lazyTLer

hey guys

longtime lurker here on acurazine and recently bought a used 08 TL from a private party . i'm in the process of replacing the tires and am looking at going with the michelin mxm4s.

i did a search, but didn't find anything on this here. at america's tire, they have something called the TPMS rebuild kit for 30 bucks (7.50 x 4). is this needed or worth it? or is this just garbage that they are trying to sell to drive up their margins?

thanks, and looking forward to learning a whole lot more on here!

When replacing tires on a TPMS equipped vehicle, it is recommended to replace the components of the sensor that are susceptible to wear and corrosion from the elements. Our TPMS Rebuild Kits contain all the necessary components for replacement. Warning: Using standard valve stem parts in your TPMS Sensor will damage the sensor

I have never once used this rebuild kit and never had any problems. I personally think its a way for them to squeeze a few more bucks out of you when using their services. Save yourself the money dont bother with the kit. I could be wrong but I dont even think they touch the tpms sensor or o-rings when doing a tire replacement. If there are currently no issues then I certainly wouldnt buy the kit.
I say no!

Hope this helps.

No way. And I'll bet that if you went for it, they wouldn't really install it.

Not really needed. They asked me the same thing. At that price, I can find brand new TPMS in the BM or from a vendor.

It's always a good idea to replace the seals etc when changing the TPMS sensors over, but I've only run into 3 that wouldn't seal as the rubber had hardened/cracked and needed replacement. Problem is that the shop doesn't notice it at the time of installation and as the air leaks out very slowly, it takes some time before the tire goes soft. Also best not to crank done on the nut as the torque is very low, maybe 60/70 inch lbs.

wth? 60/70 inch lbs? you do realize that translates to 720/840 foot lbs....even lug nuts only need about 80 ft lbs. you will break almost any nut in the car if you tried applying 840 ft lbs on it. thats like saying you have a breaker car of 2 feet, and have a 420 pounds fat man sitting on the end of the breaker bar.

Better check your calculations as 60 inch lbs is 5 ft lbs.
720 ft lbs is 8640 inch lbs. You've got the math backwards, divide by 12 not multiply by 12.

Thanks for the info guys! You saved me $30!

Usually you only need to worry about that if they remove the TPMS, but most of the time thye don't need to touch it.

How long do TPMS sensors usually last? I'm going to be putting on new tires soon and my current sensors are from 2007. I expect my new tires to last me 5-6 years and don't want to have dismount and re-balance if one goes bad in that time frame.

It depends... The original ones in my Infiniti are still working 7 years later... But I bought new ones to put in my aftermarket wheels... One of the batteries in those died after only 6 months. I'm guessing the TPMS was just pulled from stock, and was an older unit... But from what I hear, typical life of the battery in the TPMS is between 6-10 years, depending on how often you drive your car.

That rebuild kit won't help you in that situation, because the only way to replace the battery, is to replace the entire TPMS sensor, becuase it's a sealed unit. And when you buy a new TPMS sensor, it comes with all those seals and crap already...

I would have done it if I was you, I used to work at Discount Tire. You wouldn't believe the number of Honda/Acura's that came in with leaking TPMS sensors all because the gaskets dry out or cracked, especially if you live in a snowy climate.
