Tire mounting question???
Did a search, didnt find anything helpfull, so here goes...
Im going Wednesday to get some rear tires changed. My question is there any special procedure when doing Corvette tires thats any different than any other tire change? I know theres sensors in the wheel, but is there anything special I should tell the guy before he does the change?
Thanks

Make sure you tell him that the valve stems are tire pressure sensors worth $150 each. If you have run flat tires you should ask them if they have had experience with these. The sidewalls are extremely stiff. Also mention 18 inch wheels. Good luck. Oh, I always tell the guys BEFORE that I will tip them ($20 for 4 tires) if no scratches or broken tire sensors.

Torque Issue
One issue I had was with the torque required for the pressure sensors. My service manual states a little over 100 in-lbs but the tire dealer had insructions that said the max was 40 in-lbs. I went with 40 and everything is holding but I don't know which is correct. Anyone know for sure?

Tire sensors do NOT have to be removed, Correct torque for 1998 sensors is 106 INCH - pounds. Remember sensors are only good for about 8 years and 100,000 miles (whichever comes first). If your sensors are close, buy new ones fron Frichtner or Fred Beans ($80 a piece).

Orings
I don't know if you must but I would. It appears that the sensor might be in harms way if you don't drop it down into the tire before breaking the first bead. I'd remove them to keep them from being broke and I'd replace the orings while I was there. I'd also look for someone that has Hunter tire and force balance equipment. It was suggested in one of the vette mags and I was please with the way the equipment was designed to protect the rim and the balancing was hi tech.

Same here. Maybe not mandatory, but safer for sure.

Look on the tirerack.com website. They have a list of installers and may have some in your area. This would be a start. The recommended installaer in my area (Edmond) is so busy you have to make an appointment, and they did excellent work. The tires were road force balanced.

Schrader/Bridgeport now makes replacement pressure sensors. I haven't needed to replace my sensors (yet), so I don't know how the prices compare to the OE units. It would probably depend on whether or not you're "connected" at an auto parts store.

Your car is a 99. More than likely they were built in 98, Your sensors are 8 years old, if you are lucky they will last the year, Many people have had TPS go on their 00. I would put new sensors in, I would buy them from Fred Beans. Gene Culley at Fred Beans has the best prices and service.
If you do not replace them NOW, you will shortly have a DIC warning everytime you start yor car, you can not disable it. YOu will have to put new sensors in... If you dont do it now, you sill have to pay a premium ( extra cost and your time to take the car in a second time ).

If you do not change the sensors NOW...I suggest you have the service writer verify the condidtion of your wheels, and also verify that your sensors were working before they touch your car...
