So this weekend is THE weekend that I'm going to mount and TPMS marry my new wheel/tire set.

Problem is, it's been sitting in my basement for the last 3 months or more. It has the orotek TPMS sensors, and from what I've heard and read, they go to "sleep" and need to be woken up prior to marrying to the car. In order to wake the sensors up, the tires have to be completely deflated, wait 15 minutes, then inflate again, then marry. The sensors will then emit the necessary RF signal needed.

So obviously, I've never had the need to deflate a vehicles tires lol... My question is, is there a chance/risk that I can break the bead or seal between the tire and rim that when I inflate them again with my air compressor, it will leak? My nightmare would be if I have to take it to a shop to reseal and then risk them scratching my wheels. I don't want to have to kill anyone this weekend, if I can help it.

Fwiw, I plan on just laying the Milans on their side, and doing the deflate and inflate BEFORE mounting them on the car.

Any advice?

 

They shouldn't they won't have any weight on them. Just deflate, without pressing on the bead after the air is out, then inflate.
Also if the bead did break there would be no reason to put it on the tire machine. You would just need a bigger air compressor if it wouldn't seal back up with yours.

 

Probably won't break if you don't have weight on it. But if it does, it'll only be one side. So do this:


And then this:


Just a tire. It's NBD unless your compressor is a WIMP. Also, use soap, that first video, he didn't, nasty rusty rim, he deserved to be hit by that flyin' weight. Not hurt, just... surprising him and a small bruise, that'll learn him.

/As always, use your OWN discretion, don't be stupid, don't get hurt, and don't blame me, I didn't *FORCE* you to do anything.

 

Thanks for info.

I only have a 125psi 4 gallon craftsman from sears. Will that be sufficient? I think tires only have to be pumped to 34psi approximately, right?

 

I checked my tires leaving the dealership and they were pumped at 37psi (michelin green x 215/45?/17) and i think the sticker in the door jamb says 35psi recommended

 

With tires that low profile and the fact that there won't be any weight on them I would have to say the bead is fine. It takes quite a bit of force to break that seal once it pops on there when you first inflate them on a wheel. I'm sure you will use something to put underneath the wheel so that it won't get scratched in the process.......pillow top mattress maybe. You should be just fine. Please let us know how it goes.

 

Pillowtop mattress? I was thinking more along the lines of a memory foam mattress

 

Thanks for the info Steve. Yeah I never had to do this before, so this is bizarre for me.

Another crazy part about all this is, I'm going to have to do this process EVERY YEAR, every spring. Why? Because I will be mounting my oem setup every winter during storage months . So every time I store my Milans, the TPMS will sleep... Arrrrrgh... IMO, it's a stupid design from a sensor standpoint. Had I known about this beforehand, I would have requested a different brand TPMS.; Perhaps one that either never shuts off transmitting, or automatically turns on when the wheels rotate (i.e. Driving around the block)... Or even turns on via another method. Just annoying that I have to do this every year. I can't be the only one in the car world of enthusiasts, that has 2 sets of wheels/tires.

And yes, it will be a pillow top, cushy, and I'll probably have a butler around for each wheel

 

too much air in them.

 

The sensors won't come back on with just driving them for a while?

 

From all I read and researched, esp when talking to my vendor (they've sold a ton of these setups with the orotek sensors installed), they go to sleep if not receiving a signal back from the car (after a certain amount of time). The only way to wake them up is to deflate inflate.

 

Just turn the TPMS off with your tuner. You're a man aren't you? You're OCD aren't you? I'm sure you carry a tire gauge in your car. Just visually check them before you drive, and then check them with the gauge once every two weeks and you'll be fine. We've ran without TPMS for 100+ years before they were federally mandated in 2007 because of America's retarded drivers. I don't need them and would never stress about this if I ever buy a new car. I'll just have them disabled.

Some people have just made four little PVC tubes, sealed them with the factory TPMS sensors inside, inflated to whatever the factory psi is, then left them in the trunk. If I couldn't disable them with a tuner, this is what I would do. No more headaches!

 

TPMS cannot be defeated with a programmer…I'm not even sure a dealer has the ability to do it and doubt they would even if they could for liability reasons.

Burton,
You situation sounds odd to me. OEM sensors will not lose com with the computer, at least I’ve never heard of it and none of mine have ever done that.…don’t know why your after-market ones would either. I have heard that in order to “Retrain” the computer to the sensors in the event of a tire rotation or tire change (Which is essentially what you’re doing) a pressure drop below the low threshold (Typically 25psi) is sometimes required but not a complete deflation of the tire. I neither case, your beads are not going to break by simply deflating the tire…trust me on this one, I’ve mounted/dismounted enough racing tires to know that!

I see. I wasn't sure since I've never had to deal with this problem, but I have seen people do the inflated pipe thing.

 

Lol Patrick... You're missing the point . But yes I am a man's man!!! Haha

 

not to make you feel bad, but if you had OEM Ford sensors, you wouldn't have to do this at all.

 

I know, I'm just lol, but really, if you can disable them or take your OEM sensors out, throw them in some tubes and inflate to 30-35psi, whichever is the OEM recommendation, you'll never have to worry about it again

 

Thanks for the info john... That was mostly what I was worried about, breaking the bead. As for the sensors that I have, it's not because it's losing communication with the car, it's because it has never been married yet. Apparently it goes to sleep when it's unmarried and doesn't receive a signal back. Thing of it is though, is that this is a specific brand feature. From what I understand, there are other brands of sensors out there that continually emit RF signals or get triggered on by rotation of the tires. However, those brands will have much less battery life then this orotek brand does.

 

Oh I hear ya… Again, I'm all new to this TPMS issue thing. I've never had to purchase an aftermarket set of wheels with TPMS. Hindsight, I would have asked them to put OEM Ford sensors in there instead.

 

And yet the idiots that need them still don't use them/ignore them. "Oh that light, yeah it's been on for a few weeks". Well you're gonna need a new tire you ruined it by driving on it while it was flat
Or they come in freaking out about the light on, on their dash. "I haven't driven the car for a week because I didn't know what the light was"...(sigh) you could've just stopped at a gas station and put 2 lbs of air in your tire and it would've went off smh
