Help! Tire pressure warning
Hey everyone,
I replaced my rear tires on my 2001 vette from Runflat goodyear (stock) with Kumho ECSTA MX XRP RunFlat. Doing this I keep getting the pressure warning. The Goodyear tires where set to 32 psi (avearge), the Kumho are set now to 42psi cold and go upto 46 47psi hot, which is normal for the Kumho. Now my question should I reduce them to the Goodyear pressure or is there a way i can reset my rear tire sensors so they understand that 46 47psi hot is normal. Any recommendations are welcome.
Thanks

You are way too high. Tire pressure has a lot to do with vehicle weight. You will wear out the center of your tires in no time with that much air pressure. Try 30 psi to start.
The maximum air pressure on the side of the tire is just that, a maximum, unless you have that weight car (like 4 X 2022 pounds or 8,088 pounds) you should not be using that tire pressure.

ramez75,
I'm guessing you got this 42 psi # from the tire sidewall ?
You, and unfortunately too many other people, are apparently misinterpreting the MAXIMUM tire pressure inflation information, imprinted on the sidewall, as being the pressure at which you should be operating your car. Start with the same pressure as the OEMs - 30 psi, and then MAYBE you will find you want to vary that by a pound or two either way.

The shop who istalled them interpreted it like that, it didnt make sense to me, so I said let me put a post. I was about to reduce them to 32psi just like what my Goodyear tires were at.
When i debated with him, he said if i reduce the pressure i will effect the life of the tires which like i said i didnt but it. I really appreciate all the input from you guys.

This is frustrating each time i replace something i end up doing more work and spending more $$$.
I am considering buying my own tools and transforming my garage to a workshop so i start do things myself. (I had to let it out )
Anyways i work in MAcon and live in Savannah, Georgia (on the weekends). Does any one know a reputable corvette shop that i can go to and dun worry about the vette that is in the vicinity.

These guys shouldn't be in the tire business

30psi when cold.
You are get message because the tire pressure is 42 psi or greater.
Check it out in your manual if yo have one.
Here is what it says
HIGH TIRE PRESSURE - (LF, LR, RF, RR)
(Except Z06): You will hear two chimes when this
message is displayed. To acknowledge the warning,
press RESET. After you press RESET, a message will
reappear every 10 minutes until this condition changes.
This message indicates that the pressure in one of your
tires is higher than 42 psi (290 kPa). Next to the
HIGH TIRE PRESSURE message, you can see either
LF (left front), LR (left rear), RF (right front) or
RR (right rear) to indicate to you which tire is higher
than 42 psi (290 kPa). You can receive more than one
tire pressure message at a time. To read other messages
that may have been sent at the same time, press RESET.
If a tire pressure message appears on the DIC, stop as
soon as you can. Have the tire pressures checked and set
to those shown on your Tire Loading Information Label.

The car specs determine the proper inflation pressure, not the tire unless there is a drastically different design reason but I've seen a tire with any.
