Alright guys I'm not to savay with the new technology on these newer vehicles. I'm buying new tires for my '07 GMC and I'm wondering if I really need to replace the TPMS like discount tire says I do. I'm buying my tires online and having a small local shop install them but was wondering if I should take discount tire's advice and get the TPMS rebuild kit?

I'm currently looking at tires on tirerack.com and onlinetires.com so if you guys have any better websites to buy tires that would help as well.

No

Besides, they are probably still under warranty.

Ask them to put new valve cores in it if its the integrated valve stem/sensor.

IIRC its banded on the rim on the 2007

So I finally ordered my tires and will have them installed on Friday. Do I need to do anything special since it is banded on the rim?

nope, but make sure the tire guy knows they're there.

The only time there is any reason to rebuild/replace anything for the TPMS sensor in the wheel is if it damaged during removal/installation. The sensors are not serviceable. The sensors do not have to be removed to replace the tires.

Have them rebuilt every other tire purchase

Really it depends on the condition. Generally, every other tire change is good. Definitely no longer than that

Kind of random note for those looking at midsize sedans, the current mazda 6 doesnt use in wheel TPMS. It gauges a pressure loss based on difference in wheel speed through abs sensors. No battery replacements or TPMS servicing.

But it only has an idiot lamp so you have to figure out which one is low, nor can you check the current pressures from inside the car.

Like the old days?

None of our cars tell us which tire is low.

Same. Guess I'm a lolpoor.

I had no idea you could refuse the TPmS rebuild. Good to know.

Bump.....

Going to get new tires from Discount Tire this weekend & wanted to check out if this TPMS rebuild kit for $8 per tire is a scam or if it isn't a bad idea to have them do it....

Got new tires from DT ~4-years ago and I declined the TPMS rebuild kit. Everything still works just fine.

Never ever necessary on a Honda unless they break a sensor, the direct system kind. Indirect are impossible to break (well I am sure they CAN be broken, but have to go out of your way to do so)

You would be mistaken. You do realize that they are replacing seals and the nut right? They're not opening the sensor and messing with a circuit board.

What happens to rubber over time? It deteriorates and leaks develop.

What happens to metal over time? It corrodes.

When the stem of your TPMS sensor ends up breaking due to corrosion, YOU'RE going to pay for a new sensor at the tune of $75 each. It's not the shop's fault your sensors are corroded.

You may now question the odds of either scenarios taking place. Well I've lost count of how many times I've rebuilt sensors due to leaks and replaced broken sensors due to corrosion. That's only working at the smallest store in the Houston region also.

Never once seen the seal leak since the systems were installed in 2007. Every time is overkill. The sensor appears to be made of aluminum(or some other light weight non corrosive metal) and plastic.

If you want to err on the side of caution, do every 3rd or 4th set of tires.

Replaced 1000's of bad sensor on Hondas, never once for leaking. Either broke upon installation(the usual) or internal battery failure.

But fault no one for precaution if they so choose. The new indirect system eliminates all this anyways.

Edit: I am not near the corrosive salt air either.

Well seals the can leak and should be replaced.

Also, aluminum can corrode.

I agree with that, they CAN leak, but when they get to the worn out point and need replacing, the battery is about worn out anyways. I just feel replacing it every single time is equal to replace the valve cover gasket each oil change. The valve cover might leak, but in reality probably will not. Aluminum can corrode but has about the slowest corrosion rate among metals.

Just my personal preference, nothing more.
