TPMS or not for track setup?

Bought a set of RS3 265/285 earlier this year and just now found a set of Apex 10" wheels.

The question is, should I install TPMS on these?

Please help...

Apart from cost, why not? Nice peace of mind to get alerted if a tire is going down. Without them the warnings would annoy the hell out of me, too.

I'm a little afraid they won't get the balancing perfectly, and with the high track speeds it would be very obvious...

I've got them on my stock and lightweight wheels and haven't had any issues at track speeds (up to 130 or so for me.) Three different sets of wheels and various tires in stock and plus sizes.

I went with "no" because, at the track, your starting pressures will be low enough that it will just set them off and you will get annoying warnings... so hardly useful. So it really is only potentially useful if you are spending a lot of time driving on your track tires away from the track.

The warning is actually LESS annoying without it -- as it merely dings twice upon startup and then leaves the light on. With TPMS installed, you get obnoxious iDrive intrusions and reminders constantly while driving.

When you put on your track wheels and you have low enough cold pressures to set it off, just reset the TPMS and you are good to go till you put your street setup back on. Takes about 10 seconds and no annoying warnings.

I forget the exact threshold but I run stock at about 34-36, cold pressure for track starting at ~30. No warning for me (I think it will trigger around 28-29 in my case, roughly 7 psi or ~20%.)

Why do you want to run a staggered setup on a square set of wheels?

In regards to TPMS they are 100% unecessary.
You won't hit a nail or anything on the track.
It's just a pointless thing to do IMHO.

If you absolutely want to run them, that is fine too. They won't cause any balancing issues.

As I daily & track the same set of wheels & tires, I have the OE TPMS on my R-S3/Apex.

At the track, I just initiate 'reset' before beginning sessions and, in no time, the warning goes away.

Never had any issues w/ balancing.

I was running my OEM 19" on the track until recently and went with TPMS to avoid the warning light. I didn't see any issue with balancing or anything like that but was finding that having to reset TPMS was an unnecessary annoyance.

I just switched to RS3 square on Volks G2 and went with no TPMS this time. Sure, the warning light is annoying but I find it less annoying than having to reset TPMS at the track.

My take is no TPMS if you use the wheels for track only and TPMS if you use the same wheels on track and street.

Thanks guys.

I went with square wheels because in the future I will probably run square, but found a great deal on the set of staggered tires first.

Crap gets dropped on the track too. All the time. Had a good friend slice open a brand new NT-01 last spring - someone in the prior session left a gift just off line and he picked it up passing someone else on his second lap out.

This wasn't my experience I kept having to repeatedly reset it throughout the day, not just once in the morning. Though my cold starting pressure is less than 30. I really felt that they kept kicking on at a far higher PSI level (more like dropping below 33-34...) Sounds like my experience might be more of an outlier, however.

+1 for this reason on the track.

I didn't install TPMS on the new wheels, simply coded the TPMS system out, reverting to RDC mode (wheel sensors).

It shouldn't give you a warning for high pressure, just if you drop a certain amount *below* where it was when you set it. Don't understand why it would keep coming on.

Tom, when you say RDC, is that the E46-stye method that measures changes in speed of rotation?

Only set I have TPMS on are the stock set. I routinely check my tire pressure & believe I can feel/see anything abnormal.

I run TPMS on my track setup Arc-8 18x10 square. I just reset the TPMS once when the wheels are changed out. I have no issues with repspect to lights coming on during sessions on hot or cold days.

I like the TPMS peace of mind personally. If the warning light gives me a few extra seconds to slow down and prepare before the tire fails then that works well for me.

There must be a valid reason why you would want to do this, but for the life of me, I cannot understand why. If your car is not handeling and your car control is that far off, then I would suggest you are doing something wrong besides tire pressure. Are you considering run flat tires?

I wouldn't run it on track wheels, not worth the money.

The balancing thing is a complete non-issue. Plenty of guys race on wheels/tires that haven't been balanced at all, all it does is cause vibration, which we all had plenty of with aluminum motor and trans mounts and zero sound deadening anyway. Don't worry about it!
Related to that, I once had a tire shop put some used slicks on a set of wheels for me and they had so many track boogers on them the shop had to use like 20-30 balancing weights, and when the boogers wore off in the first lap or two the wheel shook way worse than unbalanced ha.

I know I'm reviving an old thread but i'm just looking at tpms and how it would help at the track.

My understanding is that the system with stem sensors sends a signal at a given interval to the computer. This can be up to a minute apart which seems to me like too long to be of any use on the track.

Would our EU system that uses the ABS sensor react any faster?

One of my mates had a tyre lose pressure down the straight. It wasn't a total blowout so he didn't feel it immediately. Coming into the first corner the car lost control and rolled several times. Just wondering if any of these systems would help in this type of situation?
