Question about TPMS sensor 'kit' needed if just changing tires

Hey folks, I already bought a kit for my M3 wheels siince I'll be powdercoating them and need to remove the sensors, but need to replace tires on wife's car, and Discount Tire are feeding me the BS that they need to be replaced at the tune of $30, when the freaking kit costs $11 online shipped. Told them that and said the rest was 'labor'; gimme a freaking break.

I was going to order the kit and swap it myself (takes a minute each at the most), but am questioning if I need to do that if car is only 3 years, 35K miles old.

Seems to me a nice way to make a buck, but want an expert opinion if I should remove the sensors to install a new kit when I have no leaks. When it comes the time to replace sensors (about 5 years, I'm told), I'd obviously get a kit then.

So what's the gang's opinion? Buy a TPMS kit if you're just replacing tires on same wheels/sensors or not? Thanks.

My question was not to replace the sensors, which I'd do until they fail indeed.

The question was if we should listen to tire places saying we need to remove sensors from wheels and put new rubber seals, valve cores, outer nuts, and washers (all sold in a kit like this one: http://cgi.ebay.com/ebaymotors/TPMS-...Q5fAccessories) when only replacing tires (same wheels, same sensors). Am I making sense now???

I personally don't see the need to mess with the sensors at all since they don't have to be removed for a tire change, but want to hear from the experts.

That's what I suspected. Thanks man. Will tell Discount Tire to leave the sensors alone. Take care.

Most Tire Places Want to Replace Valves

Part of the deal is that typical pass car & SUV tires can be on vehicles for many years. Plus, it's likely a largely unnoticed (by the customer) extra profit item.

This practice has cost Discount in the past as they had a big recall over valve stems sourced from China that had some premature failures.

Yeah, had to ask the guy three times for the breakdown, and didn't even mention the kit. Only after adding them up and multiplying the tax I noticed it was $30 over. Creeps.

Glad you mentioned that. Will check the kit I bought from Ebay, but I can almost guarantee you is made in China too. In fact, it's very likely the ones from the factory might be made there as well, but when I remove the sensors for the PC job, will check all the parts out and decide if they need replacing or not, as car only has 3K miles. Oh, and I'll powdercoat the silver 'nuts' too . Good day folks.

Yes, Hard to Avoid

Many low tech items come from China. It was actually Chinese source Dill branded valves that were the issue. It's been a couple of years. It should be mostly sorted. Ebay sourcing does add some uncertainty.

Additional TPMS Sensor Info

I remembered that there was quite a bit of info in a previous thread about the life of TPMS sensors and reusing them. I found the info: http://www.m3post.com/forums/showpos...75&postcount=5

I went looking because I was concerned about sensor shelf life after the OP said that he bought a kit off ebay, but now that I've looked at the ebay link, I see that the kit is only the TPMS compatible valve steems; so, it's not an issue. Still, the linked information from Lemans_Blue_M is worth reading

I'd tell them to pound sand. If one fails then change it...
