Tpms?
Have a 2006 Base convertible and still had the original Goodyear runflats. So after recommendations from this forum I bought continental extreme contacts non-runflat. Wow is all I can say. The ride difference is night and day. Never runflats again. Also installed new z06 replica wheels so I changed out the tpms. A friend of mine with a shop mounted and balanced wheels and tires. I bought the tpms reset tool. Vxda el-50448. The tire pressure on the dash still reads the old pressure of 28-30lbs. The new tires are 51lbs. I tried the procedure like 15 times. Car in accessory mode,hold lock and unlock til I hear the beep than use the reset tool. But I never get the beep that tells me it read the new tpms and the pressure in the car still reads 28-30lbs. Any ideas?thanks

Just had the same tires and same Schrader's installed and Discount tire couldn't get the car into re-learn mode. Wound up taking it to a dealer who I think used a Tech-2 to get them to read. By the way, love the tires too!

Thanks. I was gonna take to the dealer for oil. I will have them do that also. I still need an alignment. When I took the front driver side tire off, the inside tread was completely worn right down to the belt. Honestly with these new tires I feel like I’m driving a different car. I can’t say it enough how much better the ride and handling is!!

Just a reminder that you can do the learn process before installation to make sure that all will work. You will get 0 pressure readings of course but you will know that your tpms will sync with the car.

First, can you explain the bit about the new tires being at 51 lbs?
Second, if you are driving around and nowhere near the old wheels and sensors and if the new sensors aren't programmed, you should be seeing 'xx' as the pressure. What you are describing doesn't make sense, no offence intended.

No offense taken. The new continentals take 51psi max pressure and that’s what I have in them. I’ve had the car out a couple times and I am getting no xx sign for the tires. I don’t know why but it shows the old tire pressure. Makes no sense to me. I’m getting conflicting information about psi. I see people running 38psi to 50psi cold. Kinda lost with this.

Look at your drivers door jam, it will say nothing about tires set to above 30 PSI, with that pressure it should be hard drive, and they will adjust it when you get wheel alignment other wise, it won't be set right.
Hope they installed correct part.
Lower your pressure just because the tires says it, you're not ride it at that pressure!

I have the same tires. Run them at 30 PSI. Yours are grossly overinflated.
Your tire pressure is set based on the car, not the tire. Inside the driver's door jamb is a placard that shows the proper pressure.

I recently got new Schrader 20076 sensors and the same reset tool you bought. Once in relearn mode you have to receive a beep at each sensor and a double beep on the last one or it is not working. Make sure that you point the reset tool just above the rim and at a angle and it should read. I read somewhere that the reset tool does not work if you have it placed on the rim itself. Guess I was lucky as it worked the first time for me. Also leave the door open once you have it in learn mode. I think shutting it will make the car go to sleep and that might be why nothing is working.

When the car is moving, tire pressure data is gathered about every 30 seconds. This is what I observe on my vette. If the car can't get a reading from one or more of the sensors it will throw up an error message on the DIC and a yellow light shaped like a tire will show up on the instrument cluster. If you scroll through the readings on the DIC, the sensors that can't be read will display xx for the pressure. I've seen this numerous times, as have others. That's the way the system operates. If the sensors in your car haven't been programmed, then by definition, they can't be read. The fact that your system continues to display the old values suggests a problem that needs to be investigated.
About the tire pressure, you are not the first to be tricked into thinking that the max pressure is what to use. As stated, it's 30 psi cold. If your TPMS system was working correctly, you would have received an overpressure warning on the DIC, which I believe is triggered at 40 psi give or take. I had this happen once when the shop overfilled 1 new tire.

This, with every car. Inflate the tires to what the car says, not the max for the tires.

Ok thanks everyone. I will bring the pressure down to specs in the door jamb. As far as the dash I am getting no xx or anything else. For shiots and giggles I lowered the pressure in one of the wheels I took off and the low tire pressure light came on in the car. The car and old wheels are in the same garage. Maybe I should drive the car out somewhere in the open and try? As far as tire pressure I always thought that the psi on the tire was the correct psi to fill the tire. All these years I had it wrong! Lol.

Ok so I drove the car away from the house. No difference. Car is still reading the old tires ,and still giving low tire pressure from the wheel that is no longer on the car. Tool was brand new and brand new Duracell battery for it. Also tpms brand new from rock auto with current dates on them. Lowered all tires down to 30lbs. Crazy

It might be the wrong TPMS sensors they sold you, might make difference with the correct ones.

If it makes you feel any better, the brand new tpms tool I got from Amazon didn't work either, with a brand new battery. Dealer reset them for me for free. Also, there's some evidence that a tune might interfere with programming the sensors. Does your car have a tune?
