Well I am not saying that it will or not as I have yet to experience a flat in the SC. Plus i do not see where anyone here has used this item or fix a flat on an SC with the sensors. I know that it supposed to be compatible with tire pressure sensors-but WHY? I am more interested in the technical aspects vs the advertising portion of their claims. Plus many here do not have sensors on their non run flat setup like myself. As I do not sell this item at my stores and information is limited in searches I am curious about the product myself. I am not going to speak for others here but for me I would rather be on the road quickly and deal with the tire pressure/rim/tire later vs. being stranded on the side of the road waiting for some tow truck and possibly someone that has no idea how to take care of a nice car. But...that is me.

I think I was the first to talk about this some time ago. I haven't used mine yet, but my understanding is that the sealant is "water based" and will not harm the sensors.

Hmmm, don't know. The real question I have is how does it damage the sensors? See my post here which shows how well the sensor is sealed.

Only problem I see is that it MAY block sensor hole of the TPS.

Here is a very nice write up which discusses much of this incl water based sealants.

Well, until one of us tries it we won't really know and I for one hope none of us ever find out
It would seem logical that the sensor should be able to be cleaned given the solvents water base. It shouldn't be that bad, messy but able to be flushed clean.

One thing for sure, I can't tell you how much I enjoy my car now that i ditched the runflats.

Well, I enjoyed the car with the runflats for more than four years, but recently ditched the runflats for regular Michelins, at the recommendation of the Lexus Service Manager, and they are wonderful. Smoother, quieter and they corner better.

At about that same time, I heard of the water based Conti Tire kit, and have one stashed in the trunk in case i need it in a dire emergency where AAA is not enough.

It sounds like it should work with our pressure sensors, but I hope I'm not the one to make the first (or second) report on it.

Not to seem negative, but if someone is going to test it, it will be me. I go through more tires/wheels than anyone I know of.

I have read in this forum that the solution to not having a spare is the ComfortKit as it will not clog up the pressure sensors. I recently ran across a very inexpensive repair kit from Slime -- the Smart Spair kit. It includes a can of Slime and an inflation pump all for under $20. Does anyone know what the effects of Slime on the tire pressure sensors? I bought it for my daughter, but looks like a potential solution which is less expensife than the $75 kit from Continental.

The guy at Tire Rack says that the sealant in this kit is water soluable and should not ruin the sensor because it can be washed off. . I called Continetal tire and the rep spoke with a technical advisor there and he said it could be a problem. So, I am at a loss as to who is right.

Question emailed to to Brandon @ Tire Rack:

I have a 2006 SC 430 with runflats which I would like to change. I am afraid of not having a spare.
Will the confort kit's gel ruin the sensors in my car if I needed to use it?

thanks

His answer:

Yes it will ruin them.

yes it will ruin them. and they're not cheap to replace either...something like $200 a pop.

Get a AAA towing service or a Toyota supra $50 spare donut on ebay or if you care about how your trunk will look, you can get a spare tire kit with carpet, trim and all the fixings on ebay also.
Do a search here...it's been discussed numerous times.

and aaa service is free during the manufacturer warranty

Hey, how about we all pitch in $10 bucks and have someone actually try it? Just kidding, obviously, but Brandon's answer could be "were not going to take the risk" more than he's a chemical engineer and has the answer, especially given that the Conti people (who should know but have a vested interest) say its AOK.

A new set of 4 tire sensors cost you $349.
That is $88 per sensor plus they only last a few years.

I better stay with runflats because $88 is a lot of money for me to maintain a $60k car.

Plus, you might lose the valve stem cap which also costs money. If you have a full-sized spare, there is no having to unscrew the cap and thus no chance to lose it.

straight from Tirerack:

"This product's sealant may interfere with the tire pressure monitoring sensors on vehicles with direct TPMS, possibly leading to error prompts and incorrect pressure readings. Use of this product on direct TPMS vehicles could also result in damage to the tire pressure sensor inside the wheel. Please contact your sales specialist at The Tire Rack for more information."
