I recently mounted a different wheel and tire set for an upcoming DE. They do not have TPMS. My parts guy, who tracks frequently, says its ok. Anyone think its a problem passing the tech inspection? tks

 

No problem.

 

Tech? I'd say 95% of all Porsches do not have TPMS. You will have a warning light on your instruments is about all. I always put TPMS sensors on my track wheels to be able to monitor pressure during events. Not because I think it's accurate, but because it will show me rises and drops in pressure. Had 1 situation at Watkins Glen where I had a valve stem failure that slowly made me lose pressure. Knowing that pressure is dropping is useful.

 

TPMS on track wheels are a pain anyway... I have them on my track wheels and I get a "flat tire warning" at the beginning of every session because of the lower starting pressures... I might as well have saved the $400 and just lived with a "TPMS not working" warning instead...

I don't think it would matter for tech as it really doesn't affect the overall safety of the car.

I've had problems with odd readings on track as well. I got a flat warning 'after' the tires had come up to pressure. For my next set of track wheels I'll leave the sensors off.

 

Either way you are going to get warning lights. On a $100,000 car I didn't think spending $400 for track TPMS sensors was unreasonable, especially when it can provide a useful function.

I always have the 4-tire pressure display on my car. So on the track it just reads out the pressure and I don't even notice the 1-time warning. Mine will go from say 23 psi to 35 hot on the track and that's where it's useful. If I see the 35 start to drop on the track, I know I have a failure somewhere and can pit in.

 

No problem at all.

What DE are you getting ready for? I see you are in Dallas...is it the PCA DE at MSR? If so, I'll be there as well. Have fun!

 

Yes! If they gimme any $hit, i'll let you loose on'em!!
