I just bought a 2006 TL from a luxury used car seller. I'm a dumb girl, I thought it was great to get a carfax and thought the car was in great shape. Had it for 5 days and the TPMS tripped saying 'error'. Hubby checked the pressures and all tires were roughly 38psi. Specs say psi should be 33psi/32psi. Why would dealer pump higher that what is clearly listed on the specification label on the door frame?

Oh, and the TPMS sensor was busted. My mechanic thinks whomever the dealer used to put the new tires on the car caused it to break. Unfortunately, I have no service contract or original warranty left. You wonder why folks have little respect for car salesmen?!!?

Im not expert but the tire pressure has to be checked in the morning or before its been driven over a mile to get a correct reading. If you drive for a while the pressure inside the tire will get hot and thus giving a higher pressure.

I set my tires for 38psi all around because im running performance tires and I feel with 38psi the car drives just as good or better than having what the manufacture recommends.

Also the reason the manufacture recommends 33/32 psi is for best fuel economy rating not for driving pleasure.

Also, there could be different tires on the car, other than stock, which call for a higher/lower pressure.

in that case, you would disregard the placard.

not all car salesmen are bad.

it'll be hard to put any blame on the dealership at this point. it'll be a bunch of he said/she said games.

i'd like to say that you didn't get "had"...but it is possible that the guy took advantage of you being an unknowing girl who's buying a car. no offense meant.

always always always have a mechanic or trusted car pro check out the vehicle before you sign anything. were talking about a lot of money here, i wouldn't just sign something and hope for the best. i have to KNOW that my vehicle is up to the proper standards.

hope this gets resolved for you, sorry you had a bad experience.

Many believe to know more than the OE manufacturers and create their own pressures. If you look on the Forum you'll find people running over 40lbs, beyond me!

Yes, a novice shop worker will break the sensor(s) if they don't follow a specific procedure for tire removal and installation.

I would imagine the dealer probably kept upping the tire pressure to try to get the TPMS light to shut off, not realizing that it the culprit was actually a broken sensor. Try to get the dealer to replace it for you. If not, just have it replaced at a local reputable tire shop. Aftermarket companies like Dill and Schrader make OE replacement sensors that cost about half what the Acura dealers charge for one.

i got new tires installed 245/35/19 all around nankang II and the seller had the psi at 45 all around. i did not notice it until i checked my self cause i was feeling the car to rough. i set them to 38 front and 40 rear not the different is like night and day.

The stealerships up the pressure b/c they are a bunch of idiots. One time, when I was having my FX serviced I specifically told the service advisor and the technician who came out to work on the car not to air pressure to the tires and leave them alone.

Well low and behold, the ride home was extremely jarring. Next morning I measured the pressure cold and it was 42 PSI. Up from the 35 PSI I normally kept it at cold. Unfreakinbelievable.

What's your impression on the Nankang tires so far??

Wrong. Radial tires of same size/load rating as OEM, use OEM recommended pressure.

I've also heard that it helps the bead seat to the rim

I run 3 -5 lbs over the recomended pressure.

Because I can.

Nope. Tires can be the same size and load rating but with copletely different carcass construction requiring different pressures.

Max inflation pressure is not a good one either. My new tires have a 50psi max yet they start to get worse traction past 38psi.

I never knew tires could be so complicated. So answer me this if you would, why is there a spec label on the car if the tires, which are replaced every few years (-ish), have different specification for psi?

The spec label is for the OE tires, so if you replace with the OE model, the label will be correct. Actually if you replace with vitually any A/S tire of the same size, the OE factory pressures can be used. If going to a larger size and/or XL load rated tire, might want to lower the OE pressure maybe 1 lb.

Okay I understand now. Thanks Turbonut.

To take it a step farther, the OEM recommendation is supposed to give a decent compromise of wear, comfort, and performance. It's more of a rough guideline. Adjusting up or down a little is not a big deal.
