my blow out was because of the pot hole causing the tire to hit the rim, gashing the sidewall, nothing to do with the pressure and a higher pressure may have helped it not blow out due to their being more resistance to the tire hitting the wheel.
if the tire's max pressure is 50, there's zero problem with running 50 and it's not going to cause a single problem. the mfg's tire pressures are recommendations, and in the end, the tire has to be referred to for max pressure amounts. less pressure has more of a chance of blowing out due to increased heat. the less pressure you have, the more rolling resistance resulting in more heat.... which will cause blowouts. Everyone remember the Firestone / Ford issue, that was due to low pressures. the only thing high pressure (max tire mfg. pressure) will cause is potentially a rougher ride, there is no more potential for blow out.

fully agree with every thing u said.

I ran our OEMs at 30-32 for the first 14K miles. Nice ride, but the wear has been high. Recently, I changed it to 36psi and the ride/noise predictably deteriorated, but I seem to have picked up almost 2mpg. I can't say for sure, because we only have a few hundred miles on the new pressure.
Also, as I mentioned, tire wear can be higher at low pressures. As the pressure decreases, the tire carcass flexes more. This alone will increase wear, but it also heats the tire more, with accelerates wear. Our mildly driven car's RE050s are looking pretty sad at 14Kish miles.

i have about 11k on mine and they are half haggard looking as well.
