TPMS and new wheels
I know this has been addressed elsewhere, but I just wanted to pass along some info about the TPMS system. With winter coming in nice and strong (2 feet in Washington DC), new tires will probably be needed. I was talking to a buddy of mine that works at NTB and asked him about the whole TPMS as well as one of my techs. They tell me that you can swap the tires out with no problems. Yes, there are exceptions, so make sure if you get new tires, it fits with the TPMS system.
Now with switiching out wheels. The TPMS Sensors are removable and can be swapped into other brand of wheels, BUT no all. Make sure that before you buy the wheels that that TPMS fits. There is no way to disable the system, so just leaving them off would be a very annoying thing. It wouldnt be bad if it were just a light, but they have to add a buzzer lol.
Has anyone here changed out tires and/or wheels yet? Any problems come from it or anything like that? If you changed out wheels, what kind of wheels were they? I havent dealt with this situation yet, but I would like to be perpared when I do.

As for TPMS - not an issue for us Canadians, since our RX-8s don't have the TPMS system anyway! However, there are plenty of Americans who've already checked this (and posted about it). Without the wheel transmitters, it's supposedly not that annoying at all - after several minutes, the TPMS light comes on steady, and that's all - no flashing, no buzzer. Not much different than the headlight indicator or the DSC OFF indicator.

SnyderMazz,
Please see if you can find out what is in Tech Assistance Reference 322819. With it, the Mazda Tech Line told my dealer that the lack of the wheel sensors would not only affect the TPMS but also ABS and TCS/DSC. They said there would be a buzzer or chime after a certain number of cycles.
I have winter tires on 17" wheels without TPS. All I've seen is the flashing yellow light after about a 10 minute delay after every start-up. I've also had ABS and TCS work fine.
My Service Manager said he'd contact the Tech Line but I haven't heard anything back in two days. I think that Tech Assist. Ref. ought to be corrected or retracted.

I just put my winter wheels on last night, and after driving to and from work I haven't gotten a TPMS beep or light yet. I had a light on already from my stock wheels when I did the swap, but it went away and hasn't returned yet. Any ideas? My trip to work is about 10 minutes one way.
I think it would be really cool if this were the way to defeat the system.
Crap. nevermind. just saw the bit about 3 minutes above 16 mph... that never happens on my drive.

Hi. I'd hate to see someone make a decision based on incorrect information.
According some of the posts I've seen (and quoted below) and page 5-26 of the RX-8 Owner's Manual - the TPMS light will be flashing (not be steady on) if TPMS sensors are not installed.
Your post is potentially misleading to people who may decide to buy wheels without sensors after reading it and thinking the TPMS light won't flash - then find out about the flashing light later.
It may be helpful if you post your source for this contradictory information - that the TPMS light comes on steady with no sensors installed.

It's really not all that annoying, but some people have said a little piece of black tape covers it pretty cleanly. I only heard the beep the first time the light came on with the stock 18" wheels/tires after a temp drop caused some low tire pressure. No beeping since.

I'd agree with buying the sensors in this case. I have a 2002 Audi with a similar TPMS, except it can be simply turned off from the computer menu. I looked into buying transmitters for my winter wheels, and at the time they were quoted at about $270 each! (more than the wheels I wanted to mount them on!!). I decided to forego the transmitters at that time, so for the winter I have the TPMS disabled on the Audi. When I have to replace the winter tires, I'll get transmitters to install then (they're much cheaper now).

Gordon

The TPMS warning light with the winter wheels is not very annoying to me. It's a fairly slow flash cycle, approx. 1/second. Plus there's about a ten minute delay after each start-up.
Mazda missed an opportunity to sell winter tire packages with sensors. I asked the RX-8 support line about this before the 10/1/2003 buy-back decision deadline. Their answer was that, no, Mazda would not be offering winter tire packages because they do not make tires. That answer seemed to miss the point. I wasn't suggesting that Maxda begin tire manufacturing. They can certainly market what they don't make. It would have been better customer service to offer a discounted package while avoiding uncertainty about the TPMS and wheel fitment.

