TPMS alarm: How bad is it?

I'm looking at getting a set of winter tires for my wife's 2011 335i from tire rack. It's $228 for the four TPMS monitors but I'm wondering if I need them. My question is:

How annoying is the TPMS alarm? Is it just a few chimes when the car is started and a light on the dash? Can the computer be reset to not look for the TPMS sensors?

If I do get them installed, will they work, or am I going to be making a $ trip to the dealer to get them programmed?

I read on this site that in mid 2011 there was a change in sensors. Ours is a June 2011 built car. Should I tell tirerack that it's a 2010 car just to be sure I get the right sensor?

My main driving function is to minimize hassle. I don't want to go to the dealer b/c its a pita, and I don't want to futz around with tirerack if they f' up and install the wrong sensor. I don't mind the $228 for the sensors but they goddam better work with very little effort on my part. I'd rather just put up with a couple chimes at startup and a light on the dash and keep an eye on the tires myself than deal with a wrong sensor install or take it to the dealer.

Anyone have experience not running the sensors?

You'll only have an annoying and constant visual dash warning if you don't put them in. No, you can't shut it off unless you start getting 'creative' with the wiring.

Just give the Tire Rack your car's build date...they'll make sure you have the correct TPMS. They should 'auto' program and start working according to your car's reset procedures but I'm sure TR can help you with that also.

Umm you can code the system off

Find a local coder

The system can be coded back on later.

I would just get the sensors though

There's no issue with changing over sensors between tire sets if they have the right modules in them. Tire Rack sent me the right ones for my car. When I put the winter set on, I just go through the reset procedure with the turn signal stalk. No big deal at all, no trip to dealer required.

If you're thinking about going without, you may wish to think again. If you get run-flat winter tires, you should NEVER run without TPMS. You may have lost all pressure in a tire, won't see it, and won't know it until the tire fails dramatically. If you run with go-flats, you may find it difficult to get them put on and off your car or have them repaired. NHTSA is cracking down on tire shops that mount non-TPMS setups on cars with TPMS.

Well _that's_ a great use of taxpayer money, harassment of small business owners. Beautiful. Not like 9 of 10 new jobs is created by small business or anything. Could the government possibly be any dumber?

As long as programming the car to recognize the sensor is as easy as selecting 'reset' in the dashboard menu, I'll give it a try.

I wish I could get the psi to read out on the dashboard, but it doesn't seem to be an option.

Thanks for all the help!

You could also manually check tire pressure. Like they used to do before TPMS.

I have FTM in my 330xi but even with newer cars I drive that have TPMS, I also manually check. I never got used to trusting the sensors and probably never will

I swear by the sensors. More than once I have had a tire go down at 100mph plus speeds where the sensor went off. It was correct.

I'll go ahead and install them. Even if it's just a couple chimes and an annoying light on the dash it's worth it to avoid those as long as it's not a hassle to make the new ones work.

The sensors are $228 extra to install on the four wheels, it's optional. Even though I indicated the car it was going on. So maybe b/c TR is not physically putting them on the car they're not required to install the sensors? I'm just buying wheels and tires from them, plus the sensors now.

Check the "coding' section of the forum ... I know on F10 series both the (actual) tire pressure and temperature reading can be coded to appear in iDrive.

Yes, you certainly can.

But unlike before TPMS, if you have runflat tires, they look fine when you walk out of the office and get into your car. Excluding a few OCD loons, people didn't check their tires each and every time before they drove, but many looked at them to see if they were flat. Now, you can have zero pressure and pull out of the space without thinking.

Roll up onto the highway, set the cruise at 75, head off to the summer place in NH (150 miles away), and wait for the fun as your sidewall comes apart 2 hours into the drive.

But, hey, let's go OCD. Check your tire pressure before every time you drive. You still won't know if you ran over a shard of broken bottle backing out of the parking space, dropping your pressure to zero and setting up the same case above.

The bottom line on this is that if you have runflats, you must have TPMS, unless you plan to check the pressure each and every time, never drive more than 50 miles at a shot, and never drive over 55.

Yup, so do I, because the TPMS doesn't trigger until you're low enough to negatively effect mpg and handling.

I got TPMS sensors from TR for my 2009 E91. I had my winter tires mounted at a local shop and put them on and they worked without any resetting of the system. I actually let some air out of one tire just to make sure they were working. If it's your wife's car, I'm betting that any alarm going off will annoy her (it would annoy my wife).

"Coder"? In the federal rulemaking for FMVSS 138 (mandatory TPMS), NHTSA specifically stated that there would be no provision, allowance for shutting off the malfunction indicator light. Doing so is illegal under the statute.

I've never heard any chimes when my TPMS warning went off (indicator light) and in the rulemaking process for this law, no audible warning was every discussed or required.

Well, I am sure people said the same thing when ABS first came out It was (and is) illegal to disable that system as well. Same reasoning here. If you didn't have any regulation you would have people driving around on bald tires and no brake pads.

Think about the money the "small business" gets to make over checking and maintaining these TPMS systems. I wish people would stop and think about both side of the coin before immediately jumping to their gut (misguided) reaction.

Riiight. Burdensome, overbearing govt bureaucracy is actually good for small businesses. Riiiight. (<--- this is sarcasm btw)

We'll have to agree to disagree on that idea I guess.

Ah, the "Broken Window" fallacy.

The concept breaks down in the usual place. The money spent checking and maintaining these systems doesn't leap into being as Athena sprang from the head of Zeus. Rather, it is diverted from other opportunities on which the vehicle owners would prefer it to be spent.

Ah yes, and this is the point to some degree. People shouldn't be able to choose spending money on some shiny new wheels over a safety device (TPMS, new brakes etc.). Balance between the two extremes is key.. often forgotten.

Lets fix your flat tire, oh you need a new sensor along with your new tire. Sure, that doesn't generate anymore money. I would rather just buy the new tire.

Yup, so do I, because the TPMS doesn't trigger until you're low enough to negatively effect mpg and handling.
A flat RFT will handle MUCH differently than a properly inflated one.

I see your point about having a tire low and not noticing. But even then, when I had RFTs, I would notice the front side with lower pressure pull when braking and the rear side when accelerating.

People just don't pay attention to how a car drives. As long as the engine starts and it moves, that all they care about.
