Hi,

Took my 2003 ES300 into the local Discount Tire to rotate the year old Yokohamas. I was checking the tire inflation a few days later and found them all at about 40psi. The door sticker recommends 26psi and I normally run them about about 30, but why would the shop inflate them to 40?

Can this level of pressure harm them?

stock rims? or aftermarket with low pro tires?

Stock rims and equivalent tires.

Very simply, they screwed up.

Good for you for double checking.

I always check my tire pressures the morning after any kind of service and most often find them at around 40 psi. I'm not sure why other than better gas mileage or do they assume the tires are really hot or something which is unlikely unless you were in quite a hurry getting into the shop and then they got to the car very quick. I usually know as soon as I drive away from the shop because of the hard ride.

I think the recommended psi on 02 ES is 28 or 29. I always keep them around 35

I rarely take my car to the shop, but I've also noticed they almost always over inflate, regardless of the shop. I just chalk it up to laziness, they just shoot some air in the tires to check it off their list without actually seeing what's being put in there.

I remember a month or so later checking the air in my tires after taking it in, and was astonished when my gauge said something like 43 psi. I couldn't believe how much smoother the car rode when I backed it down to normal.

I recently put some air in my 02 ES. The oil change place usually puts them at 40psi ( max is 44 psi on the tire). They weren't the same that's why I got air, they all varied but in the mid 20's. Now the ride certainly turns easier and grips better but it is WAY too firm on the bumps and sewers, etc. Definitely can change the way someone can feel about the comfort/handling of a ride. I now know to take it into consideration during a test drive.

This is really strange that so many of you have had similar experiences. You would think that with how lawsuit happy our society has become a shop wouldn't inflate the tires to anything except factory spec. I'll move them back down to ~32 and remember to keep my eye on this in the future.

I think it was something they overlooked.
The only reason most shops would ever over inflate a tire is to set the bead on a new tire. Once it's set, they should bring the pressure back down to spec.

It's good that you guys are checking cold pressure instead of later in the day.
A 32 psi tire cold could see anywhere from 38 - 44 once it's warmed up through highway driving or aggressive cornering loads.

I would still personally check tire pressures, it something easy to do and you should do it often. I check mine once a week or two.

this is intersting, i like to keep mine at about 32, the lower the psi the better the traction

Unless you have runflats, ES's ride a little soft. More air lets tire run COOLER, therefore lasting a little longer. Helps handling too. Unless you have a date with preparation H on a daily basis, most enthusiasts recommend it.

My 98 is always at 37 to 40psi...the doors sticker is based on certain tire size..bettering control and mpg's.

really?
This deserved its own thread?

If its 'so problematic' for you, release some of the air, or next time top it up yourself at a gas station?

I have mine on ~36-38 PSI
