I am not discounting anything that anyone has said so far. It all seems consistant with the research that I have done this afternoon. There are a few points though that seem to come up that I think would be valuable to address to anyone who is thinking of using the sealant.



First, there is the frequent comment that it throws the tire off balance. That, I assume, is why on the instructions it explicitly says to drive the car for at least 4 or 5 miles after filling the tire. I had heard in the past, that if you just put it in, the material will settle to the bottom of the tire and harden. That would certainly cause a balance problem. The can said that after filling to drive it a distance to distribute the material around the inside of the tire. I also recall being told, I think by the auto parts salesman to go to the nearest gas station to check the pressure and adjust to proper specs. That would be, I assume, be because the contents of the can are measured for a wide range of cars with varying pressure requirements. I have seen 2 products on the shelf also. One for trucks and suvs and the other for cars. I would assume you also want to make sure that you are getting the right product for your vehicle. (Car or Truck/SUV) Also, the can itself, mentioned how it continues to expand some after filled. It said to use the whole can in your tire. Thus to a point in the last post about using 2 cans. If the tire isn't fully inflated with 1 can that isn't, as I understand, necesarrily a problem. You shouldn't add a second can. 1 can should be enough for you, as the instructions indicated, to go to a nearby service station and add additional air or get the tire fixed.



I re-read the can this afternoon and there was mention exactly as the previous writer stated, that the product is intended as a short term fix to get you to a repair shop to have the tire properly inspected and repaired. This brings up a question now. I did exactly that but the only service that the repair shop was prepaired to do was sell me 2 new tires. Not being able to find a leak in the tire, they didn't suggest any other remedy. If that is the case, I would think that the manufacturer (Penzoil) should say on the can that use of their product will require you to get 2 new tires. Of course, I am being sarchastic here. In reality, should I then go to another tire shop and have them take the tire apart, clean it, find the problem and put it back together? Or, would I be safe, seeing that the previous service center said that there is no appearent leak to let it go for the remaining life of the tire, considering that the tread only has a couple months or thousand miles left anyway?



Lastly, I found info that Penzoil had removed and recalled the product, in 1999. The recalls seemed to indicate issues that might be related to flamability. The can that I just bought, specifically, mentions that it is a "NON-FLAMABLE" material. Most of the issues that I had read about were on boards and groups similar to this and were all dated as much as 8 years ago. I found no mention, other than here, of anything more to date. Is it possible that newer formulations of rubber, as the can I bought said that it contained, and NON-Flamable, might be different?



I make the points above only because there is the question of whether the user of the product isn't following the instructions on the container. Using my can as a guide, there was mention of DO NOT USE IT IN BICYCLE TIRES. LAWN EQUIPMENT.... That the product is intended for use only in automobile tires... Drive the vehicle to distribute the material in the tires. If the wheel doesn't lift off the ground than take the tire for repair. After using the product, see a repair person as soon as possible. As for a fee to clean up the stuff.... I would have had no problem with that. I even offered to pay for them to remove the tire and check it for leaks. The salesman declined saying that he didn't do anything. Only problems that I do have in my situation is paying $275 for 2 tires , (Right Now) if that isn't necessary. Also, I would think it a little cheezy if I had gone in and bought new tires, 2 for $275 or 4 for about $590 and being charged extra for cleaning up the fix a flat. I note that my service consultant didn't quote anything to clean up the wheel... His quote included, warranty and alignment and installation.