Remember what the sensors do?
There have been many posts about the nuisance of flashing lights if you don't have sensors. How about the loss of warning about too low (or too high, BTW) pressure in one or more tires?
The 8 comes without a spare, and most people leave it that way instead of losing half a trunk and about $400. Isn't it worth something to have a warning that might save a dangerous situation,ruined tire and being stranded? Granted, that will happen rarely, but I for one want all the help I can get.
Mazda is obviously less impressed, because they don't offer the system in Canada, where it is not required by the government.

Good point - I've seen a number of posts where people have stated that with the colder weather, their light came on because their air pressure was too low (because they had not adjusted their pressure since the temps have dropped).
I've gotta wonder how many people have been similarly warned by the TPMS, but don't post?

With the TPMS system we've got in the 8, visual inspection of tires and occasional tire pressure checks will serve as well. That is, when running winter wheels, or other aftermarket wheels, do what you did before you had TPMS.

Zoomalot, I almost agree
I don't like to quibble, especially with someone from my wife's home town, but you left out one word: almost. You say that that the pre-sensor routine of visual tire checks and occasional pressure checks is as good as having sensors. But the previous routine was with previous conditions, namely five tires. I didn't worry about the rare situation where outine checks wouldn't catch a tire before loss of air caused big damage. No big deal; toss on the spare. Now it means trying to repair a tire on the road (having to replace it if you use Mazda's goop) and maybe getting stranded if it can't be repaired. With those possible consequences, the old way is no longer quite so worry-free. In short, the sensor advantage is more important for the 8 than for other cars.

Mitch,
Thanks for almost agreeing, and not quibbling too much. It would be fair to add the "almost" qualifier to my statement. It was enough of an "almost" for me not to see the value in an additional set of sensors.
Another element of the previous condition in years past was less reliable tires. Except for hitting a nail or debris, there aren't many tire failures these days (properly inflated tires, that is).
In the case of sudden unexpected deflation, I don't think the TPMS will help. It's meant, I believe, to warn of relatively minor differentials in tire pressure so that you can adjust to proper levels. A tire that needs repair will cause a ride on a rollback to the nearest dealer for me, most likely.
Our cars aren't equipped with the TPMS because we lack a spare as standard equipment. Our Canadian RX-8 brethren don't have TPMS, but their cars didn't come with a spare tire as standard equipment either. (Or did they? Am I wrong?).
We have the TPMS because of a Federal regulation that I would guess arose from SUV rollovers due to overheated, underinflated tires. The SUV driver can barely sense what's going on down at the tires. In our vehicles, we'll be able to sense a tire getting low.
Now, if we had a TPMS that displayed the pressure readout of each tire, then IMO we'd have something worth preserving with an additional set of sensors.

As I recall, it signals at 6 psi under (26) and a larger margin for excess inflation. When I measured my winter tires cold after dealer installation, they were all about 4 psi under -- which was fun to fix with the in-car compressor.

I will probably be cautious, too, but there are situations where I would like the option of field repairs. The earlier the loss of pressure is detected, the greater the cnance that the tire can be repaired successfully, and perhaps even kept in service.

I'm not sure I would catch it as reliably as TPMS. The car rides so stably, and it just might be cruising straight ahead on smooth Interstates after catching a nail .

I have read that future systems will have that feature. With separate sensors in each wheel, I don't see why Mazda couldn't have done it for us this year. It would seem to require only that each sensor's signal be identifiable by the pickup, plus adding appropriate displays to show wheel location.

I guess not everyone can sense when their tires are getting low as you say you can.
People have posted that they did not adjust their tire pressure when the temps dropped. As a result, on cold mornings, their TPMS light was on. After they realized what was going on and inflated their tires to the correct psi, the light stopped coming on. I'm afraid this is one of the reasons the Feds have mandated this system on us.
Yes this system won't help with a blowout, but it will give you an indication of a slow leak or need for a seasonal pressure adjustment
