Most of the oil changes that are not regulars have under-inflated tires 99% of the time anyway.

In your position I would do the same, unless requested by the customer, and I wouldn't go beyond the max PSI rating on the tire.

Curious question though, what is max inflation tire rating many of you have on your tires? For me it is 44 psi max, and I try to stay around 41.

I did a Cheesy-Lube a while back. It said 32 PSI on the receipt, but when I checked, they had left it at my original PSI.

I specifically picked my tires for their high 51 PSI rating, and that's what I keep 'em at :

...never exceed the MAXIMUM pressure value printed on the sidewall of the tire.

Unless you're feeling adventurous, like some of us here.

As stated above, the maximum pressure is listed on the sidewall. What's safe? I'm not going to open that can of worms. Do some searching.

I read an article once that went very much in depth on how high you can inflate a modern tire. the burst pressure is like 2-3 times the maximum sidewall, so keeping it at sidewall pressure is likely the best bet.

I was getting a key made one time and the mechanic came out to let a waiting customer know that he broke off the pressure sensor inside of one of his tires. Stated that the part would be $85 + labor and he was not allowed to take the car somewhere else for the repair, because the law stated that the tire could not be remounted without the sensor.
He brought it in to have the a slow tire leaked fixed and it ended up costing him @ $150.00

My 1st Camry, ever single wheel stud snapped over a period of 2-3 months
as all of them had been air gunned to hell by dealer who swapped on "inspectable" junk rubber before I got the car.

Another great one was the Ford Dealer who over filled my Mazda3, 6qts in a 2 liter?

OR the Jiffy Lube Pro who filled my car with 5/30w even after I paid the extra $10 for semi-sythetic 5/20w that was spec for the Mazda.
When I noticed them doing that I gently reminded them and they drained it an d fixed it. 500 miles later my oil filter feel off and Mazda towed my car in (free roadside assistance) and checked my engine, said looks like you got lucky BUT your warranty is null and void.

They let some air out of my wifes monster Michelins on her Pilot last oil change at a Valvoline EVEN after I asked them politley not to.

We signed her car up for the Valvoline Oil motor warranty. As long as we use the semi-synthetic they warranty the motor until 125K, its at 65K now.

My Camry oil filter sits at a 45 degree upright position right over cross member. Messy change unless I do the drain all oil, put oil plug back on, start car, shut off after 5 seconds, drain rest of oil. That seems to get the cup or so oil out of the oil filter. Spin it off quick and turn it upside down and no mess.
